Cold atoms offer a glimpse of flat physics – New Particles (Anyons) could one Day Power a Special Breed of Quantum Computers

These days, movies and video games render increasingly realistic 3-D images on 2-D screens, giving viewers the illusion of gazing into another world. For many physicists, though, keeping things flat is far more interesting.

One reason is that flat landscapes can unlock new movement patterns in the quantum world of atoms and electrons. For instance, shedding the third dimension enables an entirely new class of particles to emerge—particles that that don’t fit neatly into the two classes, bosons and fermions, provided by nature.

These new particles, known as anyons, change in novel ways when they swap places, a feat that could one day power a special breed of quantum computer.

But anyons and the conditions that produce them have been exceedingly hard to spot in experiments. In a pair of papers published this week in Physical Review Letters, JQI Fellow Alexey Gorshkov and several collaborators proposed new ways of studying this unusual flat physics, suggesting that small numbers of constrained atoms could act as stand-ins for the finicky electrons first predicted to exhibit low-dimensional quirks.

“These two papers add to the growing literature demonstrating the promise of cold atoms for studying exotic physics in general and anyons in particular,” Gorshkov says. “Coupled with recent advances in cold atom experiments—including by the group of Ian Spielman at JQI—this work hints at exciting experimental demonstrations that might be just around the corner.”

In the first paper, which was selected as an Editors’ Suggestion, Gorshkov and colleagues proposed looking for a new experimental signature of anyons—one that might be visible in a small collection of atoms hopping around in a 1-D grid. Previous work suggested that such systems might simulate the swapping behavior of anyons, but researchers only knew of ways to spot the effects at extremely cold temperatures.

Instead, Fangli Liu, a graduate student at JQI, along with Gorshkov and other collaborators, found a way to detect the presence of anyons without needing such frigid climes.

Ordinarily, atoms spread out symmetrically over time in a 1-D grid, but anyons will generally favor the left over the right or vice versa. The researchers argued that straightforward changes to the laser used to create the grid would make the atoms hop less like themselves and more like anyons. By measuring the way that the number of atoms at different locations changes over time, it would then be possible to spot the asymmetry expected from anyons. Furthermore, adjusting the laser would make it easy to switch the favored direction in the experiment.

“The motivation was to use something that didn’t require extremely cold temperatures to probe the anyons,” says Liu, the lead author of the paper. “The hope is that maybe some similar ideas can be used in more general settings, like looking for related asymmetries in two dimensions.”

In the second paper, Gorshkov and a separate group of collaborators found theoretical evidence for a new state of matter closely related to a Laughlin liquid, the prototypical example of a substance with topological order. In a Laughlin liquid, particles—originally electrons—find elaborate ways of avoiding one another, leading to the emergence of anyons that carry only a fraction of the electric charge held by an electron.

“Anyons are pretty much still theoretical constructs,” says Tobias Grass, a postdoctoral researcher at JQI and the lead author of the second paper, “and experiments have yet to conclusively demonstrate them.”

Although fractional charges have been observed in experiments with electrons, many of their other predicted properties have remained unmeasurable. This makes it hard to search for other interesting behavior or to study Laughlin liquids more closely. Grass, Gorshkov and their colleagues suggested a way to manipulate the interactions between a handful of atoms and discovered a new state of matter that mixes characteristics of the Laughlin liquid and a less exotic crystal phase.

The atoms in this new state avoid one another in a similar way as electrons in a Laughlin liquid, and they also fall into a regular pattern like in a crystal—albeit in a strange way, with only half of an atom occupying each crystal site. It’s a unique mix of crystal symmetry and more complex topological order—a combination that has received little prior study.

“The idea that you have a bosonic or fermionic system, and then from interactions there emerges completely different physics—that’s only possible in lower dimensions,” Grass says. “Having an experimental demonstration of any of these phases is just interesting from a fundamental perspective.”

A New Quantum Computer Module – Programmable Ions Set the Stage for General-Purpose Quantum Computers


JQI Q Computer 080416 cover_galleryClose-up photo of an ion trap. Credit: S. Debnath and E. Edwards/JQI

“Making a quantum computer that can run arbitrary algorithms requires the right kind of physical system and a suite of programming tools. Atomic ions, confined by fields from nearby electrodes, are among the most promising platforms for meeting these needs.”

Quantum computers promise speedy solutions to some difficult problems, but building large-scale, general-purpose quantum devices is a problem fraught with technical challenges.

To date, many research groups have created small but functional quantum computers. By combining a handful of atoms, electrons or superconducting junctions, researchers now regularly demonstrate quantum effects and run simple quantum algorithms—small programs dedicated to solving particular problems.

But these laboratory devices are often hard-wired to run one program or limited to fixed patterns of interactions between their quantum constituents. Making a quantum computer that can run arbitrary algorithms requires the right kind of physical system and a suite of programming tools. Atomic ions, confined by fields from nearby electrodes, are among the most promising platforms for meeting these needs.

In a paper published as the cover story in Nature on August 4, researchers working with Christopher Monroe, a Fellow of the Joint Quantum Institute and the Joint Center for Quantum Information and Computer Science(link is external) at the University of Maryland, introduced the first fully programmable and reconfigurable quantum computer module(link is external). The new device, dubbed a module because of its potential to connect with copies of itself, takes advantage of the unique properties offered by trapped ions to run any algorithm on five quantum bits, or qubits—the fundamental unit of information in a quantum computer.

“For any computer to be useful, the user should not be required to know what’s inside,” Monroe says. “Very few people care what their iPhone is actually doing at the physical level. Our experiment brings high-quality quantum bits up to a higher level of functionality by allowing them to be programmed and reconfigured in software.”

The new module builds on decades of research into trapping and controlling ions. It uses standard techniques but also introduces novel methods for control and measurement. This includes manipulating many ions at once using an array of tightly-focused laser beams, as well as dedicated detection channels that watch for the glow of each ion.

“These are the kinds of discoveries that the NSF Physics Frontiers Centers program is intended to enable,” says Jean Cottam Allen, a program director in the National Science Foundation’s physics division. “This work is at the frontier of quantum computing, and it’s helping to lay a foundation and bring practical quantum computing closer to being a reality.”

The team tested their module on small instances of three problems that quantum computers are known to solve quickly. Having the flexibility to test the module on a variety of problems is a major step forward, says Shantanu Debnath, a graduate student at JQI and the paper’s lead author. “By directly connecting any pair of qubits, we can reconfigure the system to implement any algorithm,” Debnath says. “While it’s just five qubits, we know how to apply the same technique to much larger collections.”

At the module’s heart, though, is something that’s not even quantum: A database stores the best shapes for the laser pulses that drive quantum logic gates, the building blocks of quantum algorithms. Those shapes are calculated ahead of time using a regular computer, and the module uses software to translate an algorithm into the pulses in the database.

Putting the pieces together

Every quantum algorithm consists of three basic ingredients. First, the qubits are prepared in a particular state; second, they undergo a sequence of quantum logic gates; and last, a quantum measurement extracts the algorithm’s output.

The module performs these tasks using different colors of laser light. One color prepares the ions using a technique called optical pumping, in which each qubit is illuminated until it sits in the proper quantum energy state. The same laser helps read out the quantum state of each atomic ion at the end of the process. In between, a separate laser strikes the ions to drive quantum logic gates.

These gates are like the switches and transistors that power ordinary computers. Here, lasers push on the ions and couple their internal qubit information to their motion, allowing any two ions in the module to interact via their strong electrical repulsion. Two ions from across the chain notice each other through this electrical interaction, just as raising and releasing one ball in a Newton’s cradle transfers energy to the other side.

How it works: The first programmable quantum computer module based on ions

The re-configurability of the laser beams is a key advantage, Debnath says. “By reducing an algorithm into a series of laser pulses that push on the appropriate ions, we can reconfigure the wiring between these qubits from the outside,” he says. “It becomes a software problem, and no other quantum computing architecture has this flexibility.”

To test the module, the team ran three different quantum algorithms, including a demonstration of a Quantum Fourier Transform (QFT), which finds how often a given mathematical function repeats. It is a key piece in Shor’s quantum factoring algorithm, which would break some of the most widely-used security standards on the internet if run on a big enough quantum computer.

Two of the algorithms ran successfully more than 90% of the time, while the QFT topped out at a 70% success rate. The team says that this is due to residual errors in the pulse-shaped gates as well as systematic errors that accumulate over the course of the computation, neither of which appear fundamentally insurmountable. They note that the QFT algorithm requires all possible two-qubit gates and should be among the most complicated quantum calculations.

The team believes that eventually more qubits—perhaps as many as 100—could be added to their quantum computer module. It is also possible to link separate modules together, either by physically moving the ions or by using photons to carry information between them.

Although the module has only five qubits, its flexibility allows for programming quantum algorithms that have never been run before, Debnath says. The researchers are now looking to run algorithms on a module with more qubits, including the demonstration of quantum error correction routines as part of a project funded by the Intelligence Advanced Research Projects Activity(link is external).

 

What are Quantum Dots?


Introduction

Over the past few years, fluorescent semiconductor nanoparticles have gained a lot of importance. In comparison with traditional fluorescent dyes, they show considerable benefits. These nanocrystals comprise an inorganic core and the composition and size of the inorganic core decide their optical characteristics (Figure 1).

Figure 1. Quantum dots

The core features excellent fluorescence properties as it exhibits high stability against environmental conditions such as irradiation, air or temperature. The stabilization of organic molecules surrounding this inorganic core enables solubility in organic solvents such as toluene, hexanes or chloroform. It is possible to obtain dispersibility in aqueous media without losing the quantum dot’s original properties by interchanging these organic ligands in the outer sphere via water soluble molecules.

Light absorption used for excitation in the case of nanoparticles is normally larger when compared to fluorescent dyes. Hence the detection of these particles can be done at very low concentrations and even a single particle could be investigated using spectroscopic methods.

Semiconductor Nanoparticles

Semiconductor nanoparticles are the most studied system among fluorescent particles. By modifying the particle size, the band gap of these systems and therefore the emission wavelength can be manipulated. Hence these systems are highly attractive. The smaller the quantum dot size, the bigger is the band-gap and shorter is the emitted light wavelength. This effect is termed as size quantization.

By taking a collective decision on material size and composition, it is possible to cover the complete visible light spectrum up to the IR region. Using this concept, CAN has developed the CANdots Series A, B and C.

CANdots Series

The CANdots series from CAN covers the following:

  • Series A covers the spectrum’s visible region having emission wavelengths from 500 to 650nm
  • Series B covers the spectrum’s near IR section with emission wavelengths from 650 to 800nm
  • Series C covers the spectrum’s IR region with emission maxima more than 1000nm

As the absorption increases from the emission maximum while moving towards shorter wavelengths, the nanoparticles can be excited with all wavelengths below the emission. In comparison with organic fluorescent dyes, it is not necessary to reset the excitation wavelength for each dye. A complete set of a variety of nanoparticles can be excited all together with a single excitation wavelength and their emission can be detected.

After excitation, i.e. after light absorption, an electron-hole pair is generated in semiconductor nanocrystals. This exciton or electron-hole pair is free to move within the core until recombination or emission of light occurs. During this time (typically around 10-20ns), the charge carriers may be bound at some other place and consequently there may be a decrease in emission intensity.

In order to prevent this, the semiconductor nanoparticles or cores were enclosed by passivating inorganic shells. The particle stability is improved with these shells. In addition, there is an improvement in the quantum yield of the system such as in CAN Series A core/shell (CdSe/CdS) and core/shell/shell (CdSe/ZnSe/ZnS) systems.

Vaporware: Scientists Use Cloud of Atoms as Optical Memory Device


QDOTS imagesCAKXSY1K 8Talk about storing data in the cloud. Scientists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have taken this to a whole new level by demonstrating* that they can store visual images within quite an ethereal memory device—a thin vapor of rubidium atoms. The effort may prove helpful in creating memory for quantum computers.

This brief animation (click link to launch mp4) by the NIST/JQI team shows the NIST logo they stored within a vapor of rubidium atoms and three different portions of it that they were able to extract at will. Animation combines three actual images from the vapor extracted at different times.

Their work builds on an approach developed at the Australian National University, where scientists showed that a rubidium vapor could be manipulated in interesting ways using magnetic fields and lasers. The vapor is contained in a small tube and magnetized, and a laser pulse made up of multiple light frequencies is fired through the tube. The energy level of each rubidium atom changes depending on which frequency strikes it, and these changes within the vapor become a sort of fingerprint of the pulse’s characteristics. If the field’s orientation is flipped, a second pulse fired through the vapor takes on the exact characteristics of the first pulse—in essence, a readout of the fingerprint.

“With our paper, we’ve taken this same idea and applied it to storing an image—basically moving up from storing a single ‘pixel’ of light information to about a hundred,” says Paul Lett, a physicist with JQI and NIST’s Quantum Measurement Division. “By modifying their technique, we have been able to store a simple image in the vapor and extract pieces of it at different times.”

It’s a dramatic increase in the amount of information that can be stored and manipulated with this approach. But because atoms in a vapor are always in motion, the image can only be stored for about 10 milliseconds, and in any case the modifications the team made to the original technique introduce too much noise into the laser signal to make the improvements practically useful. So, should the term vaporware be applied here after all? Not quite, says Lett—because the whole point of the effort was not to build a device for market, but to learn more about how to create memory for next-generation quantum computers.

“What we’ve done here is store an image using classical physics. However, the ultimate goal is to store quantum information, which a quantum computer will need,” he says. “Measuring what the rubidium atoms do as we manipulate them is teaching us how we might use them as quantum bits and what problems those bits might present. This way, when someone builds a solid-state system for a finished computer, we’ll know how to handle them more effectively.”

Nanosys Closes Sixth Funding Round: $15M New Investment to expand quantum dot manufacturing


nanosys Series F-01 Palo Alto, Calif., November 26, 2012 – Nanosys Inc., an advanced materials architect, today closed a $15 million sixth round of funding. The company will use the new investment to expand its quantum dot manufacturing capabilities. Nanosys’ flagship quantum dot product is Quantum Dot Enhancement Film™ (QDEF), which vastly improves the color performance and efficiency of Liquid Crystal Displays (LCDs).

“You’ve never seen anything like a quantum dot display,” said Jason Hartlove, President and CEO of Nanosys. “We are working with display makers to create a new high color gamut display experience that is cheaper, more efficient and more reliable than anything else currently on the market. The response from manufacturers so far has been great and demand for QDEF has grown to the point that we’ll need to expand manufacturing to keep up.”

Nanosys will expand its quantum dot manufacturing line more than tenfold in order to meet increasing demand. The expansion will make Nanosys the largest quantum dot manufacturer in the world.

Most current LCDs are only capable of displaying 35 percent or less of the visible color spectrum. This means the viewing experience on an LCD is limited and vastly different from what is seen in the real world, as colors are altered or left out altogether. Wide color gamut displays make the viewing experience on an electronic device much closer to the vibrant visual experience of real life. An LCD powered by QDEF can display 50 percent or more color than a standard LCD. QDEF also provides a significant energy efficiency advantage over other LCD backlight technologies.

QDEF utilizes the light emitting properties of quantum dots to create an ideal backlight for LCDs, which is one of the most critical factors in the color and efficiency performance of the display. A quantum dot, which is 10,000 times narrower than a human hair, can be engineered to emit light at very precise wavelengths. QDEF relies on this unique ability to control the spectral output of a quantum dot to create an ideal white backlight specifically designed for LCDs. Trillions of custom engineered quantum dots are loaded into each sheet of QDEF, which fits inside an LCD backlight unit. The new film replaces one already found inside the LCD backlight, which means the manufacturing process requires no new equipment or process changes for the LCD manufacturer.

High Brightness Tetrapod Quantum Dots Developed


With this advancement, Quantum Materials Corp. Tetrapod Quantum Dots can be produced with a quantum yield greater than 80%, a brightness that increases the performance of this fluorescent marker alternative in biological assays and other applications.PR Newswire (http://s.tt/1tdEj)

 

CARSON CITY, Nev., Nov. 13, 2012 /PRNewswire/ — Millions of laboratory tests and biological assays are conducted every year to explore cellular processes. Quantum Materials Corporation has now developed tetrapod quantum dots, improved fluorescent markers that can more effectively gain knowledge of how body systems function and chronic conditions and diseases such as cancer metabolize and impact health and longevity.
Conventionally, fluorescent tags or tracers have been used to “light up” and distinguish one type of cell from another to gain these insights into biological functions.  However, these tags and other dyes have drawbacks to use, including quick fading and tedious procedures to differentiate more than one type of cell or bio-molecule at a time.

The discovery of quantum dots as a fluorescent marker has made these biochemical assays quicker and more robust for scientific discovery.  The quantum dots are proving to be more stable and have a unique capability to shine in multiple colors under a single light source excitation so that a single assay can produce much more information for researchers.

Quantum Materials Corporation has now increased the brightness of its tetrapod-shaped quantum dots for this application.  At a quantum yield greater than 80%, the dots are bright enough to be functionalized in a wide variety of ways to perform as novel probes into as-of-yet-not-fully-understood biological systems.  This functionalization typically will allow researchers to modify the base quantum dot so that a biological tag can be made with an appropriate protein or antibody for a very specific marking within the laboratory sample.

Quantum Materials’ CEO Stephen Squires noted that, “We believe that the brightness of our Tetrapod Quantum Dots along with other unique features, will give key players in the pharmaceutical and biological industries a much awaited, high performance tool to dig in deeper to the mysteries of physiological conditions that have eluded efforts for cures.”

In combination with Quantum Materials use of high throughput microreactor technology the production of the high quantum yield, bright quantum dots will potentially enable the millions of annual assays to expand significantly in number and provide desperately needed information to be quickly available to the world’s leading researchers.

In addition to the performance increases for biomedical applications, Quantum Materials believes that the technology breakthrough will also enable its subsidiary, Solterra Renewable Materials to increase conversion efficiencies for its thin-film quantum dot solar cell.  With advances in the solar cell, QMC expects to then apply insight gained in the added performance to other quantum dot applications such as LED lighting and displays.

Feds enlist Rice for nanocarbon project


Rice News

National Institute of Standards and Technology grant supports measurement and characterization of nanomaterials

The nascent industry of carbon-based nanomanufacturing will benefit from a new cooperative venture between scientists at Rice University and its Richard E. Smalley Institute for Nanoscale Science and Technology and scientists at the National Institute of Standards and Technology (NIST) in Gaithersburg, Md.

NIST announced a $2.7 million, five-year cooperative research agreement to study how nanoparticles – particularly fullerenes (aka buckyballs), nanotubes and graphene – operate and interact with other materials at the molecular, even atomic, scale.

“The payoff will be grand,” said Rice engineering professor Matteo Pasquali, the principal investigator of the new cooperative agreement to advance methods of measurement and characterization of nanomaterials. The goal is to enable the manufacture of high-end products that incorporate carbon-based nanomaterials for enhanced optical, electrical, mechanical and thermal properties.

“With this agreement, we’re building and expanding on several successful years of collaboration between NIST and Rice,” said Pasquali, a professor of chemical and biomolecular engineering and of chemistry at Rice. “Up to now, the research has focused primarily on the separation, spectroscopy and rheology of carbon nanotubes, but we will now go further to enable products and devices to be manufactured that include many types of carbon nanomaterials.”

“A lot of the research we’ve already done we can map onto the long-term goal of benefiting U.S. manufacturing,” he said.

The range of products that could benefit from advanced nanomaterials is vast, Pasquali said. The new research will help kick start advances in energy, health care, materials science and national security.

“We look forward to leveraging our combined scientific, engineering and standards leadership in nanomaterials to help the U.S. lead in the race toward commercialization and manufacturing,” said Kalman Migler, leader of the Complex Fluids Group of the Materials Science and Engineering Division at NIST.

“The opportunity to work closely with Rice faculty will quicken the pace of realizing carbon-based nanoelectronics,” said Angela Hight Walker, project leader in the Semiconductor and Dimensional Metrology Division at NIST.

Migler and Hight Walker are technical leads from NIST on the joint project.

The Rice grant will be administered by Pasquali and his colleagues, Vice Provost for Research Vicki Colvin, the Kenneth S. Pitzer-Schlumberger Professor of Chemistry and a professor of chemical and biomolecular engineering, and Junichiro Kono, a professor of electrical and computer engineering and of physics and astronomy.

The agreement builds on two earlier cooperative research agreements and a series of NIST workshops at which industry, government and academic researchers were polled about obstacles that remain in the path of efficient manufacturing with nanoscale carbon, from production of components to integration.

The agreement allows Rice to hire a team of postdoctoral associates and researchers who will study ways to disperse and characterize nanomaterials for specific uses, control and measure nano-network structures and create systems for in-line measurements during manufacturing. The new team will be primarily based at NIST headquarters in Maryland, where they will work closely with NIST scientists while also drawing on Rice expertise as they develop new methods.

Carbon at the nanoscale has become one of the most-studied materials by labs around the world since the discovery of the buckyball at Rice in 1986, which brought the Nobel Prize to Rice’s Richard Smalley and Robert Curl. Since then, nanocarbon has taken on new forms with the discovery of the carbon nanotube in the late ’90s and graphene, the single-atomic-layer form of carbon that won a Nobel for its discovers two years ago.

Pasquali’s lab has deep experience working on the dispersal and characterization of carbon nanotubes and graphene, which group members are working toward extruding into fibers that could become essential components in the advanced energy grid envisioned by Smalley.

Kono’s lab focuses on the physics and applications of carbon nanomaterials, with recent breakthroughs on the fabrication of devices based on aligned carbon nanotubes and graphene to control terahertz waves. “We’ve been working closely with NIST scientists Ming Zheng, Jeffery Fagan and Angela Hight Walker on the chirality separation and spectroscopy of single-wall carbon nanotubes,” Kono said. “Their successful enrichment of armchair carbon nanotubes has led to a significant advancement in our understanding of the electronic and optical properties of these one-dimensional metals.”

Colvin’s group has expertise in how nanoparticles interact with the environment and living systems and has recently demonstrated nano-based technology to remove arsenic from drinking water in Mexico.

QMC has a NDA and is in discussions with a large molecular biology company currently successfully marketing recombinant proteins to researchers to functionalize QMC TQD to their own recombinant proteins, antibodies, aptamers, and peptides as value added product to sell to researchers in the life sciences. QMC is actively pursuing this same biotech market for other companies amenable to non-exclusive licensing of our quantum dots for research purposes or joint venture for development of advanced diagnostic tools delivering instant results at low cost or the use of our TQD as a drug delivery platform.

We are a public company traded OTC as QTMM

NanoMarkets OLED Lighting Market Forecast – Q2 2012


SUMMARY

In the past year OLED lighting markets and production infrastructure have evolved.  For example, office lighting has become a key market target for OLED lighting, while other applications no longer command the interest they once did.  At the same time, while some likely future mass producers of OLED lighting seem to be committing more resources, others seem to be failing in their efforts.

With all this in mind, this report provides NanoMarkets’ latest market forecasts for OLED lighting.  Our company has been actively tracking the OLED lighting market for more than five years and this report represents a more detailed forecast than any we have ever produced before.

In this report, we consider the revenue potential for the OLED lighting applications that currently interest the OLED market the most.  We think these have changed since last year and now comprise luxury consumer lighting, decorative lighting for large buildings and showrooms, office lighting, residential lighting and automotive lighting.  Another change in this year’s report is that we have provided a much more detailed analysis of pricing trends in OLED lighting than ever before In particular, in addition to looking at pricing expectations of leading manufacturers, we have also examined the likely roadmaps for pricing by unit, luminance and square meter and how these three measures are likely to correspond.

Obviously, no one can be completely sure of how the developments in the OLED lighting market will ultimately pan out and with that in mind we consider other prominent forecasts for this market including a worse-case scenario in which OLED lighting never succeeds in growing beyond the luxury lighting sector, along with some ultra-optimistic scenarios that have emerged from apparently respectable sources.

The forecasts in this report are in value and volume (square meter and unit) terms and are broken out by applications.  We also consider how the OLED lighting market is likely to be shared among various major countries and regions as it evolves.  Finally, we examine how our forecasts tie in with the emergence of OLED lighting manufacturing capacity, around the world.
