“Beam Me Up Scotty” ~ Teleportation of light particles across cities in China and Canada a ‘technological breakthrough’!

Scientists have shown they can teleport matter across a city, a development that has been hailed as “a technological breakthrough”.

However, do not expect to see something akin to the Star Trek crew beaming from the planet’s surface to the Starship Enterprise. star-trek-transporter-1280jpg-883390_1280w

Instead, in the two studies, published today in Nature Photonics, separate research groups have used quantum teleportation to send photons to new locations using fibre-optic communications networks in the cities of Hefei in China and Calgary in Canada.

Quantum teleportation is the ability to transfer information such as the properties or the quantum state of an atom — its energy, spin, motion, magnetic field and other physical properties — to another location without travelling in the space between.

Key points

  • Two experiments demonstrate teleportation of particles across real optical fibre networks for first time
  • Chinese experiment transports two photons per hour across seven kilometres
  • Canadian experiment transports 17 photons per minute across 6.2 kilometres

 

While it was first demonstrated in 1997, today’s studies are the first to show the process is technologically possible via a mainstream communications network.

The development could lead to future city-scale quantum technologies and communications networks, such as a quantum internet and improved security of internet-based information.

Dr. Ben Buchler, Associate Professor with the Centre for Quantum Computation and Communication Technology at the Australian National University, said the technical achievement of completing the experiments in a “non-ideal environment” was “pretty profound”.

“People have known how to do this experiment since the early 2000s, but until these papers it hasn’t been performed in fibre communication networks, in situ, in cities,” said Dr. Buchler, who was not involved in the research.

“It’s seriously difficult to do what they have done.”

A cornerstone of quantum teleportation is quantum entanglement, where two particles are intimately linked to each other in such a way that a change in one will affect the other.

Dr. Buchler said quantum teleportation involved mixing a photon with one branch of the entanglement and this joint element was then measured. The other branch of the entanglement was sent to the receiving party or new location.

This original ‘joint’ measurement is sent to the receiver, who can then use that information to manipulate the other branch of the entanglement.

“The thing that pops out is the original photon, in a sense it has indistinguishable characteristics from the one you put in,” Dr Buchler said.

Overcoming technical barriers

He said both teams had successfully overcome technical barriers to ensure the precise timing of photon arrival and accurate polarisation within the fibres.

The Chinese team teleported single protons using the standard telecommunications wavelength across a distance of seven kilometres, whiled the Canadian team teleported single photons up to 6.2 kilometres.

But work remained to increase the speed of the system with the Chinese group teleporting just two photons per hour and the Canadians a faster rate of 17 photons per minute.

Dr. Buchler said the speeds meant the development had little immediate practical value, but “this kind of teleportation is part of the protocol people imagine will be able to extend the range of quantum key distribution” — a technique used to send secure encrypted messages.

In the future scientists envision the evolution of a quantum internet that would allow the communication of quantum information between quantum computers.

Quantum computers on their own would allow fast computation, but networked quantum computers would be more powerful still.

Dr. Buchler said today’s studies were a foundation stone toward that vision as it showed it was possible to move quantum information from one location to another within mainstream networks without destroying it.

Yes … a LOT more work has to be done however before we “Warp” and “Beam” … but to put it into the words of ‘The Good Doctor’ …

“Damit Jim, I’m ONLY a doctor!” (Highly Logical) “Live long and Prosper!”

Calgary, Alberta, The Inc. brings Calgary startups together under one roof


Calgary Innovate logo-png-5A visionary combination of physical accommodations and shared community is a step closer to reality following approval of the final stages of development and implementation at The Inc.

The Inc. is a new co-working program in Calgary; a bricks-andmortar building that offers an environment of ideas and innovation. Recognizing that working space can be a challenge for startup businesses to find and afford, program developers at Innovate Calgary implemented a unique model that makes available the hard walls of a physical space and the soft boundaries of a virtual environment.

The dedicated 2,000-squarefoot space at the Alastair Ross Technology Centre will house up to 30 new companies, including conference rooms, phone areas and communal workspaces.

As Steve McIlvenna, director of entrepreneur development at Innovate Calgary, describes it, the space will be home to timely coaching, relevant mentoring and other programming that supports business development.

McIlvenna, an innovator and inventor himself, knows full well that entrepreneurs need a combination of skills, knowledge and support to succeed. A great idea, invention or unique market proposition is crucial, of course, but successful startups must also get validation in the real world, and demonstrate they have “compelling proof of customer. The Inc. helps keep their feet to the fire in a good way,” he said. “Entrepreneurs help entrepreneurs through professional networking and open communication. It’s social, it’s collaborative, it’s often informal. There’s access to our business acceleration and product commercialization programs. But it all happens on their timetable, at a cadence they are comfortable with.”

That’s what Rafique Awan liked about the co-working concept. He’s a client of microInc, the program that piloted The Inc.’s launch. He’s also founder of QueueSmart, a startup tech company that has developed a mobile app to reduce medical wait times.

“I started doing my own search for office space, but that took a lot of time and what I found was too expensive for me as a startup,” he said. “Finding and joining microInc was immensely helpful for me, not just for the workspace, but all the advice that was shared there helped me understand the validation process, and how to learn more about my target market.”

The power of co-working is that it opens opportunities for peer and partner support, something McIlvenna encourages.

“No startup becomes successful with only one captain in the ship, and serendipity is a central component to the overall effect of the Inc.,” he said. “The synergy that can happen while working with other talented, innovative people is tremendous.”
