Calgary researchers teleport light particle 6.2 kilometres, raising hopes for ‘quantum internet’

Posted by in categories: internet, particle physics, quantum physics

The team’s article in Nature Photonics says the demonstration ‘constitutes a milestone towards a global quantum internet,’ as it is one of the longest distances over which quantum teleportation has been achieved using a fibre-optic network in this way.


In a “major step” toward practical quantum networking, researchers at the University of Calgary have successfully demonstrated the teleportation of a light particle’s properties between their lab and the city’s downtown area, six kilometres away.

“What is remarkable about this is that this information transfer happens in what we call a disembodied manner,” said physics professor Wolfgang Tittel, whose team’s work was published this week in the journal Nature Photonics.

Teleportation step toward quantum internet

Is everyone ready for a new teleporting net?


Physicists have set a new bar for quantum teleportation: moving information from one place to another without physically sending anything between the locations.

Two separate teams managed to teleport information across several kilometres of optical fibre network in two cities.

Quantum teleportation was just achieved over more than 7 km of city fibre

Posted by in categories: cybercrime/malcode, particle physics, quantum physics

Quantum teleportation just moved out of the lab and into the real world, with two independent teams of scientists successfully sending quantum information across several kilometres of optical fibre networks in Calgary, Canada, and Hefei, China.

The experiments show that not only is quantum teleportation very much real, it’s also feasible technology that could one day help us build unhackable quantum communication systems that stretch across cities and maybe even continents.

Quantum teleportation relies on a strange phenomenon called quantum entanglement. Basically, quantum entanglement means that two particles are inextricably linked, so that measuring the state of one immediately affects the state of the other, no matter how far apart the two are — which led Einstein to call entanglement “spooky action at a distance”.

Quantum effects observed in ‘one-dimensional’ wires

Posted by in categories: computing, particle physics, quantum physics

Researchers have observed quantum effects in electrons by squeezing them into one-dimensional ‘quantum wires’ and observing the interactions between them. The results could be used to aid in the development of quantum technologies, including quantum computing.

Scientists have controlled electrons by packing them so tightly that they start to display quantum effects, using an extension of the technology currently used to make computer processors. The technique, reported in the journal Nature Communications, has uncovered properties of quantum matter that could pave a way to new quantum technologies.

The ability to control electrons in this way may lay the groundwork for many technological advances, including quantum computers that can solve problems fundamentally intractable by modern electronics. Before such technologies become practical however, researchers need to better understand quantum, or wave-like, particles, and more importantly, the interactions between them.

Quantum Teleportation Just Happened For Real

Posted by in categories: internet, particle physics, quantum physics

I remember when this was announced last year; however, I am glad to see the topic highlighted again especially after China’s launch of their Quantum Satellite.


Quantum teleportation is the mystical, far-off in the future idea where quantum information encoded into particles of light can be transferred from one place to another remotely. Except it’s not far-off in the future — it just happened. Teleportation is real and it is here.

The teleportation occurred over several kilometres of optical fibre networks in the cities of Hefei in China and Calgary in Canada.

Science breakthrough – light particles teleported across cities

Posted by in categories: particle physics, quantum physics, science, space travel

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.

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.

Carbon-coated iron catalyst structure could lead to more-active fuel cells

Posted by in categories: nanotechnology, particle physics, transportation

Abstract: Fuel cells have long held promise as power sources, but low efficiency has created obstacles to realizing that promise. Researchers at the University of Illinois and collaborators have identified the active form of an iron-containing catalyst for the trickiest part of the process: reducing oxygen gas, which has two oxygen atoms, so that it can break apart and combine with ionized hydrogen to make water. The finding could help researchers refine better catalysts, making fuel cells a more energy- and cost-efficient option for powering vehicles and other applications.

Led by U. of I. chemistry professor Andrew Gewirth, the researchers published their work in the journal Nature Communications.

Iron-based catalysts for oxygen reduction are an abundant, inexpensive alternative to catalysts containing precious metals, which are expensive and can degrade. However, the process for making iron-containing catalysts yields a mixture of different compounds containing iron, nitrogen and carbon. Since the various compounds are difficult to separate, exactly which form or forms behave as the active catalyst has remained a mystery to researchers. This has made it difficult to refine or improve the catalyst.

For first time, individual atoms seen keeping away from each other or bunching up as pairs

Posted by in categories: climatology, particle physics, quantum physics

Scientists have identified a new method in understanding superconductors, and what one should do to make higher-temperature superconductors even at room temperature. This is certainly a huge deal as we continue to look at ways to build QC machines and devices. Something that my friends at Google should be interested in.


“Learning from this model, we can understand what’s really going on in these superconductors, and what one should do to make higher-temperature superconductors, approaching hopefully room temperature,” says Martin Zwierlein, professor of physics and principal investigator in MIT’s Research Laboratory of Electronics.

If you bottle up a gas and try to image its atoms using today’s most powerful microscopes, you will see little more than a shadowy blur. Atoms zip around at lightning speeds and are difficult to pin down at ambient temperatures.
