Lazaridisbacked QuantumNano Centre opens tomorrow, aims to be a new Bell Labs

Mike Lazaridis may now have a considerably smaller role at RIM, but he's isn't exactly receding from the technology scene in the company's hometown of Waterloo, Ontario. That's no more evident than in the Mike & Ophelia Lazaridis Quantum-Nano Centre opening tomorrow on the University of Waterloo campus, a science and technology research center that not only bears his name but was built with $100 million of his money. As Lazaridis makes clear in an interview with Bloomberg, he's also not modest about his ambitions for the center, noting that it is "absolutely" going to be the Bell Labs of the 21st century. Or, perhaps more specifically, a Bell Labs for quantum computing and nanotechnology, areas of research that Lazaridis says are key in order to "break through those barriers" of traditional computing. You can find the full interview and more details on the center itself at the links below.

Scientists create first quantum router, but don’t throw your 802.11ac out yet

Scientists create first quantum router, but don't throw your 80211ac out yet

A common vision of the future has us with our feet up, while robots do all the work. Another one sees the end of silicon, with quantum computers doing all the heavy lifting. That second prophecy inches just a smidgen closer with the news of the world's first quantum router. Developed at Tsinghau University in China, the router makes a quantum photon from two separate photons in different polarized states. At this point, things start to get a little, well, mind-bending, as they are wont to do in the quantum world. The net result, however, is one qubit of data being "routed" at a time. While this won't be powering any serious networks anytime soon, the all important proof of concept is there, and we imagine, in a parallel universe simultaneously.

Researchers capture a single atom’s shadow, has implications for quantum computers

Researchers capture a single atom's shadow, has implications for quantum computers

A very small atom can cast a very large shadow. Well, not literally, but figuratively. Researchers at Griffith University have managed to snap the first image of a single atom's shadow and, while the dark spot may be physically small, the implications for the field of quantum computing are huge. The team of scientists blasted a Ytterbium atom suspended in air with a laser beam. Using a Fresnel lens, they were able to snap a photograph of the dark spot left in the atom's wake as the laser passed over it. The practical applications could improve the efficiency of quantum computers, where light is often used to transfer information. Since atoms have well understood light absorption properties, predictions can be made about the depth of a shadow cast, improving communication between the individual atoms performing calculations. The research could even be applied to seemingly mundane and established fields like X-Ray imaging, by enabling us to find the proper intensity levels to produce a quality image while minimizing damage to cells. For more info, check out the current issue of Nature.

CCNY, UC Berkeley develop lasers that could rewrite quantum chips, spin those atoms right round

CCNY, UC Berkeley develop lasers that could rewrite quantum chips, spin those atoms right roundComputers are normally limited by the fixed nature of their chipsets: once the silicon is out of the factory, its capabilities are forever locked in. The City College of New York and University of California Berkeley have jointly developed a technique that could break chips free of these prisons and speed along quantum computing. They found that hitting gallium arsenide with a laser light pattern aligns the spins of the atoms under the rays, creating a spintronic circuit that can re-map at a moment's notice. The laser could be vital to quantum computers, which can depend heavily or exclusively on spintronics to work: a simple shine could get electrons storing a much wider range of numbers and consequently handling many more calculations at once. Research is only just now becoming public, however; even though gallium arsenide is common in modern technology, we'll need to be patient before we find quantum PCs at the local big-box retail chain. Despite this, we could still be looking at an early step in a shift from computers with many single-purpose components to the abstracted, all-powerful quantum machines we've held in our science fiction dreams.

Researchers take nanowire transistors vertical, double up on density

researchers-take-nanowire-transistors-vertical

3D silicon is all the rage, and now nanowire transistors have further potential to keep Moore's Law on life support. Researchers at A*STAR have found a way to double the number of transistors on a chip by placing the atomic-scale wires vertically, rather than in the run-of-the-mill planar mode, creating two "wrap-around gates" that put a pair of transistors on a single nanowire. In the future, the tech could be merged with tunnel field effect transistors -- which use dissimilar semiconductor materials -- to create a markedly denser design. That combo would also burn a miniscule percentage of the power required conventionally, according to the scientists, making it useful for low-powered processors, logic boards and non-volatile memory, for starters. So, a certain Intel founder might keep being right after all, at least for a few years more.

NIST researchers store two images in a cloud of gas, open new possibilities for quantum memory

Physicists have already been able to store a single image in a cloud of rubidium gas, but researchers from the National Institute of Standards and Technology in Maryland have now made a new breakthrough that could open up some new possibilities for quantum memory. As Technology Review's Physics arXiv blog reports, they've managed to store two sequential images in the cloud (not to be confused with "the cloud") and retrieve (or view) them at different times with about 90 percent accuracy -- something that could technically be called a movie. That was done using much the same technique that allows a single image to be stored in the gas, although storing multiple images apparently has the side effect of causing them to be retrieved in the reverse order of how they went in. As TR notes, however, even with that quirk, this new method could give rubidium gas a leg up over something like holographic storage, which has only been able to store and retrieve multiple images at the same time.

Scientists create the first universal quantum network, are scared to restart the router

Scientists create the first universal quantum network, are scared to restart the routerWe all know that most networks are, well, just not "quantumy" enough. Good news, then, that German boffins at the Max Planck Institute of Quantum Optics have created the first "universal quantum network." We've been hearing about plain old quantum computing since the first qubit was sent, but now we have to get our tiny minds around the idea of a quantum internet too. Data was sent using single rubidium atoms in reflective optical cavities and single photons emitted over optical fiber. Given that data was only successfully transmitted 0.2% of the time, and the network spanned just 21 meters, a complex LAN with multiple nodes is a way off just yet, but the proof of concept is there. If that concept is the early '90s internet that is.

Flawed diamonds are perfect ingredients for quantum computing, just add time travel

Flawed diamonds are perfect ingredients for quantum computing, just add time travel
Ready to suspend your brain cells in a superposition of disbelief? Good, because the latest news published in Nature is that diamonds are a quantum computer's best friend -- particularly if they're flawed. An international team of scientists sought out sub-atomic impurities in a 1mm-thick fragment of over-priced carbon and used these as qubits to perform successful calculations. A "rogue" nitrogen nucleus provided one qubit, while a free electron became a second. Unlike previous attempts at solid-state quantum computing, this new effort used an extra technique to protect the system from decoherence errors: microwave pulses were fired at the electron qubit to "time-reverse" inconsistencies in its spinning motion. Don't fully get it? Us neither. In any case, it probably won't stop jewellers tut-tutting to themselves.
