Nanotubes open new path toward quantum information technologies

“Beyond implementation of quantum communication technologies, nanotube-based single photon sources could enable transformative quantum technologies including ultra-sensitive absorption measurements, sub-diffraction imaging, and linear quantum computing. The material has potential for photonic, plasmonic, optoelectronic, and quantum information science applications…”


In optical communication, critical information ranging from a credit card number to national security data is transmitted in streams of laser pulses. However, the information transmitted in this manner can be stolen by splitting out a few photons (the quantum of light) of the laser pulse. This type of eavesdropping could be prevented by encoding bits of information on quantum mechanical states (e.g. polarization state) of single photons. The ability to generate single photons on demand holds the key to realization of such a communication scheme.

By demonstrating that incorporation of pristine into a silicon dioxide (SiO2) matrix could lead to creation of solitary oxygen dopant state capable of fluctuation-free, room-temperature single , Los Alamos researchers revealed a new path toward on-demand single photon generation. Nature Nanotechnology published their findings.

Why’s IBM Investing $3 Billion In Quantum Computing & Synth Brains? Trillion Dollar Humanoid Market

1. Silicon technology has taken humanity a long way forward from 1947 when the first transistor was invented by the Nobel prize winners Shockley, Bardeen & Brattain.

2. From smart mobile telephones we rely on to the sophisticated satellite navigation systems guiding our cars, a lot of techno-magic we see around us is a result of our ability to scale silicon-tech that turns hitherto science fiction into everyday reality at affordable prices.

3. All the Nobel laureates, scientists and engineers we liaise with at Quantum Innovation Labs http://QiLabs.net collectively realise the end of the silicon-scaling era is coming to end as the Moore’s Law era for Silicon-based computers finally concludes.

Intel pledges $50M in quantum computing push to solve big problems

Intel today announced plans to invest $50 million over the next ten years as part of a quantum computing push to help solve problems such as “large-scale financial analysis and more effective drug development.”

But despite the ambitions and huge cost of the project, company vice president Mike Mayberry admits that “a fully functioning quantum computer is at least a dozen years away.”

The money will be channeled through QuTech, the quantum research institute of Delft University of Technology, and TNO, with Intel additionally pledging to commit its own “engineering resources” to the collaborative effort.

Physicists Unveil First Quantum Interconnect

One of the unsung workhorses of modern technology is the humble interconnect. This is essentially a wire or set of wires that link one part of an electronic system to another. In ordinary silicon chips, interconnect can take up most of the area of a chip; and the speed and efficiency with which information can travel along these interconnects, is a major limiting factor in computing performance.

So it’s no wonder that physicists and engineers are creating new generations of interconnect that will become the backbone of information processing machines of the future.

Austrian Scientists Develop Ghostly Superposed Quantum Circuits for Faster Quantum Computing

Scientists at the University of Vienna and the Austrian Academy of Sciences have developed a new quantum computing technique in which operations occur without a well-defined order. The new technique accomplished a task more efficiently than a standard quantum computer, and could open the way to faster quantum computing.

The Toil Toward Quantum Computers Just Turned Into a Sprint

A new optical chip that can process photons in a dizzying number of infinite ways has been developed by two research teams. Researchers from the University of Bristol in the UK and Nippon Telegraph and Telephone in Japan (NTT) are behind the breakthrough in quantum computing. The means to solve daunting problems such as the ability to design new life-saving drugs; perform advanced calculations that are a step or two beyond even supercomputers; and analyze weather patterns for more accurate forecasting has just received a major boost.

A group of researchers have pulled off a staggering feat; they’ve developed a silicon-based optical chip that is fully reprogrammable and can process photons in every way imaginable and then some, reports Phys.org.

Prof. Jeremy O’Brien, the Director of the Centre for Quantum Photonics at Bristol University where researchers masterminded the development of the chip, said:
