Physicists Unveil First Quantum Interconnect

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

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.

The Toil Toward Quantum Computers Just Turned Into a Sprint

Posted by in categories: biotech/medical, computing, electronics, quantum physics, supercomputing

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:

Reprogrammable optic chip has complete flexibility in processing of photons and is a pathway to quantum computing

Posted by in categories: biotech/medical, computing, electronics, quantum physics

Researchers from the University of Bristol in the UK and Nippon Telegraph and Telephone (NTT) in Japan, have developing an optical chip that can process photons in an infinite number of ways.

It’s a major step forward in creating a quantum computer to solve problems such as designing new drugs, superfast database searches, and performing otherwise intractable mathematics that aren’t possible for super computers.

The fully reprogrammable chip brings together a multitude of existing quantum experiments and can realise a plethora of future protocols that have not even been conceived yet, marking a new era of research for quantum scientists and engineers at the cutting edge of quantum technologies.
