A team of physicists has taken a step toward making the essential building block of quantum computers out of pure light. Their advance has to do with logic gates that perform operations on input data to create new outputs.
The world only quantum computer maker says its upgraded chip is 15 times faster than ordinary computers, but experts doubt the comparison is a fair test.
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.
Cryptographers are working on new encryption methods able to protect today’s Internet communications from future quantum computers that can be able to break today’s cryptography techniques. The researchers have developed upgrades to the Internet’s core encryption protocol that will prevent quantum computer users from intercepting Internet communications.
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.
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:
Professor Kheifets and Dr. Igor Ivanov, from the ANU Research School of Physics and Engineering, and An international team of scientists studying ultrafast physics have solved a mystery of quantum mechanics, and found that quantum tunneling is an instantaneous process.
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.
The microprocessor inside a computer is a single multipurpose chip that has revolutionised people’s life, allowing them to use one machine to surf the web, check emails and keep track of finances.
Now, researchers from the University of Bristol in the UK and Nippon Telegraph and Telephone (NTT) in Japan, have pulled off the same feat for light in the quantum world by developing an optical chip that can process photons in an infinite number of ways.
I’m a firm believer that technology can take us to unimaginable places, from both a physical and a mental standpoint. Technological progress is oftentimes cha.
