PORTLAND, Ore. Photonic microchips were enabled Sunday (Feb. 15) by Cornell University's announcement at the American Association for the Advancement of Science (AAAS) in Seattle, of having fabricated ...

Researchers at MIT, Harvard and the Vienna University of Technology have developed a proof-of-concept optical switch that can be controlled by a single photon and is the equivalent of a transistor in ...

Ars has been covering quantum computing developments for a while now. Quantum computing, instead of using bits that are definitely one or zero, relies on qubits that hold a superposition of both one ...

Optical computers, possibly using glass-fiber transmission lines and quantum-electronic storage elements, are now under consideration, according to L.C. Clapp of the ...

Optical multiplication: a new technique for combining light signals could give optical computers a boost. (Courtesy: iStock/7io) Researchers in Russia and the UK have proposed a new and simple way to ...

A research team has developed an optical computing system for AI and machine learning that not only mitigates the noise inherent to optical computing but actually uses some of it as input to help ...

One of the attractive features of early optical computer mice was their lack of moving parts. The idea is that fewer moving parts translate into less mechanical wear and longer life. But even though ...

Contrary to current trends, the CPU may get bigger in the future. Yes, the size of CPUs are larger today than they were in the past, but they also pack in more transistors. The future may involve ...

A machine made from a 5-kilometre-long fibre optic cable coiled into a box a few metres across could give quantum computers a run for their money on certain tasks. The device, which performs ...

We always hear that future computers will use optical technology. But what will that look like for a general-purpose computer? German researchers explain it in a recent scientific paper. Although the ...
