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 ...

A computer in which all internal circuits use light instead of electricity. Long predicted, an all-optical computer is not expected for some time as there are hurdles to overcome. However, there are ...

Researchers have successfully created an optical transistor from a single molecule. This has brought them one step closer to an optical computer. ETH Zurich researchers have successfully created an ...

As previously mentioned about one week ago, a startup company called Optalysis is trying to invent a fully-optical computer that would be aimed at many of the same tasks for which GPUs are currently ...

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 ...

Modular optical computer chip allows stackable swappable functions By Michael Irving June 20, 2022 MIT engineers have developed a new modular computer chip that uses flashes of light to communicate ...

NTT and OptQC have signed a collaboration agreement to develop scalable and highly reliable optical quantum computers, aiming to achieve one million qubits by ...

When the German computer pioneer Konrad Zuse built the world’s first programmable computer in war time Berlin, it performed floating point arithmetic at a clock speed of between 5 and 10 Hz. The ...

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 ...
