Scientists at Harvard University have shown how ultra-cold atoms can be used to freeze and control light to form the "core" – or central processing unit – of an optical computer. Optical ...

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 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 ...

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 ...

William Andregg ushers me into the cluttered workshop of his startup Fathom Computing and gently lifts the lid from a bulky black box. Inside, green light glows faintly from a collection of lenses, ...

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 ...

Optalysys optical processing systems will “turbo-charge” existing computers by performing processor-intensive tasks at much faster rates and with a significant reduction in energy consumption. The ...

Researchers at the University of Bristol in the UK have made a prototype optical quantum computer chip and used it to perform a mathematical calculation for the first time. The device consists of tiny ...

WASHINGTON--(BUSINESS WIRE)--Researchers have demonstrated a new technique that can store more optical data in a smaller space than was previously possible on-chip. This technique improves upon the ...

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 ...
