Fraunhofer ILT in Aachen has developed a highly complex laser-optical system for a quantum computer currently under construction at the 5th Institute of Physics at the University of Stuttgart. This ...

The computing world is on the cusp of a transformative leap forward, as researchers at the California Institute of Technology (Caltech) have unveiled an all-optical computer capable of achieving clock ...

Computers that use light instead of circuits to run calculations may sound like a plot point from a Star Trek episode, but researchers have been working on this novel approach to computing for years.

The idea of optical computing—the use of photons instead of electrons to perform computational operations—has been around for decades. However, interest has resurged in recent years; the potential for ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

Although computers are overwhelmingly digital today, there’s a good point to be made that analog computers are the more efficient approach for specific applications. The authors behind a recent paper ...

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 ...

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 ...
