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 ...

Researchers have developed a new optical computing material from photon avalanching nanoparticles. A research team co-led by Lawrence Berkeley National Laboratory (Berkeley Lab), Columbia University, ...

Are you ready to test your brain with a fun and tricky optical illusion? Here’s a challenge that might leave you scratching your head: three computers and three computer mice are all tangled up ...

Digital point-and-shoot cameras as well as consumer and prosumer video camcorders have optical zoom, but they also have digital zoom. At the telephoto side of the camera, the computer takes over ...

Given that the basic computing element of a computer is a transistor — an electronic switching element — and that great progress has been made in all-optical switching and logic, there is an ...

Japanese researchers have helped develop an optical quantum computer that has the potential to drastically reduce the size of the next-generation computer and do even faster calculations. Because ...

Leading efforts in fields such as optical physics could stymie US export controls designed to stifle the country’s microchip ...
