As artificial intelligence grows more powerful, so does its appetite for speed and energy. The quest for faster, smarter systems has driven researchers to an unlikely ally—light itself. A new study by ...

Two new studies suggest optical computing, which uses light to process data, is much closer to becoming a faster, more energy-efficient alternative to conventional systems. One study used an optical ...

Researchers developed a faster, more stable way to simulate the swirling electric fields inside industrial plasmas -- the kind used to make microchips and coat materials. The improved method could ...

SAN FRANCISCO (Reuters) -Silicon Valley startup Lightmatter revealed on Wednesday it had developed a new type of computer chip that could both speed up artificial intelligence work and use less ...
