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 ...

A device smaller than a grain of dust may help unlock the kind of quantum computers people have only dreamed about. Built on ...

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 ...

While today's AI chips are electronic and rely on electricity to perform calculations, the new chip is photonic, meaning it uses beams of light instead. Described in Nature Photonics, the chip ...

Scientists have turned a long-standing sci‑fi idea into working hardware, using pure light to move data wirelessly through the air instead of relying on radio waves or copper traces. The result is a ...

Slight temperature changes, imperceptible manufacturing imperfections, and heat generated by their own components can completely ruin an entire quantum quantum system-on-chip. Silicon photonics could ...

As programmable photonics use light instead of electrons to transmit and process signals, they promise faster, more ...
