Quantum computing has long promised to crack problems that defeat even the fastest supercomputers, but the hardware has struggled to scale beyond fragile laboratory prototypes. A new generation of ...

Artificial intelligence is consuming enormous amounts of energy, but researchers at the University of Florida have built a chip that could change everything by using light instead of electricity for a ...

A new semiconductor chip fabricates miniature lenses on the chip to perform calculations using light instead of electricity, greatly increasing the power efficiency and reducing the computational run ...

Researchers from the University of Twente and Harvard University have developed a new way to generate ultraviolet (UV) light on a photonic chip at power levels high enough for real-world use. For the ...

Over the past several decades, researchers have been making rapid progress in harnessing light to enable all sorts of scientific and industrial applications. From creating stupendously accurate clocks ...
