Clavina combines linear and nonlinear quantum operations, advancing light-based quantum computing and error correction.

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a useful quantum machine. It aims to be the first. The machine that could ...

William Andregg ushers me into the cluttered workshop of his startup Fathom Computing and gently lifts the lid from a bulky black box. Inside, green light glows faintly from a collection of lenses, ...

A computer that uses light rather than digital switches for calculations could help reduce the energy demands of artificial intelligence (AI), according to a new study. The scientists who invented the ...

A new type of computer that uses light rather than electricity could perform calculations faster, using less energy and less space. Computer chips are made up of millions or billions of logic gates.
