Researchers at the University of Massachusetts Amherst have built a chip-scale laser stable enough to control a trapped-ion ...

Computers that use light instead of circuits to run calculations may sound like a plot point from a Star Trek episode, but researchers have been working on this novel approach to computing for years.

The (above) figure shows how light is focused into a tiny processing unit, allowing vast strings of computational information to be transferred without the use of energy-intensive circuitry. The other ...

CMOS-built optical phase modulators shrink laser control hardware and power use for trapped atom quantum computers, enabling larger stable qubit arrays at work. (Nanowerk News) Researchers have made a ...

Caltech researchers cut quantum computing qubit estimates by 100x, putting encryption-breaking quantum computers theoretically within reach this decade.

In a recent study published in Nature Photonics, a research team led by Lawrence Berkeley National Laboratory (Berkeley Lab), Columbia University, and Universidad Autónoma de Madrid developed a new ...
