Optical computers light up the horizon

Since their invention, computers have become faster and faster, as a result of our ability to increase the number of transistors on a processor chip.

Lens trick doubles odds for quantum interaction

It's not easy to bounce a single particle of light off a single atom that is less than a billionth of a metre wide. However, researchers at the Centre for Quantum Technologies at the National University of Singapore have ...

Atomic cousins team up in early quantum networking node

Large-scale quantum computers, which are an active pursuit of many university labs and tech giants, remain years away. But that hasn't stopped some scientists from thinking ahead, to a time when quantum computers might be ...

Syncing data center computers at the speed of light

When several computers need to work together, as when calculating in parallel on several parts of a single large problem or managing a large database, they need to keep in step. These situations are particularly common in ...

More reliable way to produce single photons

Physicists at the University of Bath have developed a technique to more reliably produce single photons that can be imprinted with quantum information.

Quantum computing a step closer to reality

Physicists at the Australian National University (ANU) have brought quantum computing a step closer to reality by stopping light in a new experiment.
