A new room-temperature quantum device developed at Stanford uses twisted light and advanced materials to link photons and electrons. Modern quantum computers are typically large, costly systems that ...

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending ...

The Air Force Research Laboratory has awarded BlackSky a contract worth up to $99 million to develop a large optical imaging payload intended for future space-based intelligence systems. The contract, ...

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

Recent maneuvers by Russian satellites near European geostationary communications platforms have highlighted the risks to unencrypted command links and data transmissions. These developments emphasize ...

Big quote: Light, not silicon, could someday define how artificial intelligence stores and recalls its knowledge. That's the idea that recently surfaced when John Carmack – the engineer known for his ...
