Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a ...

It can be difficult to understand quantum mechanics. That's okay, because, in the early days of the Internet, few could understand how that worked. Now, new developments in quantum communication may ...

A major breakthrough in quantum technology was achieved in October 2024: the first-ever quantum satellite communication link between China and South Africa. The connection spanned a remarkable 12,900 ...

A small quantum satellite created a secure link between ground stations in China and South Africa, sharing quantum-encrypted data over a record distance of 12,900 kilometres. Similar microsatellites ...

"Our nonlinear system transmits quantum information with 94% fidelity, compared to the theoretical limit of 33% on systems using linear optical components," said Kejie Fang, an Illinois professor of ...

The world’s longest quantum communications link has been set up between China and South Africa, spanning a record-breaking 12,900 km (8,015 miles). The connection takes advantage of quantum physics ...

The Defense Advanced Research Projects Agency is angling to lay the groundwork for a computational network that can integrate both traditional and quantum-powered systems ahead of further ...

If the Pentagon is to harness the promise of quantum-powered devices, it needs ways to connect them to today's data networks. But networking has been the “black sheep” of quantum research, says the ...

Quantum computing is getting a lot of attention lately — deservedly so. It’s hard not to get excited about the new capabilities that quantum computing could bring. This new generation of computers ...
