Quantum dot–based time-bin QKD achieves stable, long-distance secure communication with practical performance.

The ability to send quantum information securely, known as quantum key distribution, is one of the most practical (if difficult) applications of quantum science. A new study demonstrates the ...

IonQ deployed what it claims to be the largest and most complex quantum key distribution (QKD) network in Europe. The initiative came out of a project with Romanian institutions, including the ...

Quantum communication could enable uncrackable transfer of information, but most approaches rely on trusted devices. Researchers have now demonstrated that a new method that does away with this ...
