The race to build a quantum internet has shifted from theory to engineering, as researchers learn how to send fragile quantum ...

Quantum networking has long sounded like science fiction, but a series of recent lab results is turning it into a practical engineering problem. Researchers are now pushing fragile quantum states ...

One of the most complex quantum networks built to date would allow 18 people to communicate securely thanks to the power of quantum physics. The researchers behind the work say it offers a practical ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...

In a first-of-its-kind experiment, engineers at the University of Pennsylvania brought quantum networking out of the lab and onto commercial fiber-optic cables using the same Internet Protocol (IP) ...
