A European research team has demonstrated quantum key distribution over 303 kilometers of live Swedish telecom fiber — nearly doubling the previous record for the country's deployed infrastructure — ...

A team of researchers led by PAN Jianwei, ZHANG Qiang, and BAO Xiaohui from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), along with other ...

Reliable quantum communication over hundreds of kilometers is a daunting yet necessary requirement for a quantum internet. To overcome photon loss, the deployment of quantum repeater stations between ...

Polychromatic resources have transformed classical communication networks by boosting rate and scalability; quantum communication networks are reaching a similar inflection point. Here, we report a ...

As quantum computers continue to advance, many of today’s encryption systems face the risk of becoming obsolete. A powerful alternative—quantum cryptography—offers security based on the laws of ...

We may never beam ourselves off the planet. But quantum teleportation is poised to bring about a new era of computing—and revolutionize our understanding of the subatomic world. This composite photo ...
