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) ...

Quantum teleportation has quietly moved from thought experiment to working network demo, with researchers now shuttling quantum information between pulses of light traveling on ordinary fiber. Instead ...

It's one thing to dream up a quantum internet that could send hacker-proof information around the world via photons superimposed in different quantum states. It's quite another to physically show it's ...

As long as there's been an internet, there's been a way to hack it. Scientists have spent decades imagining a different kind of network, one where the laws of physics make eavesdropping physically ...
