Penn engineers have taken quantum networking from the lab to Verizon’s live fiber network, using a silicon “Q-chip” that speaks the same Internet Protocol as the modern web. The system pairs classical ...

The race to build a quantum internet has shifted from theory to engineering, as researchers learn how to send fragile quantum signals through the same glass fibers that already carry Netflix streams ...

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 ...

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 ...
