Performing complex algorithms on quantum computers will eventually require access to tens of thousands of hardware qubits. For most of the technologies being developed, this creates a problem: It’s ...

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 ...

Caught in a traffic jam with the internet, quantum teleportation persists. An experiment demonstrating that the two can share an optical fibre may point towards an easier way to build an unhackable ...
