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 ...

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 ...

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 ...

Silicon Valley technology titans IBM Corp. and Cisco Systems Inc. are looking beyond artificial intelligence to the next big thing: quantum computing. Today they announced plans to collaborate on a ...

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 ...
