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 ...

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 ...

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 ...

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 ...

Cisco has launched its first universal quantum switch, calling it a foundational technology for building a scalable quantum ...

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 ...

Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography ...
