For more than 60 years, Bell's theorem has been the gold standard for demonstrating that quantum mechanics defies the rules ...

A quantum internet would essentially be unhackable. In the future, sensitive information—financial or national security data, for instance, as opposed to memes and cat pictures—would travel through ...

A quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered ...

With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to arXiv.org. Another prevalent form of encryption, RSA–2048, would require 100 ...

Researchers have demonstrated a network connection between quantum processors over metropolitan distances. Their result marks a key advance from early research networks in the lab towards a future ...

A programmable photonic circuit has been developed that can execute various quantum algorithms and is potentially highly scalable. This device could pave the way for large-scale quantum computers ...

The day when a quantum computer can crack commonly used forms of encryption is drawing closer. The world isn’t prepared, ...

Cisco Systems Inc. is backing a startup that has successfully deployed a next-generation network that makes use of quantum entanglement, paving the way for the creation of a “quantum internet.” The ...

Researchers at Harvard University have demonstrated the longest distance fibre transmission between quantum nodes to date, highlighting that the idea of a quantum internet isn't just fanciful thinking ...

Scientists tested a live quantum internet between three locations across New York, inching closer to an unhackable internet.

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) ...
