Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In their experiment, photons drift sideways in perfectly defined, quantized steps ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

Google on Friday unveiled its plan for its Chrome browser to secure HTTPS certificates against quantum computer attacks without breaking the Internet.

Ethereum co-founder Vitalik Buterin laid out a quantum resistance roadmap targeting four key vulnerabilities in the network’s cryptography.

Duplicating the information held in quantum computers was thought to be impossible thanks to the no-cloning theorem, but researchers have now found a workaround ...
