Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

A new ultra-fast monitoring system reveals that quantum computer qubits can change from stable to unstable in mere milliseconds.

When Richard Feynman first conceived of quantum computers in the 1980s, he believed they should primarily investigate quantum phenomena. So that’s what a group of chemists did: they used quantum ...

Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are practically impossible to solve. Quantum computers threaten to flip that ...

The breakthrough addresses concerns that powerful quantum computers could eventually crack encryption standards to leave vulnerable financial systems, government communications, health data and media.

The commonly used RSA encryption algorithm can now be cracked by a quantum computer with only 100,000 qubits, but the technical challenges to building such a machine remain numerous ...

Quantum computers have become the latest canvas for humanity’s oldest fantasy: escaping death. Startups, futurists, and speculative essays now suggest that machines built to manipulate qubits could ...

Jacob Benestad in front of an experimental setup in the laboratory at the Niels Bohr Institute, University of Copenhagen. This setup is similar to the one used during the group's experiments at the ...

The JVG algorithm factors RSA and ECC keys using fewer quantum resources than Shor’s algorithm, accelerating the time needed ...
