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

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 ...

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.

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

An international team of researchers has synthesized a carbon chain molecule with a never-before-seen electronic twist and ...

An international team of scientists from IBM, The University of Manchester, Oxford University, ETH Zurich, EPFL and the University of Regensburg have created and characterized a molecule unlike any ...

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

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 ...
