Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...

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

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

Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

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 ...

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 ...

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 ...

Researchers at the quantum computing firm Quantinuum used a new Helios-1 quantum computer to simulate a mathematical model that has long been used to study superconductivity. These simulations are not ...

Teleportation is a reality in 2025 — well, at least for quantum computers. In February 2025, Oxford University demonstrated the teleportation of quantum data from one independent quantum processor to ...
