Superconducting qubits—bits of quantum information—have been widely considered a promising technology for moving quantum computing forward. But there's still much work to be done before they can be ...

Quantum computing is a largely theoretical, ultimately expensive proposition for high-level computation. However, new ...

The day when a quantum computer manages to break common encryption, or Q-Day, is fast approaching, and the world is not close ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

A quantum computer assists an AI model with calculations that would take weeks to figure out with a normal computer.

Two independent research teams have each demonstrated collisional quantum gates using fermionic atoms: a long-sought ...

Shares of IonQ surged 20% on April 14 to $35.76 after the quantum computing company landed a U.S. defense research contract, ...

Quantum hardware and software are advancing rapidly – and our online encryption systems need to change to stay ahead.

Pushing against years of scepticism, an analysis suggests quantum computers may offer real advantages for running machine ...

As US defence research agency DARPA starts a programme to upend the dominant quantum computing architecture it says will fail ...

New research suggests quantum computers capable of breaking internet encryption may arrive sooner than expected—with AI ...
