John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the ...

A 91-qubit superconducting processor manages to simulate quantum chaos with unprecedented precision despite experimental ...

Another major quantum computing record has been broken, and by a considerable margin: physicists have now built an array containing 6,100 qubits, the largest of its type and way above the thousand or ...

Quantum chaos describes chaotic classical dynamical systems in terms of quantum theory, but simulations of these systems are limited by computational resources. However, one team seems to have found a ...

Quantum computing has long been constrained by the messy reality of controlling fragile qubits with bulky, power-hungry ...

There are lots of quantum computing start-ups, but IBM, America's first tech company, has led the pack since the 1970s, and is set to continue that dominance through 2026 and beyond.

Unlike conventional phases of matter, the so-called non-equilibrium quantum phases are defined by their dynamical and time-evolving properties — a behavior that cannot be captured by traditional ...

Quantum computing has great potential , but its main unit, the qubit, is beset by inherent stability problems. However, this new study might change that.

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

Can quantum computing save us from 500 missiles attacking simultaneously? Perhaps ... and it has a far better shot than ...

IBM (NYSE:IBM) said it can run a vital quantum computing algorithm on commonly available chips from Advanced Micro Devices (NASDAQ:AMD), Reuters reported. Jay Gambetta, the IBM vice president running ...
