Analysis pokes holes in protocol that underpins Microsoft’s claim to have created the first topological qubits.

Researchers observed a long-predicted fractal energy pattern in twisted carbon materials, confirming quantum theories.

In this episode of the Physics World Weekly podcast, we explore how computational physics is being used to develop new ...

Many physicists and engineers have recently been trying to demonstrate the potential of quantum computers for tackling some ...

Working at nanoscale dimensions, billionths of a meter in size, a team of scientists revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new ...

UC Santa Barbara researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop ...

"The long-term vision is, you could potentially build quantum machines or devices that use these three or even all four of these properties: photons to transfer information, electrons to process ...

Quantum computing could be worth $850 billion by 2040. Alphabet is making big strides in this space with its Willow processor. IBM is a major quantum computing player, and its shares are ...

But quantum computers, when they come, promise to increase that power for certain types of computations to levels no binary-based device could conceivably reach. Quantum computers use a different ...

It cannot do any useful work until it somehow is extended with many more qubits, known in technical terms as "scaling" the device. The topological qubit is unlike other quantum devices because of ...

Some estimates say a quantum device capable of breaking current encryption would require 10,000 qubits, while others say millions would be needed. Today’s systems have a few hundred at most.
