Russia has quietly vaulted into the front rank of quantum powers with a neutral-atom machine that combines a 72-qubit scale ...

Physicists have created a Schrödinger's cat state at unusually hot temperatures, and it could be a major step toward the development of practical quantum computers. Schrödinger's cat states exist in ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems.

As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

Scientists have used high-performance computing at large scales to analyze a quantum photonics experiment. In specific terms, this involved the tomographic reconstruction of experimental data from a ...

Rapid advances in the kind of problems that quantum computers can tackle suggest that they are closer than ever to becoming ...

This device is known as a Josephson junction. It’s the foundational building block of quantum computers and advances of it ...

Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not ...

A quantum internet would essentially be unhackable. In the future, sensitive information—financial or national security data, for instance, as opposed to memes and cat pictures—would travel through ...

Scientists at Paderborn University have for the first time used high-performance computing (on the right in the picture the Paderborn supercomputer Noctua) to analyse a quantum photonics experiment on ...
