Breakthrough from a team led by Jacob Covey, associate professor in the University of Chicago’s Pritzker School of Molecular Engineering and Department of Physics, turns helium-3’s low mass into a quantum resource

The new Finnish startup is disrupting the ways of controlling large-scale quantum computers by delivering a completely new class of electronic devices – superconducting transistors. These novel devices combine the computational power of transistors with the ultra-low power dissipation of superconductors. S-Transistors is developing first-of-its-kind quantum motherboards that will provide energy- and cost-efficient orchestration of cryogenic quantum computers at scale. Espoo,

A line of orange atoms is depicted in blue laser tweezers. @ California Institute of Technology Physicists use advanced quantum technologies to test decades-old theory predictions When different materials transition from one phase to another, such as water coming to a boil or a magnet losing its ability to attract metals, something remarkable can happen: They begin to behave identically, following the same mathematical rules. "Physicists call this trait universality—the messy

In this illustration, photons hit a strip of superconducting wire, disrupting the electric current and registering an electric pulse. Each pulse tells researchers about the light that has hit the detector, which is beneficial for applications like biomedical imaging and astronomy.

An AI-generated illustration depciting the Kondo effect. Conducting electrons in a metal are shown interacting with the spin of an embedded magnetic atom impurity. Credit: AI-generated artwork by Linqing Peng A team of scientists from Caltech and Yale University has shown for the first time how to accurately quantify an important quantum phenomenon in metals, called the Kondo effect, for specific real materials. Unlike previous approaches, which for decades have relied on sim

Researchers at the University of Cambridge have identified a stricter criterion for when quantum computers can outperform classical machines. Magic states, special qubit configurations required for universal quantum computation, are necessary but not always sufficient. Many states previously regarded as useful magic can still be simulated efficiently on classical computers. The team used the Kirkwood–Dirac distribution, a 1945 quasi-probability framework associated with Paul
