Researchers at the Karlsruhe Institute of Technology (KIT) have turned a long-standing problem in superconductivity into a promising new resource for quantum computing. Magnetic vortices — tiny whirlpools of magnetic field that usually disrupt superconducting materials — have been shown to behave as controllable quantum states.

By adapting an algorithm from the 1980s to mathematical objects called tensor networks, researchers at the Flatiron Institute show that classical computers can tackle a class of problems previously claimed to be solvable only by quantum computers

Quantum mechanics’ famous measurement problem — illustrated by Schrödinger’s cat — may be one step closer to an experimental answer. Using the ultra-sensitive XENONnT dark matter detector deep underground in Italy, an international team has placed the strongest constraints yet on “collapse models,” theories proposing that quantum superpositions spontaneously collapse due to interactions with a noise field or gravity.

A new approach to looking at solids provides theoretical limits on some of their properties

A new method for precisely moving columns of individual atoms within a material could give rise to exotic quantum properties

Researchers at The University of Manchester’s National Graphene Institute have shown that electrons in ultra-clean graphene can be steered with high precision while keeping their spin information intact, a key requirement for future low power electronics and quantum devices.

Electrons can arrange into crystalline patterns that accumulate defects as they melt; controlling the degree of melting may advance superconductors and artificial neurons

Good vibrations for quantum communications

The latest study on an electron-on-neon qubit, invented at Argonne, shows its strong potential to scale quantum information processing.

Researchers at the University of Alicante (UA) have developed a highly precise method for measuring distances at the nanometre scale at room temperature, opening up new avenues in molecular electronics research.

Researchers at the University of Texas at Austin and the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg found that electronic fluctuations can dynamically bridge vibrations that symmetry would normally keep separate.

Researchers at the University of Oxford have demonstrated a new type of quantum interaction using a single trapped ion.
