Superconducting vortices moonlight as controllable qubits, turning a disruption into a resource

May 22, 2026 Vortices in superconductors have so far been considered a disruption, as they can impair the superconducting properties. Researchers at the Karlsruhe Institute of Technology (KIT) have proved in experiments that magnetic vortices can be used as controllable quantum systems in certain materials. This means that a previously unwanted phenomenon is becoming a

‘Designer’ superconducting diamond: Researchers uncover path to multi-modality quantum chips

May 22, 2026 Diamond is extremely valuable to science and technology not for its sparkle but for its extreme hardness, high thermal conductivity, transparency to a large fraction of the light spectrum, and a host of other exceptional properties. Two decades ago, scientists discovered another advantage: under the right conditions, diamond can become a superconductor—allowing

Diamond quantum sensor could reveal elusive altermagnets

May 29, 2026 For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but are increasingly prized for their technological potential. A third category discovered within the last decade may combine

Scientists identify the origin of noise in spin qubit quantum processors

June 6, 2026 A spin qubit, in which quantum information is encoded in the spin state of an electron, is one of the most promising platforms for quantum computing. Spin qubits exhibit long coherence times and are compatible with advanced semiconductor manufacturing technologies. The leading implementation of spin qubits involves confined electrons inside quantum dots,

Predictive surrogates could cut quantum computing measurement overhead by more than 99.97%

June 6, 2026 Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of outperforming classical computers on some tasks. Despite their potential, the use of these systems remains very limited, due to their high cost and other challenges that have so far prevented their large-scale fabrication. Read the full article →
