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

Phys · · 648 words · By Sabine Fodi
Scientific Research Advancement Quantum Technology Innovation

Researchers at the Karlsruhe Institute of Technology have demonstrated that magnetic vortices in certain superconducting thin films can function as controllable qubits. The study, published in Nature, suggests that these previously disruptive phenomena could be utilized for quantum computing and high-sensitivity sensor systems.
