A Russian research group at the Moscow Institute of Physics and Technology has demonstrated a superconductor feature known as Abrikosov vortices exists in non-superconducting metal when in contact with a superconductor. The nexus for quantum computers and this finding lays in the key property of superconductors: Quantum coherence. This “macroscopic quantum coherence of superconductors” may be harnessed to enable qubits.
