Energy-level quantization and single-photon control of phase slips in YBa2Cu3O7–x nanowires

Abstract

Superconducting nanowires with quantum phase slips are promising candidates for future quantum technologies. Here, Lyatti et al. report evidence for energy-level quantization and single photon control of phase slips in ultra-thin YBa2Cu3O7-x nanowires, promising for quantum sensing and computing.
