High cooperativity coupling to nuclear spins on a circuit quantum electrodynamics architecture

Abstract

Superconducting hybrid systems are becoming an increasingly important platform to conduct investigations in the field of quantum information processing. Here, the authors report a highly cooperative coupling between the nuclear spin of an Yb(III) molecular complex with a superconducting microwave resonator achieving a large hyperfine-mediated coupling between a resonator mode and the nuclear spin that could be used for the realization and readout of qudits.
