It has been predicted that longitudinal coupling between a qubit and a superconducting resonator can mediate efficient interactions among distant qubits. Here the authors implement such a coupling between a singlet-triplet qubit in a semiconductor double quantum dot and a high-impedance superconducting resonator.
