Singlet-Doublet Transitions of a Quantum Dot Josephson Junction Detected in a Transmon Circuit
We realize a hybrid superconductor-semiconductor transmon device in which the Josephson effect is controlled by a gate-defined quantum dot in an InAs-Al nanowire. Microwave spectroscopy of the transition spectrum of the transmon allows us to probe the ground-state parity of the quantum dot as a func...
