Transmon qubit in a magnetic field: Evolution of coherence and transition frequency

We report on spectroscopic and time-domain measurements on a fixed-frequency concentric transmon qubit in an applied in-plane magnetic field to explore its limits of magnetic field compatibility. We demonstrate quantum coherence of the qubit up to field values of B=40mT, even without an optimized ch...
