The tunnelling of cooper pairs across a Josephson junction (JJ) allow for thenonlinear inductance necessary to construct superconducting qubits, amplifiers,and various other quantum circuits. An alternative approach using hybridsuperconductor-semiconductor JJs can enable a superconducting qubitarchitecture with full electric field control. Here we present continuous-waveand time-domain characterization of gatemon qubits based on an InAs 2DEG. Weshow that the qubit undergoes a vacuum Rabi splitting with a readout cavity andwe drive coherent Rabi oscillations between the qubit ground and first excitedstates. We measure qubit coherence times to be $T_1 =$ 100 ns over a 1.5 GHztunable band. While various loss mechanisms are present in III-V gatemoncircuits we detail future directions in enhancing the coherence times of qubitdevices on this platform.
