摘要
In this experiment, we couple a superconducting transmon qubit to a high-impedance 645 Omega microwave resonator. Doing so leads to a large qubit-resonator coupling rate g, measured through a large vacuum Rabi splitting of 2g similar or equal to 910 MHz. The coupling is a significant fraction of the qubit and resonator oscillation frequencies., placing our system close to the ultrastrong coupling regime ((g) over bar = g/omega = 0.071 on resonance). Combining this setup with a vacuum-gap transmon architecture shows the potential of reaching deep into the ultrastrong coupling (g) over bar similar to 0.45 with transmon qubits.
