Inversion of Qubit Energy Levels in Qubit-Oscillator Circuits in the Deep-Strong-Coupling Regime
Fumiki Yoshihara, Tomoko Fuse, Ziqiao Ao +6
We report on experimentally measured light shifts of superconducting flux qubits deep-strongly coupled to LC oscillators, where the coupling constants are comparable to the qubit a…

Quantum non-demolition detection of an itinerant microwave photon
S. Kono, K. Koshino, Y. Tabuchi +2
Photon detectors are an elementary tool to measure electromagnetic waves at the quantum limit and are heavily demanded in the emerging quantum technologies such as communication, s…

Nonclassical photon number distribution in a superconducting cavity under a squeezed drive
S. Kono, Y. Masuyama, T. Ishikawa +5
A superconducting qubit in the strong dispersive regime of a circuit quantum electrodynamics system is a powerful probe for microwave photons in a cavity mode. In this regime, a qu…
