• Authors: Ke-Xiong Yan, Yuan Qiu, Yang Xiao, Ye-Hong Chen, Yan Xia,
• Abstract summary: In quantum Rabi model, a three-photon resonance occurs when the cavity field bare frequency is about 1/3 of the atomic transition frequency. We show that the resonance can also be generated in the absence of the 1/3 condition by employing an artificial atom with tunable transition frequency. We derive an effective Hamiltonian to determine the magnitude of the energy splitting and the resonance position.

• Abstract: It is well known that in the quantum Rabi model, a three-photon resonance occurs when the cavity field bare frequency is about 1/3 of the atomic transition frequency. In this manuscript, we show that the resonance can also be generated in the absence of the 1/3 condition by employing an artificial atom with tunable transition frequency. To realize the protocol, the modulation frequency should be comparable to the cavity frequency in order to induce a counter-rotating interaction in the effective Hamiltonian. In this way, three-photon Rabi oscillations can be observed in a small-detuning regime, thus avoiding the excitation of high-energy states. We derive an effective Hamiltonian (equivalent to the anisotropic Rabi model Hamiltonian) to determine the magnitude of the energy splitting and the resonance position. Numerical simulations results show that the protocol not only generates a three-photon resonance, but also has a detectable output photon flux. We hope the protocol can be exploited for the realization of Fock-state sources and the generation of multiparticle entanglement.

  An angular-momentum-like basis is defined for quantum-entangled, two-photon states that form an angular-momentum-like basis. This basis provides a convenient starting point to study error-inducing effects of transmon anharmonicity, surrounding-environment decoherence, and random stray fields on qubit state and gate operations. The generality of the Schwinger angular-momentum construct allows it to be applied to other superconducting charge qubits.
