General phase diagram features of superradiant phase transitions
Wen Zhao, Junlong Tian, Jie Peng
Various light-matter interactions lead to diverse phase diagram structures in superradiant phase transition (SPT) studies. Such systems consist of multiqubit and multimode with ani…

Dissipation-assisted few-photon optical diode
Teng-Fei Xiao, Junlong Tian, Jie Peng
We studied the coherent transport of one or two photons in a one-dimensional waveguide chirally coupled to a dissipative nonlinear cavity. The scattering amplitudes were derived an…

Deterministic two-photon C-Z gate with the two-photon quantum Rabi model
Jia-Cheng Tang, Jin Zhao, Haitao Yang +5
We propose a scheme for realizing a deterministic two-photon C-Z gate based on variants of the two-photon quantum Rabi model (QRM), which is feasible within the framework of circui…
