Quantum interference and controllable magic cavity QED via a giant atom in coupled resonator waveguide
Xiaojun Zhang, Chengge Liu, Zhirui Gong +1
We study the Markovian and Non-Markovian dynamics in a giant atom system which couples to a coupled resonator waveguide (CRW) via two distant sites. Under certain conditions, we fi…
Quantum sensing of rotation velocity based on Bose-Hubbard model
Che Jiang, Yaojie Zeng, Qi Qin +2
This work theoretically study the Bose-Hubbard model in a ring geometry in a rotating frame. We obtain an effective Hamiltonian by using unitary transformation, where the effect of…
Superconducting giant atom waveguide QED: Quantum Zeno and Anti-Zeno effects in ultrastrong coupling regime
Xiaojun Zhang, Weijun Cheng, Zhirui Gong +2
The giant atom system is a new paradigm in quantum optics, in which the traditional dipole approximation is not available. In this paper, we construct an artificial giant atom mode…
Ramsey Interferometry based on stimulated Brillouin scattering
Xian-Fu Quan, Zhi-Rui Gong, Shuo Zhang +3
Realizing highly sensitive interferometry is essential to accurate observation of quantum properties. Here we study two kinds of Ramsey interference fringes in a whispering-gallery…
symmetric phase transition and single-photon transmission in an optical trimmer system
L. F. Xue, Z. R. Gong, H. B. Zhu +1
The parity-time () symmetric structures have exhibited potential applications in developing various robust quantum devices. In an optical trimmer with balanced loss a…
Spontaneous Decoherence of Coupled Harmonic Oscillators Confined in A Ring
Z. R. Gong, Z. W. Zhang, D. Z. Xu +2
We study the spontaneous decoherence of the coupled harmonic oscillators confined in a ring container, where the nearest-neighbor harmonic potentials are taken into consideration.…
