Spinning giant optomechanical cavity with nonreciprocal self-interference
Yao-Tong Chen
We study a spinning optomechanical cavity that is coupled to a meandering waveguide at multiple spatially separated points, forming a giant-cavity configuration. The resulting self…
Single-photon manipulations based on optically-controlled chiral couplings in waveguide structures of Rydberg giant atoms
Yao-Tong Chen, Lei Du, Zhihai Wang +3
Two interacting Rydberg atoms coupled to a waveguide realize a giant-atom platform that exhibits the controllable (phase-dependent) chirality where the direction of nonreciprocal p…
Giant-Atom Effects on Population and Entanglement Dynamics of Rydberg Atoms
Yao-Tong Chen, Lei Du, Yan Zhang +4
Giant atoms are attracting interest as an emerging paradigm in the quantum optics of engineered waveguides. Here we propose to realize a synthetic giant atom working in the optical…
Decay dynamics of a giant atom in a structured bath with broken time-reversal symmetry
Lei Du, Yao-Tong Chen, Yan Zhang +2
We study in this paper the decay dynamics of a two-level giant atom, which is coupled to a quasi-one-dimensional sawtooth lattice exposed to uniform synthetic magnetic fluxes. In t…
Nonreciprocal and chiral single-photon scattering for giant atoms
Yao-Tong Chen, Lei Du, Lingzhen Guo +4
Quantum optics with giant atoms has provided a new paradigm to study photon scatterings. In this work, we investigate the nontrivial single-photon scattering properties of giant at…
Giant atoms with time-dependent couplings
Lei Du, Yao-Tong Chen, Yan Zhang +1
We study the decay dynamics of a two-level giant atom that is coupled to a waveguide with time-dependent coupling strengths. In the non-Markovian regime where the retardation effec…
Nonreciprocal frequency conversion with chiral -type atoms
Lei Du, Yao-Tong Chen, Yong Li
In this paper, we begin with a model of a -type atom whose both transitions are chirally coupled to a waveguide and then extend the model to its giant-atom version. We investiga…
Perfect Transfer of enhanced entanglement and asymmetric steering in a cavity magnomechanical system
Yao-Tong Chen, Lei Du, Yan Zhang +1
We propose a hybrid cavity magnomechanical system to realize and transfer the bipartite entanglements and Einstein-Podolsky-Rosen (EPR) steerings between magnons, photons, and phon…
Nonreciprocal quantum interference and coherent photon routing in a three-port optomechanical system
Lei Du, Yao-Tong Chen, Jin-Hui Wu +1
We study the quantum interference between different weak signals in a three-port optomechanical system, which is achieved by coupling three cavity modes to the same mechanical mode…
Universal quantum computing with superconducting charge qubits
Nian-Quan Jiang, Yao Chen, Chuanbing Cai +2
Superconducting quantum circuit is a promising system for building quantum computer. With this system we demonstrate the universal quantum computations, including the preparing of…
