Weakly Driven and Finite Detuning Boundary Time Crystals Enabled by Low-Dissipation Dynamical Channels
Xiang Guo, Xiaojun Zhang, Zhihai Wang
Spontaneous breaking of continuous time-translation symmetry in driven-dissipative systems gives rise to boundary time crystals (BTCs), characterized by persistent oscillations sus…
Measurement-induced generation of Schrödinger cat states in cavity QED
Tong Wang, Peng-Fei Wei, Hai-Jun Xing +1
Schrödinger cat states, representing coherent superpositions of macroscopically distinguishable states, are indispensable nonclassical resources for continuous-variable quantum inf…
Bound state in the continuum and dynamics via phase modulation in giant-atom waveguide setups
Ji Qi, Xiaojun Zhang, Honngwei Yu +1
Giant atoms, which couple to a waveguide through multiple spatially separated connection points beyond the dipole approximation, provide a versatile route for quantum information p…
Bound state in the continuum and multiple atom state transfer applications in a waveguide QED setup
Xiang Guo, Xiaojun Zhang, Mingzhu Weng +5
Bound states in the continuum (BICs) have been extensively exploited to enhance light--matter interactions in metamaterials, yet their emergence and utility in multi-atom waveguide…
Quantum state preparation and transfer based on the bound state in the doublon continuum
Xiaojun Zhang, Xiang Guo, Yan Zhang +3
Bound states in the continuum (BICs) have attracted intense interest, yet their many-particle counterparts remain largely unexplored in waveguide quantum electrodynamics. We identi…
Enantiodetection in a cavity QED setup with finite chiral molecules
Xiang Guo, Xiaojun Zhang, Yong Li +1
We investigate enantiodetection for both a single cyclic three-level chiral molecule and finite ensembles of such molecules by monitoring the steady-state intracavity photon number…
