Chiral Quantum Entanglement Transfer with Giant Atoms
Peng-Fei Wang, Lei Huang, Yi-Long-Yue Guo +4
We investigate entanglement transfer in a multi-giant-atom waveguide system. By tailoring chiral spontaneous emission and exploiting dark-state dynamics, the setup enables perfect,…
Controlling entanglement by phase engineering in giant-atom waveguide
Peng-Fei Wang, Lei Huang, Miao-Miao Wei +2
We investigate the entanglement dynamics of two giant atoms coupled to a common waveguide. By introducing additional phase modulation at each coupling point, every photon propagati…
Unidirectional reflection lasing based on destructive interference and Bragg scattering modulation in defective atomic lattice
Xinfu Zheng, Chen Peng, Duanfu Chen +5
The novel and ingenious scheme we propose for achieving unidirectional reflection lasing (URL) involves integrating a one-dimensional (1D) defective atomic lattice with a coherent…
Unidirectional spectral singularity lasing in a defective atomic lattice
Chen Peng, Xinfu Zheng, Duanfu Chen +4
We propose an efficient scheme for achieving mode-tunable unidirectional reflection lasing (URL) by establishing a coherent gain atomic system to amplify the probe field and ingeni…
Unidirectional lasing via vacuum induced coherent in defective atomic lattice
Xinfu Zheng, Chen Peng, Duanfu Chen +5
We skillfully utilized vacuum induced coherence to amplify the probe light, and then successfully achieved both nonreciprocal reflection and lasing oscillation in a single physical…
