Robustness of entanglement in a non-Hermitian cavity-optomechanical system even away from exceptional points
Jia-Jia Wang, Yu-Hong He, Chang-Geng Liao +2
Quantum physics can be extended into the complex domain by considering non-Hermitian Hamiltonians that are -symmetric. These exhibit exceptional points (EPs) where th…
Reservoir-engineered entanglement in a hybrid modulated three-mode optomechanical system
Chang-Geng Liao, Rong-Xin Chen, Hong Xie +1
We propose an effective approach for generating highly pure and strong cavity-mechanical entanglement (or optical-microwave entanglement) in a hybrid modulated three-mode optomecha…
Suppression of quantum noises in coherent atom lithography through squeezing
Anqi Zhang, Zeyang Liao, Rongxin Chen +1
The Abbe's diffraction limit restricts the resolution of an optical imaging and lithography system. Coherent Rabi oscillation is shown to be able to overcome the diffraction limit…
Electromagnetically induced transparency with controlled van der Waals interaction
Huaizhi Wu, Meng-Meng Bian, Li-Tuo Shen +3
We study the electromagnetically induced transparency (EIT) effect with two individually addressed four-level Rydberg atoms subjected to the interatomic van der Waals interaction.…
Quantum phase transition of polaritonic excitations in a multi-excitation coupled array
Li-Tuo Shen, Rong-Xin Chen, Huai-Zhi Wu +3
We analyze the quantum phase transition-like behavior in the lowest energy state of a two-site coupled atom-cavity system, where each cavity contains one atom but the total excitat…
Distributed manipulation of two-qubit entanglement with coupled continuous variables
Li-Tuo Shen, Rong-Xin Chen, Huai-Zhi Wu +1
We study the dynamics of two qubits separately sent through two coupled resonators, each initially containing a coherent state field. We present analytical arguments and numerical…
Adiabatic approximation for three qubits ultrastrongly coupled to a harmonic oscillator
Li-Tuo Shen, Rong-Xin Chen, Huai-Zhi Wu +1
We study the system involving mutual interaction between three qubits and an oscillator within the ultrastrong coupling regime. We apply adiabatic approximation approach to explore…
Ground state of the asymmetric Rabi model in the ultrastrong coupling regime
Li-Tuo Shen, Zhen-Biao Yang, Mei Lu +2
We study the ground states of the single- and two-qubit asymmetric Rabi models, in which the qubit-oscillator coupling strengths for the counterrotating-wave and corotating-wave in…
Ground state of three qubits coupled to a harmonic oscillator with ultrastrong coupling
Li-Tuo Shen, Zhen-Biao Yang, Rong-Xin Chen
We study the Rabi model composed of three qubits coupled to a harmonic oscillator without involving the rotating-wave approximation. We show that the ground state of the three-qubi…
