Thermal noise cancellation for optomechanically induced nonreciprocity in a whispering-gallery-mode microresonator
Zhi-Xiang Tang, Xun-Wei Xu
Magnetic-free optomechanically induced nonreciprocity may stimulate a wide range of practical applications in quantum technologies. However, how to suppress the thermal noise flow…
Multiterminal Nonreciprocal Routing in an Optomechanical Plaquette via Synthetic Magnetism
Zhi-Xiang Tang, Xun-Wei Xu
Optomechanical systems with parametric coupling between optical (photon) and mechanical (phonon) modes provide a useful platform to realize various magnetic-free nonreciprocal devi…
Control the qubit-qubit coupling in the superconducting circuit with double-resonator couplers
Hui Wang, Yan-Jun Zhao, Hui-Chen Sun +5
We propose a scheme of using two fixed frequency resonator couplers to tune the coupling strength between two Xmon qubits. The induced indirect qubit-qubit interactions by two reso…
Switching classical and quantum nonreciprocities with spinning photonics
Yonglin Xiang, Yunlan Zuo, Xun-Wei Xu +2
We study how to achieve, manipulate, and switch classical or quantum nonreciprocal effects of light with a spinning Kerr resonator. In particular, we show that even when there is n…
Loss-Induced Quantum Revival
Yunlan Zuo, Ran Huang, Le-Man Kuang +2
Conventional wisdom holds that quantum effects are fragile and can be destroyed by loss. Here, contrary to general belief, we show how to realize quantum revival of optical correla…
General corner states in 2D SSH model with intracelluar next-nearest-neighbour hopping
Xun-Wei Xu, Yu-Zeng Li, Zheng-Fang Liu +1
We investigate corner states in a photonic two-dimensional (2D) Su-Schrieffer-Heeger (SSH) model on a square lattice with zero gauge flux. By considering intracelluar next-nearest-…
