Synthesizing Arbitrary Non-Hermitian Hamiltonian with Stochastic Floquet Engineering
Lingzhen Guo, Hui Jing
The conventional Floquet engineering scheme synthesizes a given target Hamiltonian with a deterministic temporal periodic driving field. In this work, we introduce the stochastic F…
Selective high-order topological states and tunable chiral emission in atomic metasurfaces
Yi-Xin Wang, Yan Zhang, Lei Du +2
Atomic metasurfaces (AMs) provide a powerful nanophotonic platform for integrating topological effects into quantum many-body systems. In this Letter, we investigate the quantum op…
Chirality, Nonreciprocity and Symmetries for a Giant Atom
Luting Xu, Lingzhen Guo
Chiral and nonreciprocal quantum devices are crucial for signal routing and processing in a quantum network. In this work, we study the chirality and nonreciprocity of a giant atom…
Quantum dissipative dynamics of driven Duffing oscillator near attractors
Wei Feng, Lingzhen Guo
We investigate the quantum dissipative dynamics near the stable states (attractors) of a driven Duffing oscillator. A refined perturbation theory that can treat two perturbative pa…
Engineering Bosonic Codes with Quantum Lattice Gates
Lingzhen Guo, Tangyou Huang, Lei Du
Bosonic codes offer a hardware-efficient approach to encoding and protecting quantum information with a single continuous-variable bosonic system. In this paper, we introduce a new…
Perturbative Framework for Engineering Arbitrary Floquet Hamiltonian
Yingdan Xu, Lingzhen Guo
We develop a systematic perturbative framework to engineer an arbitrary target Hamiltonian in the Floquet phase space of a periodically driven oscillator based on Floquet-Magnus ex…
Catch and release of propagating bosonic field with non-Markovian giant atom
Luting Xu, Lingzhen Guo
The non-Markovianity of physical systems is considered to be a valuable resource that has potential applications to quantum information processing. The control of traveling quantum…
