Quantum Adiabatic Algorithm Design using Reinforcement Learning
Jian Lin, Zhong Yuan Lai, Xiaopeng Li
Quantum algorithm design plays a crucial role in exploiting the computational advantage of quantum devices. Here we develop a deep-reinforcement-learning based approach for quantum…
Quantum Rabi-Stark model: Solutions and exotic energy spectra
You-Fei Xie, Liwei Duan, Qing-Hu Chen
The quantum Rabi-Stark model, where the linear dipole coupling and the nonlinear Stark-like coupling are present on an equal footing, are studied within the Bogoliubov operators ap…
On-Chip Chiral Single-Photon Interface: Isolation and Unidirectional Emission
Lei Tang, Jiangshan Tang, Weidong Zhang +5
Chiral quantum systems have received intensive attention in fundamental physics and applications in quantum information processing including optical isolation and photon unidirecti…
Experimental test of contextuality in quantum and classical systems
Aonan Zhang, Huichao Xu, Jie Xie +4
Contextuality is considered as an intrinsic signature of non-classicality, and a crucial resource for achieving unique advantages of quantum information processing. However, recent…
Pseudo-magnetic field and effective spin-orbit interaction for a spin-1/2 particle confined to a curved surface
Guo-Hua Liang, Yong-Long Wang, Meng-Yun Lai +3
By considering the spin connection, we deduce the effective equation for a spin-1/2 particle confined to a curved surface with the non-relativistic limit and in the thin-layer quan…
Achieving Heisenberg-scaling precision with projective measurement on single photons
Geng Chen, Lijian Zhang, Wen-Hao Zhang +11
It has been suggested that both quantum superpositions and nonlinear interactions are important resources for quantum metrology. However, to date the different roles that these two…
The mixed quantum Rabi model
Liwei Duan, You-Fei Xie, Qing-Hu Chen
The analytical exact solutions to the mixed quantum Rabi model (QRM) including both one- and two-photon terms are found by using Bogoliubov operators. Transcendental functions in t…
Quantifying Operations with an Application to Coherence
Thomas Theurer, Dario Egloff, Lijian Zhang +1
To describe certain facets of non-classicality, it is necessary to quantify properties of operations instead of states. This is the case if one wants to quantify how well an operat…
Efficient Verification of Hypergraph States
Huangjun Zhu, Masahito Hayashi
Graph states and hypergraph states are of wide interest in quantum information processing and foundational studies. Efficient verification of these states is a key to various appli…
Generalized quantum Rabi model with both one- and two-photon terms: A concise analytical study
You-Fei Xie, Liwei Duan, Qing-Hu Chen
A generalized quantum Rabi Hamiltonian with both one- and two-photon terms has emerged in the circuit quantum electrodynamics system for a decade. The usual parity symmetry is brok…
Quantum Information Scrambling Through a High-Complexity Operator Mapping
Xiaopeng Li, Guanyu Zhu, Muxin Han +1
Quantum information scrambling has attracted much attention amid the effort to reconcile the conflict between quantum-mechanical unitarity and the thermalizaiton-irreversibility in…
Enhanced entanglement criterion via symmetric informationally complete measurements
Jiangwei Shang, Ali Asadian, Huangjun Zhu +1
We show that a special type of measurements, called symmetric informationally complete positive operator-valued measures (SIC POVMs), provide a stronger entanglement detection crit…
Observation of anomalous π modes in photonic Floquet engineering
Qingqing Cheng, Yiming Pan, Huaiqiang Wang +7
Recent progresses on Floquet topological phases have shed new light on time-dependant quantum systems, among which one-dimensional (1D) Floquet systems have been under extensive th…
Controlled quantum search on structured databases
Yunkai Wang, Shengjun Wu, Wei Wang
We present quantum algorithms to search for marked vertices in structured databases with low connectivity. Adopting a multi-stage search process, we achieve a success probability c…
Chaotic synchronization of two optical cavity modes in optomechanical systems
Nan Yang, Adam Miranowicz, Yong-Chun Liu +2
The synchronization of the motion of microresonators has attracted considerable attention. Here we present theoretical methods to synchronize the chaotic motion of two optical cavi…
