Engineering the phase-robust topological router in a chiral-symmetric dimerized superconducting circuit lattice with long-range hopping
Li-Na Zheng, Hong-Fu Wang, Xuexi Yi
We propose a scheme to implement the phase-robust topological router based on a one-dimensional dimerized superconducting circuit lattice with long-range hopping. We show that the…
Quantum imaging exploiting twisted photon pairs
Dianzhen Cui, X. X. Yi, Li-Ping Yang
Quantum correlation of two-photon states has been utilized to suppress the environmental noise in imaging down to the single-photon level. However, the size of the coherence area o…
Dynamical localization in non-Hermitian quasi-crystals
C. M. Dai, Yunbo Zhang, Xuexi Yi
We study the localization transition in periodically driven one-dimensional non-Hermitian lattices where the piece-wise two-step drive is constituted by uniform coherent tunneling…
Quantum indirect synchronization
Guo Meitong, Niu Xiangyu, Yi Xuexi +1
It is well known that a system with two or more levels exists a limit cycle and can be synchronized with an external drive when the system and the drive are directly coupled. One m…
Detecting the effects of quantum gravity with exceptional points in optomechanical sensors
Dianzhen Cui, T. Li, Jianning Li +1
In this manuscript, working with a binary mechanical system, we examine the effect of quantum gravity on the exceptional points of the system. On the one side, we find that the exc…
Implementation of hybridly protected quantum gates
Chunfeng Wu, Chunfang Sun, Gangcheng Wang +2
We explore the implementation of hybridly protected quantum operations combining the merits of holonomy, dynamical decoupling approach and dephasing-free feature based on a simple…
Cramér-Rao bound and quantum parameter estimation with non-Hermitian systems
Jianning Li, Haodi Liu, Zhihai Wang +1
The quantum Fisher information constrains the achievable precision in parameter estimation via the quantum Cramér-Rao bound, which has attracted much attention in Hermitian systems…
Shortcuts to adiabaticity for open quantum systems and a mixed-state inverse engineering scheme
S. L. Wu, W. Ma, X. L. Huang +1
We propose a fast mixed-state control scheme to transfer the quantum state along designable trajectories in Hilbert space, which is robust to multiple decoherence noises. Starting…
Dynamics Reflect Gapless Edge Modes for Topological Superconductor
X. L. Zhao, M. Li, T. H. Qiu +4
We focus on the dynamical feature for a -wave superconductor model in different parameter regions in terms of the appearance of gapless edge modes in reel geometry. Firstly, we…
Discrete time-crystalline order in Bose-Hubbard model with dissipation
C. M. Dai, Z. C. Gu, X. X. Yi
Periodically driven quantum systems manifest various non-equilibrium features which are absent at equilibrium. For example, discrete time-translation symmetry can be broken in peri…
Indirect quantum control for finite-dimensional coupled systems
J. Nie, H. C. Fu, X. X. Yi
We present a new analysis on the quantum control for a quantum system coupled to a quantum probe. This analysis is based on the coherent control for the quantum system and a hypert…
