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…
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…
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…
