Quantum Simulation of Two-Dimensional Gauge Theory in Rydberg and Rydberg-Dressed Atom Arrays
Zheng Zhou, Zheng Yan, Changle Liu +2
Simulating quantum gauge theories with spatial dimension greater than one is of great physical significance yet has not been achieved experimentally. Here we propos…
Enhancing dissipative cat-state generation via nonequilibrium pump fields
Zheng-Yang Zhou, Clemens Gneiting, Wei Qin +2
Cat states, which were initially proposed to manifest macroscopic superpositions, play an outstanding role in fundamental aspects of quantum dynamics. In addition, they have potent…
Generating and detecting entangled cat states in dissipatively coupled degenerate optical parametric oscillators
Zheng-Yang Zhou, Clemens Gneiting, J. Q. You +1
Non-Gaussian continuous variable states play a central role both in the foundations of quantum theory and for emergent quantum technologies. In particular, "cat states", i.e., two-…
Accessing the bath information in open quantum systems with the stochastic c-number Langevin equation method
Zheng-Yang Zhou, Yun-An Yan, Stephen Hughes +2
In traditional open quantum systems, the baths are usually traced out so that only the system information is left in the equations of motion. However, recent studies reveal that us…
Protection of Logical Qubits via Optimal State Transfers
Jiang Zhang, Zheng-Yang Zhou, Lian-Ao Wu +1
Dynamical decoupling can enforce a symmetry on the dynamics of an open quantum system. Here we develop an efficient dynamical-decoupling-based strategy to create the decoherence-fr…
Dark state with counter-rotating dissipative channels
Zheng-yang Zhou, Mi Chen, Lian-Ao Wu +2
Dark state as a consequence of interference between different quantum states has great importance in the fields of chip-scale atomic clock and quantum information. For the -type…
Quantum Langevin approach for non-Markovian quantum dynamics of the spin-boson model
Zheng-Yang Zhou, Mi Chen, Ting Yu +1
One long-standing difficult problem in quantum dissipative dynamics is to solve the spin-boson model in a non-Markovian regime where a tractable systematic master equation does not…
Second order tunneling of two interacting bosons in a driven triple well
Zheng Zhou, Wenhua Hai, Qiongtao Xie +1
We investigate quantum tunneling of two repulsive bosons in a triple-well potential subject to a high-frequency driving field. By means of the multiple-time-scale asymptotic analys…
Coherent control via interplay between driving field and two-body interaction in a double well
Juan Liu, Wenhua Hai, Zheng Zhou
We investigate interplay between external field and interatomic interaction and its applications to coherent control of quantum tunneling for two repulsive bosons confined in a hig…
