A Unified Error Correction Code for Universal Quantum Computing with Identical Particles
S. L. Wu, Lian-Ao Wu
We present a universal fault-tolerant quantum computing architecture based on identical particle qubits (IPQs), where we find that the first-order IPQ - bath interaction fundamenta…
The driven-Markovian master equation based on the Lewis-Riesenfeld invariants theory
S. L. Wu, X. L. Huang, X. X. Yi
We derive a Markovian master equation for driven open quantum systems based on the Lewis-Riesenfeld invariants theory, which is available for arbitrary driving protocols.The role o…
Dynamics of a driven open double two-level system and its entanglement generation
W. Ma, X. L. Huang, S. L. Wu
We investigate the dynamics of the driven open double two-level system by deriving a driven Markovian master equation based on the Lewis-Riesenfeld invariant theory. The transition…
Effect of quantum jumps on non-Hermitian system
Xiangyu Niu, Jianning Li, S. L. Wu +1
One among the possible realizations of non-Hermitian systems is based on open quantum systems by omitting quantum jumping terms in the master equation. This is a good approximation…
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…
Multilevel quantum Otto heat engines with identical particles
X. L. Huang, D. Y. Guo, S. L. Wu +1
A quantum Otto heat engine is studied with multilevel identical particles trapped in one-dimensional box potential as working substance. The symmetrical wave function for Bosons an…
Shortcuts to adiabaticity in non-Hermitian quantum systems without rotating-wave approximation
Hong Li, H. Z. Shen, S. L. Wu +1
The technique of shortcuts to adiabaticity (STA) has attracted broad attention due to their possible applications in quantum information processing and quantum control. However, mo…
Adiabatic Decoherence-Free Subspaces and its Shortcuts
S. L. Wu, X. L. Huang, H. Li +1
The adiabatic theorem and "shortcuts to adiabaticity" for the adiabatic dynamics of time-dependent decoherence-free subspaces are explored in this paper. Starting from the definiti…
The Dynamical Invariant of Open Quantum System
S. L. Wu, X. Y. Zhang, X. X. Yi
The dynamical invariant, whose expectation value is constant, is generalized to open quantum system. The evolution equation of dynamical invariant (the dynamical invariant conditio…
Time-dependent Decoherence-Free Subspace
S. L. Wu, L. C. Wang, X. X. Yi
With time-dependent Lindblad operators, an open system may have a time-dependent decoherence-free subspace (t-DFS). In this paper, we define the t-DFS and present a necessary and s…
Berry Phase and Hannay's Angle in a Quantum-Classical Hybrid System
H. D. Liu, S. L. Wu, X. X. Yi
Berry phase, which had been discovered for more than two decades, provides us a very deep insight on the geometric structure of quantum mechanics. Its classical counterpart--Hannay…
Experimentally realizable control fields in quantum Lyapunov control
X. X. Yi, S. L. Wu, Chunfeng Wu +2
As a hybrid of techniques from open-loop and feedback control, Lyapunov control has the advantage that it is free from the measurement-induced decoherence but it includes the syste…
Information Flow, Non-Markovianity and Geometric Phases
S. L. Wu, X. L. Huang, L. C. Wang +1
Geometric phases and information flows of a two-level system coupled to its environment are calculated and analyzed. The information flow is defined as a cumulant of changes in tra…
Born-Oppenheimer approximation for open quantum systems within the quantum trajectory approach
X. L. Huang, S. L. Wu, L. C. Wang +1
Based on the quantum trajectory approach, we extend the Born-Oppenheimer (BO) approximation from closed quantum system to open quantum system, where the open quantum system is desc…
