Exact dynamics of first-order system-bath coherence in bilinear bosonic models
Yang-Yang Xie, Song-Lin Wu, Paul Brumer +2
We investigate the exact dynamics of first-order system--bath coherence induced by excitation exchange in bilinear bosonic models. By solving the linear Heisenberg equations, we ob…
Symmetry and Exact Solutions of General Spin-Boson Models
Yifan Sun, Lian-Ao Wu
Spin-boson models are the canonical benchmark for quantum dissipation. We show the symmetry structure of general spin-boson Hamiltonians and obtain their spectra explicitly by expl…
Detecting Initial System-Environment Correlations from a Single Observable
Ali Abu-Nada, Russell Ceballos, Lian-Ao Wu
We address the problem of detecting initial system--environment correlations when the environment is not directly accessible. Most existing approaches rely on full state tomography…
Machine-Learning-Assisted Pulse Design for State Preparation in a Noisy Environment
Zhao-Wei Wang, Hong-Yang Ma, Yun-An Yan +2
High-precision quantum control is essential for quantum computing and quantum information processing. However, its practical implementation is challenged by environmental noise, wh…
Enhanced Algorithmic Perfect State Transfer on IBM Quantum Computers
Zong-Yuan Ge, Lian-Ao Wu, Zhao-Ming Wang
Perfect state transfer (PST) through a spin chain can be theoretically obtained via predesigned PST couplings. However, the corresponding experiment on IBM quantum computers demons…
Noise-resilient Universal Quantum Computing in the Presence of Anisotropic Noise
Yang-Yang Xie, Zhao-Ming Wang, Lian-Ao Wu
We propose a universal gate set for quantum computing that operates in the presence of decoherence without the overhead of active error correction. We show that a broad class of an…
Steady-State Coherences under Partial Collective non-Markovian Decoherence
S. L. Wu, W. Ma, Zhao-Ming Wang +2
Steady-state coherence in open quantum systems is crucial for quantum technologies, yet its behavior is not fully understood due to the interplay between collective and individual…
Going beyond quantum Markovianity and back to reality: An exact master equation study
Zhao-Ming Wang, S. L. Wu, Mark S. Byrd +1
The precise characterization of dynamics in open quantum systems often presents significant challenges, leading to the introduction of various approximations to simplify a model. O…
Non-Markovian environment induced anomaly in steady state quantum coherence
Arapat Ablimit, Zhao-Ming Wang, Feng-Hua Ren +2
Environment induced steady state quantum coherence (SSQC) is a captivating phenomenon that challenges conventional understandings of decoherence. In this letter, we delve into the…
