Active quantum memory: Exploring the quantum dynamical process of voltage-gated ion channel
Yu-Juan Sun, Wei-Min Zhang
It is known that the opening or closing mechanism of a voltage-gated ion channel is triggered by the potential difference across the cell membrane in the nervous system. Based on t…
Two-mode Open Quantum Systems: Decoherence and Localized Bound State Dynamics
Chia-Yi Lin, Chuan-Zhe Yao, Hon-Lam Lai +2
Dissipationless localized bound states of open quantum systems are significantly robust to decoherence and have potential applications in quantum technologies. In this work, the de…
The strong-coupling quantum thermodynamics of quantum Brownian motion based on the exact solution of its reduced density matrix
Chuan-Zhe Yao, Wei-Min Zhang
We derive the quantum thermodynamics of quantum Brownian motion from the exact solution of its reduced density matrix. We start from the total equilibrium thermal state between the…
Unveiling the Dynamical Genesis of Quantum Entanglement in Linear Systems: Internal causality breaking in the reduced subsystem evolution
Shuang-Kai Yang, Wei-Min Zhang
Utilizing the general theory of open quantum systems to investigate the exact dynamical evolution of simple bilinear systems, we discover a mechanism of the dynamical genesis of qu…
