Speeding up quantum dissipative dynamics of open systems with kernel methods [PDF]
, 2021 The future forecasting ability of machine learning (ML) makes ML a promising tool for predicting long-time quantum dissipative dynamics of open systems. In this article, we employ nonparametric ML algorithm (kernel ridge regression as a representative of

Quantum Dissipative Systems and Feedback Control Design by Interconnection [PDF]
IEEE Transactions on Automatic Control, 2007 The purpose of this paper is to extend J.C. Willems' theory of dissipative systems to open quantum systems described by quantum noise models. This theory, which combines ideas from quantum physics and control theory, provides useful methods for analysis ...

Dissipative phase transitions in n-photon driven quantum nonlinear resonators [PDF]
Quantum, 2023 We investigate and characterize the emergence of finite-component dissipative phase transitions (DPTs) in nonlinear photon resonators subject to n-photon driving and dissipation.

Dissipative quantum metrology in manybody systems of identical particles [PDF]
New Journal of Physics, 2014 Estimation of physical parameters is essential in almost any part of science and technology. The enhancement of performance in this task (e.g. beating the standard classical shot-noise limit) using available physical resources is a major goal in ...

Dissipative quantum chaos unveiled by stochastic quantum trajectories [PDF]
Physical Review ResearchWe define quantum chaos and integrability in open quantum many-body systems as a dynamical property of single stochastic realizations, referred to as quantum trajectories.

Dissipative Properties of Quantum Systems [PDF]
Proceedings of the National Academy of Sciences, 1972 We consider the dissipative properties of large quantum systems from the point of view of kinetic theory. The existence of a nontrivial collision operator imposes restrictions on the possible collisional invariants of the system. We consider a model in which a discrete level is coupled to a set of quantum states and which, in the limit of a large ...

From Geometry to Coherent Dissipative Dynamics in Quantum Mechanics
Quantum Reports, 2021 Starting from the geometric description of quantum systems, we propose a novel approach to time-independent dissipative quantum processes according to which energy is dissipated but the coherence of the states is preserved.

Quantum Zeno and anti-Zeno effects in quantum dissipative systems [PDF]
, 2017 We investigate the quantum Zeno and anti-Zeno effects in quantum dissipative systems by employing a hierarchical equations of motion approach which is beyond the usual Markovian approximation, the rotating wave approximation, and the perturbative ...

Statistical correlations in the oscillator model of quantum dissipative systems [PDF]
, 2018 SummaryWe study the problem of the initial conditions for the oscillator model of quantum dissipative systems. It is argued that, even in the classical case, the hypothesis that the environment is in thermal equilibrium implies a statistical correlation ...

Quantum Nonreciprocal Interactions via Dissipative Gauge Symmetry
PRX Quantum, 2023 One-way nonreciprocal interactions between two quantum systems are typically described by a cascaded quantum master equation, and rely on an effective breaking of time-reversal symmetry (TRS) as well as the balancing of coherent and dissipative ...
