Open quantum systems are harder to track than open classical systems [PDF]
Quantum, 2019 For a Markovian (in the strongest sense) open quantum system it is possible, by continuously monitoring the environment, to perfectly track the system; that is, to know the stochastically evolving pure state of the system without altering the master ...

Multipartite quantum correlations in open quantum systems
New Journal of Physics, 2013 In this paper, we present a measure of quantum correlation for a multipartite system, defined as the sum of the correlations for all possible partitions.

Simulation of open quantum systems on universal quantum computers [PDF]
QuantumThe rapid development of quantum computers has enabled demonstrations of quantum advantages on various tasks. However, real quantum systems are always dissipative due to their inevitable interaction with the environment, and the resulting non-unitary ...

Quantum Zeno Effect in Open Quantum Systems [PDF]
Annales Henri Poincaré, 2021 AbstractWe prove the quantum Zeno effect in open quantum systems whose evolution, governed by quantum dynamical semigroups, is repeatedly and frequently interrupted by the action of a quantum operation. For the case of a quantum dynamical semigroup with a bounded generator, our analysis leads to a refinement of existing results and extends them to a ...

Complexity for an open quantum system [PDF]
Physical Review D, 2022 ندرس التعقيد لنظام كمومي مفتوح. نظامنا عبارة عن مذبذب توافقي مقترن بمجال رقمي أحادي البعد عديم الكتلة، والذي يعمل كحمام. على وجه التحديد، نأخذ في الاعتبار مصفوفة الكثافة المنخفضة من خلال تتبع درجات حرية الحمام لكل من المذبذبات العادية والمقلوبة وحساب تعقيد التنقية والتعقيد باستخدام تخطيط حالة المشغل.

International Journal of Modern Physics E, 1994 The damping of the harmonic oscillator is studied in the framework of the Lindblad theory for open quantum systems. A generalization of the fundamental constraints on quantum mechanical diffusion coefficients which appear in the master equation for the damped quantum oscillator is presented; the Schrödinger, Heisenberg and Weyl-Wigner-Moyal ...

From Open Quantum Systems to Open Quantum Maps [PDF]
Communications in Mathematical Physics, 2011 For a class of quantized open chaotic systems satisfying a natural dynamical assumption, we show that the study of the resolvent, and hence of scattering and resonances, can be reduced to the study of a family of open quantum maps, that is of finite dimensional operators obtained by quantizing the Poincaré map associated with the flow near the set of ...

Current in Open Quantum Systems [PDF]
Physical Review Letters, 2004 We show that a dissipative current component is present in the dynamics generated by a Liouville-master equation, in addition to the usual component associated with Hamiltonian evolution. The dissipative component originates from coarse graining in time, implicit in a master equation, and needs to be included to preserve current continuity.

Localization in Open Quantum Systems [PDF]
Physical Review Letters, 2017 In an isolated single-particle quantum system a spatial disorder can induce Anderson localization. Being a result of interference, this phenomenon is expected to be fragile in the face of dissipation. Here we show that dissipation can drive a disordered system into a steady state with tunable localization properties.
