Assisted quantum simulation of open quantum systems
iScience, 2023 Summary: Universal quantum algorithms (UQA) implemented on fault-tolerant quantum computers are expected to achieve an exponential speedup over classical counterparts. However, the deep quantum circuits make the UQA implausible in the current era.

Stabilizer codes for open quantum systems
Scientific Reports, 2023 The Lindblad master equation describes the evolution of a large variety of open quantum systems. An important property of some open quantum systems is the existence of decoherence-free subspaces.

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.

Equilibrium States in Open Quantum Systems
Entropy, 2018 The aim of this paper is to study the question of whether or not equilibrium states exist in open quantum systems that are embedded in at least two environments and are described by a non-Hermitian Hamilton operator H .

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 ...

Quantum thermo-dynamical construction for driven open quantum systems [PDF]
Quantum, 2021 Quantum dynamics of driven open systems should be compatible with both quantum mechanic and thermodynamic principles. By formulating the thermodynamic principles in terms of a set of postulates we obtain a thermodynamically consistent master equation ...

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 ...

Dissipation-Induced Information Scrambling in a Collision Model
Entropy, 2022 In this paper, we present a collision model to stroboscopically simulate the dynamics of information in dissipative systems. In particular, an all-optical scheme is proposed to investigate the information scrambling of bosonic systems with Gaussian ...

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 ...
