Assisted quantum simulation of open quantum systems [PDF]
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 [PDF]
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.

Equilibrium States in Open Quantum Systems [PDF]
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 .

Symmetry of Open Quantum Systems: Classification of Dissipative Quantum Chaos
PRX Quantum, 2023 We develop a theory of symmetry in open quantum systems. Using the operator-state mapping, we characterize symmetry of Liouvillian superoperators for the open quantum dynamics by symmetry of operators in the double Hilbert space and apply the 38-fold ...

Digital Quantum Simulation of Open Quantum Systems Using Quantum Imaginary–Time Evolution
PRX Quantum, 2022 Quantum simulation on emerging quantum hardware is a topic of intense interest. While many studies focus on computing ground-state properties or simulating unitary dynamics of closed systems, open quantum systems are an interesting target of study owing ...

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.

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.
