Effective temperature pulses in open quantum systems
Physical Review Research, 2022 Controlling the temperature of nanoscale quantum systems is becoming increasingly important in the efforts to develop thermal devices such as quantum heat valves, heat engines, and refrigerators and to explore fundamental concepts in quantum ...

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 ...

Krylov complexity in open quantum systems [PDF]
Physical Review Research, 2023 Krylov complexity is a measure of operator complexity that exhibits universal behavior and bounds a large class of other measures. In this paper, we generalize Krylov complexity from a closed system to an open system coupled to a Markovian bath, where ...

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.

Round table on open quantum systems [PDF]
EPJ Web of Conferences, 2022 This is a discussion about open quantum systems and its application to the study of hard probes. It reviews some of the things that were said in the corresponding round table. Views are only my own.

Symmetry Protected Topological Order in Open Quantum Systems [PDF]
Quantum, 2021 We systematically investigate the robustness of symmetry protected topological (SPT) order in open quantum systems by studying the evolution of string order parameters and other probes under noisy channels.

Hilbert space fragmentation in open quantum systems [PDF]
Physical Review Research, 2023 We investigate the phenomenon of Hilbert space fragmentation (HSF) in open quantum systems and find that it can stabilize highly entangled steady states.

Sublinear Scaling in Non-Markovian Open Quantum Systems Simulations [PDF]
Physical Review X, 2023 While several numerical techniques are available for predicting the dynamics of non-Markovian open quantum systems, most struggle with simulations for very long memory and propagation times, e.g., due to superlinear scaling with the number of time steps $
