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 ...

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 ...

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.

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 ...

Time crystallinity in open quantum systems [PDF]
Quantum, 2020 Time crystals are genuinely non-equilibrium quantum phases of matter that break time-translational symmetry. While in non-equilibrium closed systems time crystals have been experimentally realized, it remains an open question whether or not such a phase ...
