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.

Symmetry of Open Quantum Systems: Classification of Dissipative Quantum Chaos [PDF]
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 ...

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 .

Digital Quantum Simulation of Open Quantum Systems Using Quantum Imaginary–Time Evolution [PDF]
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 ...

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.
