Hamiltonian open quantum system toolkit [PDF]
Communications Physics, 2022 In quantum computing, simulating continuously evolving open quantum systems is key to describe dynamical processes on noisy quantum devices. Here, the authors present an open-source software package “Hamiltonian Open Quantum System Toolkit” (HOQST) for ...

Quantum Information Scrambling in Non-Markovian Open Quantum System [PDF]
Entropy, 2022 In this paper, we investigate the dynamics of a spin chain whose two end spins interact with two independent non-Markovian baths by using the non-Markovian quantum state diffusion (QSD) equation approach.

Work Measurement in OPEN Quantum System [PDF]
Entropy, 2022 Work is an important quantity in thermodynamics. In a closed quanutm system, the two-point energy measurements can be applied to measure the work but cannot be utilized in an open quantum system.

Singly-excited resonant open quantum system Tavis-Cummings model with quantum circuit mapping [PDF]
Scientific Reports, 2023 Tavis-Cummings (TC) cavity quantum electrodynamical effects, describing the interaction of N atoms with an optical resonator, are at the core of atomic, optical and solid state physics.

Two-Unitary Decomposition Algorithm and Open Quantum System Simulation [PDF]
Quantum, 2023 Simulating general quantum processes that describe realistic interactions of quantum systems following a non-unitary evolution is challenging for conventional quantum computers that directly implement unitary gates.

Accessible coherence in open quantum system dynamics [PDF]
Quantum, 2020 Quantum coherence generated in a physical process can only be cast as a potentially useful resource if its effects can be detected at a later time. Recently, the notion of non-coherence-generating-and-detecting (NCGD) dynamics has been introduced and ...

Experimental test of exchange fluctuation relations in an open quantum system [PDF]
Physical Review Research, 2020 Elucidating the energy transfer between a quantum system and a reservoir is a central issue in quantum nonequilibrium thermodynamics, which could provide novel tools to engineer quantum-enhanced heat engines.

A cosmological open quantum system
Physical Review D, 2018 We derive the evolution equation for the density matrix of a UV- and IR- limited band of comoving momentum modes of the canonically normalized scalar degree of freedom in two examples of nearly de Sitter universes.
