A Note on the Relativistic Transformation Properties of Quantum Stochastic Calculus
EntropyWe present a simple argument to derive the transformation of the quantum stochastic calculus formalism between inertial observers and derive the quantum open system dynamics for a system moving in a vacuum (or, more generally, a coherent) quantum field ...

A quantum algorithm for evolving open quantum dynamics on quantum computing devices
Scientific Reports, 2020 Designing quantum algorithms for simulating quantum systems has seen enormous progress, yet few studies have been done to develop quantum algorithms for open quantum dynamics despite its importance in modeling the system-environment interaction found in ...

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 . The eigenfunctions of H contain the influence of exceptional points (EPs) and external mixing (EM) of the states via the ...

Hypothesis Testing with Open Quantum Systems [PDF]
Physical Review Letters, 2015 Using a quantum circuit model we derive the maximal ability to distinguish which of several candidate Hamiltonians describe an open quantum system. This theory, in particular, provides the maximum information retrievable from continuous quantum measurement records, available when a quantum system is perturbatively coupled to a broadband quantized ...

Digital quantum simulation framework for energy transport in an open quantum system
New Journal of Physics, 2020 Quantum effects such as the environment assisted quantum transport (ENAQT) displayed in photosynthetic Fenna–Mathews–Olson (FMO) complex has been simulated on analog quantum simulators.

Open-System Quantum Annealing in Mean-Field Models with Exponential Degeneracy*
Physical Review X, 2016 Real-life quantum computers are inevitably affected by intrinsic noise resulting in dissipative nonunitary dynamics realized by these devices. We consider an open-system quantum annealing algorithm optimized for such a realistic analog quantum device ...

Physical Review Research, 2020 The number of topological defects created in a system driven through a quantum phase transition exhibits a power-law scaling with the driving time. This universal scaling law is the key prediction of the Kibble-Zurek mechanism (KZM), and testing it using

From stochastic Hamiltonian to quantum simulation: exploring memory effects in exciton dynamics
New Journal of PhysicsThe unraveling of open quantum system dynamics in terms of stochastic quantum trajectories offers a picture of open system dynamics that consistently considers memory effects stemming from the finite correlation time of environment fluctuations.

Correlation-Picture Approach to Open-Quantum-System Dynamics
Physical Review X, 2020 We introduce a dynamical picture, referred to as correlation picture, which connects a correlated bipartite state to its uncorrelated counterpart. This picture allows us to derive an exact dynamical equation for a general open-system dynamics with system-
