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 ...

The Schr\"odinger-Langevin equation with and without thermal fluctuations

, 2016
The Schr\"odinger-Langevin (SL) equation is considered as an effective open quantum system formalism suitable for phenomenological applications involving a quantum subsystem interacting with a thermal bath.

A Note on the Relativistic Transformation Properties of Quantum Stochastic Calculus

Entropy
We 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 ...

Open system dynamics with non-Markovian quantum trajectories

, 1998
A non-Markovian stochastic Schroedinger equation for a quantum system coupled to an environment of harmonic oscillators is presented. Its solutions, when averaged over the noise, reproduce the standard reduced density operator without any approximation ...

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 ...

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. Our measure can be defined for quantum discord (QD), geometric quantum discord (GQD), or even by the entanglement of formation (EOF).
