Bottomonium observables in an open quantum system using the quantum trajectories method [PDF]
EPJ Web of Conferences, 2022 We solve the Lindblad equation describing the Brownian motion of a Coulombic heavy quark-antiquark pair in a strongly coupled quark gluon plasma using the Monte Carlo wave function method. The Lindblad equation has been derived in the framework of pNRQCD

Using the Environment to Understand non-Markovian Open Quantum Systems [PDF]
Quantum, 2021 Tracing out the environmental degrees of freedom is a necessary procedure when simulating open quantum systems. While being an essential step in deriving a tractable master equation it represents a loss of information. In situations where there is strong

Separability and distillability in composite quantum systems -a primer- [PDF]
, 2000 Quantum mechanics is already 100 years old, but remains alive and full of challenging open problems. On one hand, the problems encountered at the frontiers of modern theoretical physics like Quantum Gravity, String Theories, etc.

Simulation of open quantum systems by automated compression of arbitrary environments [PDF]
Nature Physics, 2021 Studies of the dynamics of open quantum systems are limited by the large Hilbert space of typical environments, which is too large to be treated exactly.

Digital Simulation of Single Qubit Markovian Open Quantum Systems: A Tutorial
Quanta, 2023 One of the first proposals for the use of quantum computers was the simulation of quantum systems. Over the past three decades, great strides have been made in the development of algorithms for simulating closed quantum systems and the more complex open
