Time crystallinity in open quantum systems [PDF]
Quantum, 2020 Time crystals are genuinely non-equilibrium quantum phases of matter that break time-translational symmetry. While in non-equilibrium closed systems time crystals have been experimentally realized, it remains an open question whether or not such a phase ...

Localization in Open Quantum Systems [PDF]
Physical Review Letters, 2017 In an isolated single-particle quantum system a spatial disorder can induce Anderson localization. Being a result of interference, this phenomenon is expected to be fragile in the face of dissipation. Here we show that dissipation can drive a disordered system into a steady state with tunable localization properties.

Open quantum systems for quarkonia [PDF]
International Journal of Modern Physics A, 2021 I review recent applications of the open quantum system framework in the understanding of quarkonium suppression in heavy-ion collisions, which has been used as a probe of the quark–gluon plasma for decades. The derivation of the Lindblad equations for quarkonium in both the quantum Brownian motion and the quantum optical limits and their ...

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

A study of quantum correlations in open quantum systems [PDF]
Quantum Information and Computation, 2011 In this work, we study quantum correlations in mixed states. The states studied are modeled by a two-qubit system interacting with its environment via a quantum non demolition (purely dephasing) as well as dissipative type of interaction. The entanglement dynamics of this two qubit system is analyzed.

Entanglement Degradation in Two Interacting Qubits Coupled to Dephasing Environments
Entropy, 2023 One of the main obstacles toward building efficient quantum computing systems is decoherence, where the inevitable interaction between the qubits and the surrounding environment leads to a vanishing entanglement.

Identifiability of open quantum systems [PDF]
Physical Review A, 2014 We provide a general framework for the identification of open quantum systems. By looking at the input-output behavior, we try to identify the system inside a black box in which some Markovian time-evolution takes place. Due to the generally irreversible nature of the dynamics, it is difficult to assure full controllability over the system.

Simulating open quantum systems with trapped ions [PDF]
, 2005 This paper focuses on the possibility of simulating the open system dynamics of a paradigmatic model, namely the damped harmonic oscillator, with single trapped ions. The key idea consists in using a controllable physical system, i.e.
