Quantum Coding Transitions in the Presence of Boundary Dissipation [PDF]
PRX Quantum, 2023 We investigate phase transitions in the encoding of quantum information in a quantum many-body system due to the competing effects of unitary scrambling and boundary dissipation. Specifically, we study the fate of quantum information in a one-dimensional

Quantum dissipation in a scalar field theory with gapped momentum states. [PDF]
Sci Rep, 2019 Understanding quantum dissipation is important from both theoretical perspective and applications. Here, we show how to describe dissipation in a scalar field theory.

From Non-Hermitian Linear Response to Dynamical Correlations and Fluctuation-Dissipation Relations in Quantum Many-Body Systems [PDF]
PRX Quantum, 2022 Quantum many-body systems are characterized by their correlations. While equal-time correlators and unequal-time commutators between operators are standard observables, the direct access to unequal-time anti-commutators poses a formidable experimental ...

Dissipation-induced enhancement of quantum fluctuations [PDF]
New Journal of Physics, 2016 We study a quantum harmonic oscillator linearly coupled through the position operator $\hat{q}$ to a first bath and through the momentum operator $\hat{p}$ to a second bath yielding an Ohmic–Drude dissipation.

Quantum bounds and fluctuation-dissipation relations [PDF]
SciPost Physics, 2022 In recent years, there has been intense attention on the constraints posed by quantum mechanics on the dynamics of the correlation at low temperatures, triggered by the postulation and derivation of quantum bounds on the transport coefficients or on ...

Dissipation as a resource for Quantum Reservoir Computing [PDF]
Quantum, 2022 Dissipation induced by interactions with an external environment typically hinders the performance of quantum computation, but in some cases can be turned out as a useful resource.

Interacting lattice systems with quantum dissipation: a quantum Monte Carlo study [PDF]
, 2018 Quantum dissipation arises when a large system can be split in a quantum system and an environment where the energy of the former flows to. Understanding the effect of dissipation on quantum many-body systems is of particular importance due to its ...

QUANTUM DISSIPATION AND QUANTUM NOISE [PDF]
Annals of Physics, 1995 We derive the exact action for a damped mechanical system ( and the special case of the linear oscillator) from the path integral formulation of the quantum Brownian motion problem developed by Schwinger and by Feynman and Vernon.

QUANTUM DISSIPATION AND QUANTUM GROUPS [PDF]
Annals of Physics, 1995 We discuss the r\^ole of quantum deformation of Weyl-Heisenberg algebra in dissipative systems and finite temperature systems. We express the time evolution generator of the damped harmonic oscillator and the generator of thermal Bogolubov ...
