Exploiting coherence for quantum thermodynamic advantage
New Journal of Physics, 2022 The introduction of the quantum analogue of a Carnot engine based on a bath comprising of particles with a small amount of coherence initiated an active line of research on the harnessing of different quantum resources for the enhancement of thermal ...

Tensor network simulation of chains of non-Markovian open quantum systems [PDF]
Physical Review Research, 2022 We introduce a general numerical method to compute dynamics and multi-time correlations of chains of quantum systems, where each system may couple strongly to a structured environment.

Quantum dynamics in open quantum-classical systems [PDF]
Journal of Physics: Condensed Matter, 2015 Often quantum systems are not isolated and interactions with their environments must be taken into account. In such open quantum systems these environmental interactions can lead to decoherence and dissipation, which have a marked influence on the properties of the quantum system.

Analog Quantum Simulation of the Dynamics of Open Quantum Systems with Quantum Dots and Microelectronic Circuits [PDF]
PRX Quantum, 2022 We introduce a general setup for the analog quantum simulation of the dynamics of open quantum systems based on semiconductor quantum dots electrically connected to a chain of quantum RLC electronic circuits.

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.

Symmetrized Liouvillian Gap in Markovian Open Quantum Systems. [PDF]
Physical Review Letters, 2022 Markovian open quantum systems display complicated relaxation dynamics. The spectral gap of the Liouvillian characterizes the asymptotic decay rate toward the steady state, but it does not necessarily give a correct estimate of the relaxation time ...

Quantum control theory and applications: A survey [PDF]
, 2010 This paper presents a survey on quantum control theory and applications from a control systems perspective. Some of the basic concepts and main developments (including open-loop control and closed-loop control) in quantum control theory are reviewed.

Simulating open quantum systems with giant atoms [PDF]
Quantum Science and TechnologyOpen quantum many-body systems are of both fundamental and applicational interest. However, it remains an open challenge to simulate and solve such systems, both with state-of-the-art classical methods and with quantum-simulation protocols.

Time-Dependent Variational Principle for Open Quantum Systems with Artificial Neural Networks. [PDF]
Physical Review Letters, 2021 We develop a variational approach to simulating the dynamics of open quantum many-body systems using deep autoregressive neural networks. The parameters of a compressed representation of a mixed quantum state are adapted dynamically according to the ...

Adiabatic Quantum Search in Open Systems [PDF]
, 2016 Adiabatic quantum algorithms represent a promising approach to universal quantum computation. Whilst in a closed system these algorithms are limited by avoided level crossings, where the gap becomes exponentially small in the system size, their ...
