Thermodynamics and Fluctuation Theorems for a Strongly Coupled Open Quantum System: An Exactly Solvable Case

, 2009
We illustrate recent results concerning the validity of the work fluctuation theorem in open quantum systems [M. Campisi, P. Talkner, and P. H\"{a}nggi, Phys. Rev. Lett.

Efficient simulation of finite-temperature open quantum systems [PDF]

, 2019
Chain-mapping techniques in combination with the time-dependent density matrix renormalization group are a powerful tool for the simulation of open-system quantum dynamics.

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

Targeting qubit states using open-loop control [PDF]

, 2003
We present an open-loop (bang-bang) scheme which drives an open two-level quantum system to any target state, while maintaining quantum coherence throughout the process.

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.

Transitionless quantum driving in open quantum systems

New Journal of Physics, 2014
We extend the concept of superadiabatic dynamics, or transitionless quantum driving, to quantum open systems whose evolution is governed by a master equation in the Lindblad form.

Simulation of open-quantum-system dynamics using the quantum Zeno effect

Physical Review Research, 2020
We suggest a quantum simulator that allows to study the role of memory effects in the dynamics of open quantum systems. A particular feature of our simulator is the ability to engineer both Markovian and non-Markovian dynamics by means of quantum ...

Phase rigidity and avoided level crossings in the complex energy plane [PDF]

, 2006
We consider the effective Hamiltonian of an open quantum system, its biorthogonal eigenfunctions $\phi_\lambda$ and define the value $r_\lambda = (\phi_\lambda|\phi_\lambda)/$ that characterizes the phase rigidity of the eigenfunctions $\phi_\lambda$. In

Assisted quantum simulation of open quantum systems

iScience, 2023
Universal quantum algorithms (UQA) implemented on fault-tolerant quantum computers are expected to achieve an exponential speedup over classical counterparts. However, the deep quantum circuits makes the UQA implausible in the current era. With only the noisy intermediate-scale quantum (NISQ) devices in hand, we introduce the quantum-assisted quantum ...
