Hamiltonian open quantum system toolkit

Communications Physics, 2022
In quantum computing, simulating continuously evolving open quantum systems is key to describe dynamical processes on noisy quantum devices. Here, the authors present an open-source software package “Hamiltonian Open Quantum System Toolkit” (HOQST) for ...

Simulating open quantum systems with giant atoms [PDF]

Quantum Science and Technology
Open 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.

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 ...

In situ upgrade of quantum simulators to universal computers [PDF]

, 2018
Quantum simulators, machines that can replicate the dynamics of quantum systems, are being built as useful devices and are seen as a stepping stone to universal quantum computers.

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 ...

Explaining the Unobserved: Why Quantum Mechanics Is Not only About Information [PDF]

, 2005
A remarkable theorem by Clifton, Bub and Halverson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance of the theorem is that quantum theory should be ...

Efficient Exploration of Hamiltonian Parameter Space for Optimal Control of Non-Markovian Open Quantum Systems. [PDF]

Physical Review Letters, 2021
We present a general method to efficiently design optimal control sequences for non-Markovian open quantum systems, and illustrate it by optimizing the shape of a laser pulse to prepare a quantum dot in a specific state.

Simulating open quantum systems with trapped ions

, 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.

Modulating thermal robustness and entanglement distribution in a two-dimensional dissipative spin system using impurities

Results in Physics, 2022
We consider a finite two-dimensional Heisenberg triangular spin lattice coupled to a dissipative Markovian environment at finite temperature in the presence of an external uniform magnetic field.
