We investigate the non-Markovian dynamics of an open Ising model simulated by a superconducting circuit. The quantum many-body system is weakly coupled to a white, pink- or blue-colored environment. The relaxation of the system in the strong inter-qubit interaction regime shows a metastable behaviour. In comparison with the dissipative system in the Markovian limit, the negative memory of the blue-colored noise weakens the system's relaxation. However, for the pink-colored noise the relaxation…

Non-Markovian decoherence of a two-level system in a Lorentzian bosonic reservoir and a stochastic environment with finite correlation time

In this paper we investigate non-Markovian evolution of a two-level system (qubit) in a bosonic bath under influence of an external classical fluctuating environment. The interaction with the bath has

From the open generalized Heisenberg model to the Landau–Lifshitz equation

Magnetic systems can be described by the classical Landau–Lifshitz (LL) equation or the fully quantum open generalized Heisenberg model. Using the Lindblad master equation and the mean-field

We propose a scheme of exploring the kinetic properties of the receptor-ligand binding process by means of the frequency stability measurement of a whispering-gallery-mode optical microcavity. In



Quantum critical probing and simulation of colored quantum noise

We propose a protocol to simulate the evolution of a non-Markovian open quantum system by considering a collisional process with a many-body system, which plays the role of an environment. As a

Quantum Simulation of Generic Many-Body Open System Dynamics Using Classical Noise.

A scheme for the quantum simulation of many-body decoherence based on the unitary evolution of a stochastic Hamiltonian is introduced and it is shown that the noise-averaged density matrix simulates an effectively open dynamics governed by k-body Lindblad operators.

Relaxation of Rabi dynamics in a superconducting multiple-qubit circuit

Many-body quantum trajectories of non-Markovian open systems

A long-standing open problem in non-Markovian quantum state diffusion (QSD) approach to open quantum systems is to establish the non-Markovian QSD equations for multiple qubit systems. In this paper,

Open system dynamics with non-Markovian quantum jumps

We discuss in detail how non-Markovian open system dynamics can be described in terms of quantum jumps [J. Piilo et al., Phys. Rev. Lett. 100, 180402 (2008)]. Our results demonstrate that it is

Quantum memories based on engineered dissipation

Storing quantum information for long times without disruptions is a major requirement for most quantum information technologies. A very appealing approach is to use self-correcting Hamiltonians, that

This approach is a generalization of the standard Monte Carlo wave function method for Markovian dynamics and provides an efficient unraveling of the ensemble dynamics of open quantum systems that interact with structured reservoirs.
