Abstract.We study the asymptotic dynamics of a driven spin-boson system where the environment is formed by a broadened localized mode. Upon exploiting an exact mapping, an equivalent formulation of the problem in terms of a quantum two-state system (qubit) coupled to a harmonic oscillator which is itself Ohmically damped, is found. We calculate the asymptotic population difference of the two states in two complementary parameter regimes. For weak damping and low temperature, a perturbative… 

Quantum dynamics of a two-level system in a structured environment: Numerical study beyond perturbation theory

The dissipative quantum dynamics of a two-level system interacting with a structured reservoir consisting of a damped harmonic mode is investigated by means of the numerically exact path integral

We study the dissipative dynamics of a biased two-level system (TLS) coupled to a harmonic oscillator (HO), the latter interacting with an Ohmic environment. Using the Van Vleck perturbation theory

Non-markovian dynamics of a biased qubit coupled to a structured bath.

A new analytical approach, beyond the rotating wave approximation, based on unitary transformations and the non-Markovian master equation for the density operator, is applied to treat the biased

Dynamics of a qubit coupled to a broadened harmonic mode at finite detuning

We study the dynamics of a symmetric two-level system strongly coupled to a broadened harmonic mode. Upon mapping the problem on to a spin–boson model with peaked spectral density, we show how

We consider the dissipative dynamics of a qubit coupled to a nonlinear oscillator (NO) embedded in an Ohmic environment. By treating the nonlinearity up to first order and applying Van Vleck

The Dissipative Two-State System

The effect of decoherence in a two-state system (TSS) coupled to its environment hampers the use of the TSSs as qubits in quantum computation. The search for novel ways of realizing this coupling

A novel method is introduced in order to treat the dissipative dynamics of quantum systems interacting with a bath of classical degrees of freedom. The method is based upon an extension of the



Entanglement spectroscopy of a driven solid-state qubit and its detector.

We study the asymptotic dynamics of a driven quantum two-level system coupled via a quantum detector to the environment. We find multiphoton resonances which are due to the entanglement of the qubit

Theoretical analysis of continuously driven dissipative solid-state qubits

We study a realistic model for driven qubits using the numerical solution of the Bloch-Redfield equation as well as analytical approximations using a high-frequency scheme. Unlike in idealized

Coherent dynamics of a flux qubit coupled to a harmonic oscillator

This work demonstrates entanglement between a superconducting flux qubit and asuperconducting quantum interference device (SQUID), which provides the measurement system for detecting the quantum states and an effective inductance that, in parallel with an external shunt capacitance, acts as a harmonic oscillator.

A nanometre-scale superconducting electrode connected to a reservoir via a Josephson junction constitutes an artificial two-level electronic system: a single-Cooper-pair box. The two levels consist
