We calculate the resonance fluorescence signal of a two-level system coupled to a quantized phonon mode. By treating the phonons in the independent boson model and not performing any approximations in their description, we also have access to the state evolution of the phonons. We confirm the validity of our model by simulating the limit of an initial quasi-classical coherent phonon state, which can be compared to experimentally confirmed results in the semiclassical limit. In addition we…

Influence of excited state decay and dephasing on phonon quantum state preparation
The coupling between single-photon emitters and phonons opens many possibilities to store and transmit quantum properties. In this paper we apply the independent boson model to describe the coupling
Quantum dot cavity-QED in the presence of strong electron-phonon interactions
A quantum dot strongly coupled to a single high-finesse optical microcavity mode constitutes a new fundamental system for quantum optics. Here, the effect of exciton-phonon interactions on reversible
Electron-phonon interaction in quantum dots: A solvable model
The relaxation of electrons in quantum dots via phonon emission is hindered by the discrete nature of the dot levels (``phonon bottleneck''). In order to clarify the issue theoretically we consider a
Antibunching of thermal radiation by a room-temperature phonon bath: a numerically solvable model for a strongly interacting light-matter-reservoir system.
This work presents a numerically solvable model for the combined electron, photon, and phonon dynamics, which reproduces the Jaynes-Cumming solution and interaction with a phonon bath leads to a higher value for the intensity-intensity correlation function.
Optically driven quantum dots as source of coherent cavity phonons: a proposal for a phonon laser scheme.
This scheme for the creation of nonequilibrium phonons is robust with respect to radiative and phononic damping and only requires optical Rabi frequencies of the order of the electron-phonon coupling strength.
Coherent control of phonon quantum beats
Abstract The coherent control of excitons coupled to longitudinal optical phonons is analyzed in the quantum kinetic regime. Different models allowing for different levels of sophistication in the
Phonon-assisted transitions from quantum dot excitons to cavity photons
For a single semiconductor quantum dot embedded in a microcavity, we theoretically and experimentally investigate phonon-assisted transitions between excitons and the cavity mode. Within the

The pure dephasing of the optical polarization and the corresponding line shape of absorption spectra in small quantum dots due to the interaction of the exciton both with optical and acoustic
Quantum control of surface acoustic-wave phonons
Full quantum control of the mechanical state of a macroscale mechanical resonator is demonstrated and a non-classical superposition of zero- and one-phonon mechanical Fock states is generated and measured by strongly coupling a surface acoustic-wave resonator to a superconducting qubit.
Laser cooling of a nanomechanical resonator mode to its quantum ground state.
It is shown that it is possible to cool a nanomechanical resonator mode to its ground state through resonant laser excitation of a phonon sideband of an embedded quantum dot.
