We investigate theoretically the temporal behavior of a quantum dot under off-resonant optical excitation targeted at fast acoustic phonon-assisted state preparation. We demonstrate that in a preparation process driven by short laser pulses three processes can be identified: a dressing of the states during the switch on of the laser pulse, a subsequent phonon-induced relaxation and an undressing at the end of the pulse. By analyzing excitation scenarios with different pulse shapes we highlight…

Phonon-assisted dark exciton preparation in a quantum dot
In semiconductor quantum dots the coupling to the environment, i.e. to phonons, plays a crucial role for optical state preparation. We analyze the phonon impact on two methods for a direct optical
Dynamic vibronic coupling in InGaAs quantum dots [Invited]
The electron–phonon coupling in self-assembled InGaAs quantum dots is relatively weak at low light intensities, which means that the zero-phonon line in emission is strong compared to the phonon
On-demand generation of higher-order Fock states in quantum-dot–cavity systems
The on-demand preparation of higher-order Fock states is of fundamental importance in quantum information sciences. We propose and compare different protocols to generate higher-order Fock states in
Emission-Frequency Separated High Quality Single-Photon Sources Enabled by Phonons.
We demonstrate theoretically that the single-photon purity of photons emitted from a quantum dot exciton prepared by phonon-assisted off-resonant excitation can be significantly higher in a wide
Optical Signals to Monitor the Dynamics of Phonon‐Modified Rabi Oscillations in a Quantum Dot
Semiconductor quantum dots are solid state few‐level systems which can interact strongly with light. As such, they can be used as a single photon source or to perform solid‐state quantum‐optics
Biexciton initialization by two-photon excitation in site-controlled quantum dots: The complexity of the antibinding state case

The quest for the perfect single-photon source includes finding the optimal protocol for exciting the quantum emitter. Coherent optical excitation was, up until now, achieved by tuning the laser

ABSTRACT We review distinct features arising from the unique nature of the carrier-phonon coupling in self-assembled semiconductor quantum dots. Because of the discrete electronic energy structure,

Semiconductor quantum dots in cavities are high-performance single-photon sources. Thus far the most efficient sources utilise resonant excitation of an unpolarized quantum emitter coupled to a
Unidirectional quantum transport in optically driven V -type quantum dot chains
We predict a mechanism for achieving complete population inversion in a continuously driven InAs/GaAs semiconductor quantum dot featuring $V$-type transitions. This highly nonequilibrium steady state
