- Abstract summary: phononic excitations constitute a useful interaction channel in hybrid quantum systems.
Light-scattering properties of a single-photon emitter and sidebands in resonance fluorescence spectra can be utilized for acousto-optical transduction.
It is shown that the readout is faulty in situations where relevant resonant transitions are forbidden due to vanishing Franck-Condon factors.

- Abstract: In today's development of quantum technologies a hybrid integration of
phononic excitations becomes increasingly attractive. As natural quasi-particle
excitations in solid state systems, phonons couple to virtually any other
excitation and therefore constitute a useful interaction channel between
different building blocks in hybrid quantum systems. This work explores how the
efficient light-scattering properties of a single-photon emitter and the
appearance of characteristic sidebands in resonance fluorescence spectra, when
interfaced with an arbitrary phonon quantum state, can be utilized for
acousto-optical transduction. Within reasonable approximations, an analytical
description for the optical spectra in the low excitation limit is developed
which can be used to read the number statistics of the initial phonon state
from a given spectrum. It is shown that the readout is faulty in situations
where relevant resonant transitions are forbidden due to vanishing
Franck-Condon factors, especially when considering spectra with a noisy
background. Two possible solutions to this problem are presented: (A) changing
the detuning of the laser relative to the single-photon emitter which modifies
the relevant resonant transitions, or (B) increasing dissipation of the
single-photon emitter to promote off-resonant transitions.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

spectroscopy [0.0]
The radiative quantum cascade, i.e. the consecutive emission of photons from a ladder of energy levels, is of fundamental importance in quantum optics.
Here, we use exciton polaritons to explore the cascaded emission of photons in the regime where individual transitions of the ladder are not resolved.
Remarkably, the measured photon-photon correlations exhibit a strong dependence on the polariton energy, and therefore on the underlying polaritonic interaction strength.
