- Abstract: We report progress in the theory of photoluminescence and light scattering by
two closely spaced particles. This study is based on our original method to
derive the master equation for a system of coupled quantum emitters driven by a
cw laser. We emphasise on the case when the emitters are two-level systems but
notably different in their transition frequencies and transition moments. The
master equation is shown to describe the dipole-dipole coupling and the
cooperative entanglement between the particles naturally. It is provided by the
use of the Bogolyubov-Born-Green-Kirkwood-Yvon (BBGKY) hierarchies for reduced
density matrices and correlation operators of the material and photonic
subsystems. Tackling the hierarchies has also provided us with an elegant way
to calculate the photoluminescence excitation spectra subject to the
arrangement of the excitation and the position of the detector against the
emitters. Our findings may be important for developing novel possibilities for
the all-optical nanoscopy and may help construction of entangled systems to be
implemented in quantum technologies.

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.

Electromagnetically induced transparency (EIT) is a phenomenon that can provide strong and robust interfacing between optical signals and quantum coherence of electronic spins.
We show that EIT can be established with high visibility also in this material platform upon careful design of the measurement geometry.
Our work provides an understanding of EIT in multi-level systems with significant inhomogeneities, and our considerations are valid for a wide array of defects in semiconductors.

We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
