Abstract
QDs are also promising platform for generating polarization-entangled photon pairs based pm the radiative cascades from a biexciton state. Resonant two-photon pumping can deterministically create a biexciton in the QD, enabling on-demand generation of entanglement photon pairs at a high-yield rate[
Since the emission wavelength of QD is determined by the physical size of the confinement potential well, which is extremely hard to control during epitaxial growth or nanohole engineering, a broad inhomogeneous distribution of photon energy is expected from an ensemble of QDs, which can be troublesome for applications requiring single photons to be indistinguishable. In addition, the shallow carrier confinement in As-based QDs limits their operation temperature to cryogenic one, rendering them cumbersome and economically unfriendly for applications in the field of quantum information processing (QIP).
Recently, the discoveries of room-temperature optically-active emitters in standard GaN thin films with an emission wavelengths covering 1.1–1.4 μm range[
SiC-based single-photon emitters (SPEs) also captures significant amount of attention recently, thanks to the progress on silicon vacancies VSi and di-vacancy VSiVC defects, which have been found to be optically addressable on single defect level and behave as single photon emitters[
