@article{Predojevi2015ResonantEA, title={Resonant Excitation and Photon Entanglement from Semiconductor Quantum Dots}, author={Ana Predojevi{\vc}}, journal={arXiv: Quantum Physics}, year={2015}, pages={303-324} }

In this chapter we review the use of semiconductor quantum dots as sources of quantum light. Principally, we focus on resonant two-photon excitation, which is a method that allows for on-demand generation of photon pairs. We explore the advantages of resonant excitation and present a number of results that were made in this excitation regime. In particular, we cover the following topics: photon statistics, coherent manipulation of the ground-excited state superposition, and generation of time…
