Obtaining substantial nonlinear effects at the single-photon level is a considerable challenge that holds great potential for quantum optical measurements and information processing. Of the progress that has been made in recent years one of the most promising methods is to scatter coherent light from quantum emitters, imprinting quantum correlations onto the photons. We report effective interactions between photons, controlled by a single semiconductor quantum dot that is weakly coupled to a…

Tunable Photon Statistics Exploiting the Fano Effect in a Waveguide.
TLDR
This model demonstrates that the tunable photon statistics arise from the dependence of the sign of two-photon interference (either constructive or destructive) on the detuning of the input relative to the Fano resonance.

Light Scattering from Solid-State Quantum Emitters: Beyond the Atomic Picture.
TLDR
It is found that even in the presence of a low-Q cavity with high Purcell enhancement, phonon coupling leads to a sideband that is completely insensitive to excitation conditions and to a nonmonotonic relationship between laser detuning and coherent fraction, both of which are major deviations from atomlike behavior.
Measurement-Induced Strong Kerr Nonlinearity for Weak Quantum States of Light.
TLDR
This work coherently combines two sequences of single photon addition and subtraction to induce a nonlinear phase shift at the single photon level and probes the induced nonlinearity with weak coherent states and characterize the output non-Gaussian states with quantum state tomography.

This work reports on the fabrication of ultrabright sources of indistinguishable single photons, thanks to deterministic positioning of single quantum dots in well-designed pillar cavities, and shows that a two-laser excitation scheme allows reducing the fluctuations of the quantum dot electrostatic environment under high pumping conditions.
Nanophotonic quantum phase switch with a single atom
TLDR
By strongly coupling a photon to a single atom trapped in the near field of a nanoscale photonic crystal cavity, this work realizes a system in which a single atoms switches the phase of a photon and a single photon modifies the atom’s phase.

Phase-locked indistinguishable photons with synthesized waveforms from a solid-state source.
TLDR
It is demonstrated that the coherently generated single photons from a single self-assembled InAs quantum dot display mutual coherence with the excitation laser on a timescale exceeding 3 s, and that separate photons generated coherently by the same laser field are fundamentally indistinguishable, lending themselves to the creation of distant entangling through quantum interference.
