Resonance fluorescence in the Heitler regime provides access to single photons with coherence well beyond the Fourier transform limit of the transition, and holds the promise to circumvent environment-induced dephasing common to all solid-state systems. Here we demonstrate 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. Exploiting this degree of mutual coherence, we… 
Near-Transform-Limited Single Photons from an Efficient Solid-State Quantum Emitter.
TLDR
A temporal and spectral analysis reveals the pulsed resonance fluorescence single photons are close to the transform limit, which are readily useful for multiphoton entanglement and interferometry experiments.
Indistinguishable single photons with flexible electronic triggering
A key ingredient for quantum photonic technologies is an on-demand source of indistinguishable single photons. State-of-the-art indistinguishable single-photon sources typically employ resonant
Generation of single photons with highly tunable wave shape from a cold atomic ensemble
TLDR
A heralded single photon source with controllable emission time based on a cold atomic ensemble, which can generate photons with temporal durations varying over three orders of magnitude up to 10 μs without a significant change of the readout efficiency is reported.
Suppressing Spectral Diffusion of Emitted Photons with Optical Pulses.
TLDR
This paper shows that a sequence of optical pulses applied to the solid-state emitter can stabilize the emission line at the desired frequency and provides a simple and robust way to greatly improve the efficiency of photon-mediated entanglement and/or coupling to photonic cavities for solid- state qubits.
Fundamental Limits to Coherent Photon Generation with Solid-State Atomlike Transitions.
TLDR
It is observed that the coupling of the atomiclike transitions to the vibronic transitions of the crystal lattice is independent of the driving strength, even for detuned excitation using the spin-Λ configuration.
Temporal shaping of single-photon pulses
The ability to control the temporal shape of single-photon pulses is highly desirable in quantum information processing. For instance, it has been shown that Gaussian pulses are best suited for
Transform-limited single photons from a single quantum dot
TLDR
Transform-limited linewidths measured on second timescales are reported, primarily on the neutral exciton but also on the charged exciton close to saturation.
Generation of frequency sidebands on single photons with indistinguishability from quantum dots
Generation and manipulation of the quantum state of a single photon is at the heart of many quantum information protocols. There has been growing interest in using phase modulators as quantum optics
Generation of non-classical light in a photon-number superposition
The ability to generate light in a pure quantum state is essential for advances in optical quantum technologies. However, obtaining quantum states with control in the photon-number has remained
Photon Noise Suppression by a Built-in Feedback Loop.
TLDR
A built-in stabilization approach for the photon stream, which relies solely on charge carrier dynamics of a two-dimensional hole gas inside a micropillar structure, which represents an easy way for photon noise suppression in large arrays of single photon emitters and promises to reach higher bandwidth by device optimization.

Post-selected indistinguishable photons from the resonance fluorescence of a single quantum dot in a microcavity.
TLDR
A strictly resonant continuous-wave excitation together with controlling the spontaneous emission lifetime of the single quantum dots via tunable emitter-mode coupling (Purcell) is proven as a versatile scheme to generate close to Fourier transform-limited (T2/(2T1)=0.91) single photons even at 80% of the emission saturation level.
