The goal of this Special Topic is to provide new insights in the physics of single quantum emitters and single-photon detectors and their possible use for quantum photonic applications.

Decoherence and spectral diffusion processes in quantum dots, which limit the photon indistinguishability, are considered in their article. In their article, Anderson and others have investigated the noise sources that affect InAs/InP quantum dots emitting in the telecom C-band by comparing their behavior on a wetting layer for Stranski-Krastanov grown quantum dots with a nearly wetting layer-free environment achieved with the droplet epitaxy growth mode. They show that the droplet epitaxy growth mode is beneficial for a low-noise environment, which is a pre-condition for the generation of highly coherent photons.

Abstract

The goal of this Special Topic is to provide new insights in the physics of single quantum emitters and single-photon detectors and their possible use for quantum photonic applications. The perspective article of Vural and others discusses the challenges for multi-source quantum implementations based on self-assembled InGaAs quantum dots. Decoherence and spectral diffusion processes in quantum dots, which limit the photon indistinguishability, are considered in their article. In their article, Anderson and others have investigated the noise sources that affect InAs/InP quantum dots emitting in the telecom C-band by comparing their behavior on a wetting layer for Stranski-Krastanov grown quantum dots with a nearly wetting layer-free environment achieved with the droplet epitaxy growth mode. They show that the droplet epitaxy growth mode is beneficial for a low-noise environment, which is a pre-condition for the generation of highly coherent photons.
