Colloidal quantum dots as single photon sources

Abstract

Single photon sources (SPSs) are key components in various developing applications, such as quantum cryptography, optical quantum computation, and quantum sensing. Colloidal quantum dots (CQDs) have emerged as an attractive material for SPSs due to their solution-based processing, narrow and tunable photoluminescence (PL) wavelength, high quantum yield (QY), and integration with different substrates. In this paper, we will review the current state of research on using CQDs for SPSs, including the various methods for improving the optical properties of CQDs, the diverse types of CQDs that have been used as SPSs, and the nanophotonic approaches used to improve the single photon properties of CQDs. Additionally, we will discuss the challenges and future directions for the field.
