00925njm 22002777a 4500 dc Lozano Martín, Lidia author 2023-07-10 Photon antibunching is a fundamental quantum phenomenon in the field of quantum optics, which plays a crucial role in quantum information and telecommunication applications. The aim of this project is to design and implement from scratch the experimental setup to measure antibunching behaviour in quantum dots. The intended purpose is to make this setup accessible to future students of the Quantum Science and Technology master's laboratory by the upcoming year. In this study, we investigate CdSe/ZnS quantum dots as single-photon emitters, a versatile semiconductor nanocrystal that facilitates the measurement of quantum correlations. The initial step involves characterizing the quantum dot to determine the necessary parameters for designing the optical system. Successful execution of this experiment will provide students with enhanced comprehension of the optical properties of quantum dots and the sub-Poissonian statistics governing photon antibunching phenomena.
