Towards indistinguishable photon generation from nanowire quantum dots
Sayan Gangopadhyay
Nanowire quantum dots are promising candidates as deterministic sources of single and entangled photons. Achieving coherent control of these sources using resonant excitation enables the generation of indistinguishable single photons─a key requirement for quantum interference. However, resonant excitation of nanowire quantum dots has remained a long-standing challenge due to demanding laser suppression requirements. In this talk, I will elaborate on our recent success on resonant excitation of nanowire quantum dots which enabled us to benchmark the single photon indistinguishability from such sources. I will also discuss a theoretical proposal to improve the indistinguishability using a broadband nanophotonic cavity based on interfering resonances in a single dielectric resonator—an approach that has not yet been explored for improving photon indistinguishability at the single-emitter level.
