This technique demonstrates efficient coupling of colloidal quantum dots in plasmonic nanocavities, suggesting advancements for quantum computing applications.
Here we will discuss a technique to create arrays of colloidal quantum dots in plasmonic nanocavities through the use of electron beam lithography for use in quantum computing and information processing. Characterizations include photoluminescence and cavity resonance studies, alongside g(2) measurements to estimate the number of coupled emitters at different spots within the array. Deterministic coupling of few and single emitters to nanophotonic structures could pave a way for integrated quantum photonics on-chip.
