Description
Summary:Quantum emitters in transition metal dichalcogenides (TMDs) have recently emerged as a promising platform for generating single photons for optical quantum information processing. In this work, we present an approach for deterministically controlling the polarization of fabricated quantum emitters in a tungsten diselenide (WSe\(_2\)) monolayer. We employ novel nanopillar geometries with long and sharp tips to induce a controlled directional strain in the monolayer, and we report on fabricated WSe\(_2\) emitters producing single photons with a high degree of polarization \((99\pm 4 \%)\) and high purity (\(g^{(2)}(0) = 0.030 \pm 0.025\)). Our work paves the way for the deterministic integration of TMD-based quantum emitters for future photonic quantum technologies.
