Abstract

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 (WSe2) 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 WSe2 emitters producing single photons with a high degree of polarization (99 ± 4%) and high purity (g(2)(0) = 0.030 ± 0.025). Our work paves the way for the deterministic integration of TMD-based quantum emitters for future photonic quantum technologies.

通过确定性应变工程定制 WSe2 量子发射器中的极化

过渡金属二掺杂物（TMDs）中的量子发射器近来已成为产生用于光量子信息处理的单光子的一个前景广阔的平台。在这项工作中，我们提出了一种确定性控制二硒化钨（WSe2）单层中制造的量子发射器偏振的方法。我们采用了新颖的纳米柱几何结构，其尖端又长又尖，可在单层中诱导可控的定向应变。我们报告了制造的 WSe2 发射器，其产生的单光子具有高度极化（99 ± 4%）和高纯度（g(2)(0) = 0.030 ± 0.025）。我们的工作为未来光子量子技术中基于 TMD 的量子发射器的确定性集成铺平了道路。
