研究了半导体量子点中的腔辅助受激拉曼绝热通道(STIRAP)方案,作为产生波形可编程的高质量单光子的途径。这项工作解决了线性量子计算、玻色子采样和量子通信中对高纯度、不可分辨光子的需求。建立了一个基于时间的Maxwell赝自旋模型,研究了在GaAs/AlGaAs微柱腔中,中性InAs量子点中孤立的Λ系统在腔辅助绝热过程中产生单光子的过程.作为一个模型Λ-系统,我们考虑了量子点双激子三重态与暗激子态通过圆偏振脉冲和腔场耦合。我们的模拟演示了通过驱动脉冲特性:形状,持续时间,强度和失谐来控制所发射的单光子脉冲波形。
We investigate cavity-assisted Stimulated Raman Adiabatic passage (STIRAP) schemes in semiconductor quantum dots (QDs) embedded in an optical cavity as a route for generation of high-quality single photons with programmable waveform. This work addresses the need for high-purity, indistinguishable photons in linear quantum computing, boson sampling, and quantum communications. We develop a time-dependent Maxwell-pseudospin model of single-photon generation through cavity-assisted adiabatic passage in a Λ-system isolated in a neutral InAs QD in a realistic GaAs/AlGaAs micropillar cavity. As a model Λ-system, we consider QD biexciton triplet states coupled to dark-exciton states by a circularly polarised pulse and a cavity field. Our simulations demonstrate control of the emitted single-photon pulse waveform by the driving pulse characteristics: shape, duration, intensity and detuning.
