论文摘要
单光子检测器在几种基础科学和技术应用中起关键作用。尽管在提高性能方面取得了进展,但仍缺乏可以保持高性能的同时解决光子频率的单个光子探测器。通过量子模拟,我们表明纳米级元件与光电探测器结构中的光子场合相互作用可以同时实现高效率,低抖动和高频分辨率。我们讨论了这种合作互动对于达到这种绩效制度的必不可少的,分析了影响指标之间绩效和权衡的因素。我们说明了在可见范围内1 eV带宽上频率分辨率的潜在性能,这表明几乎完美的检测效率,几百个飞秒的抖动以及数十MEV的频率分辨率。最后,基于用量子点功能化功能化的碳纳米管,提出了这种体系结构的潜在物理实现。
Single photon detectors play a key role across several basic science and technology applications. While progress has been made in improving performance, single photon detectors that can maintain high performance while also resolving the photon frequency are still lacking. By means of quantum simulations, we show that nanoscale elements cooperatively interacting with the photon field in a photodetector architecture allow to simultaneously achieve high efficiency, low jitter, and high frequency resolution. We discuss how such cooperative interactions are essential to reach this performance regime, analyzing the factors that impact performance and trade-offs between metrics. We illustrate the potential performance for frequency resolution over a 1 eV bandwidth in the visible range, indicating near perfect detection efficiency, jitter of a few hundred femtoseconds, and frequency resolution of tens of meV. Finally, a potential physical realization of such an architecture is presented based on carbon nanotubes functionalized with quantum dots.
