摘要:

探测非经典光是光子学量子技术的核心要求。无与伦比的高效率和低暗计数使超导纳米线单光子探测器(SNSPDs)成为光纤和集成光子学应用的主导探测器技术。然而,核心挑战在于如何将其集成到光子集成电路中,而不受限于材料平台或表面形貌。在此,我们提出一种基于转移打印的方法,克服了这些限制,可将SNSPDs集成到任意光子基底上。我们通过将SNSPDs集成到商用制造的绝缘体上硅和绝缘体上铌酸锂集成光子电路中,并展示波导内单光子探测来证明这一点。该方法消除了高质量单光子探测器集成的瓶颈,使其成为可扩展量子信息处理的通用且易用的构建模块。

英文摘要:

Detecting non-classical light is a central requirement for photonics-based quantum technologies. Unrivaled high efficiencies and low dark counts have positioned superconducting nanowire single photon detectors (SNSPDs) as the leading detector technology for fiber and integrated photonic applications. However, a central challenge lies in their integration within photonic integrated circuits regardless of material platform or surface topography. Here, we introduce a method based on transfer printing that overcomes these constraints and allows for the integration of SNSPDs onto arbitrary photonic substrates. We prove this by integrating SNSPDs and showing through-waveguide single-photon detection in commercially manufactured silicon and lithium niobate on insulator integrated photonic circuits. Our method eliminates bottlenecks to the integration of high-quality single-photon detectors, turning them into a versatile and accessible building block for scalable quantum information processing.
