Abstract

This paper presents a theoretical study of the enhancement of Zou-Wang-Mandel (ZWM) interferometry through cavity-enhanced spontaneous parametric down-conversion (SPDC) processes producing frequency-entangled biphotons. The ZWM interferometry shows the capability to generate interference effects between single signal photons via indistinguishability between the entangled idler photons. This paper extends the foundational principles of ZWM interferometry by integrating cavity-enhanced SPDCs, aiming to narrow photon bandwidths for improved coherence and photon pair generation efficiency, which is critical for applications in quantum information technologies, quantum encryption, and quantum imaging. This work explores the theoretical implication of employing singly resonant optical parametric oscillators within the ZWM interferometer to produce narrow-band single photons. By combining cavity-enhanced SPDCs with ZWM interferometry, this study fills a gap in current theoretical proposals, offering significant advancements in quantum cryptography and network applications that require reliable, narrow-band single photons.

无诱导发射的腔体增强诱导相干

本文介绍了通过产生频率纠缠双光子的空穴增强自发参量下变频（SPDC）过程来增强邹-王-曼德尔（ZWM）干涉测量法的理论研究。ZWM 干涉测量法显示了通过纠缠惰光子之间的不可分性在单个信号光子之间产生干涉效应的能力。本文扩展了 ZWM 干涉测量法的基本原理，集成了空腔增强 SPDC，旨在缩小光子带宽以提高相干性和光子对生成效率，这对于量子信息技术、量子加密和量子成像等应用至关重要。这项研究探索了在 ZWM 干涉仪中采用单谐振光参量振荡器产生窄带单光子的理论含义。通过将空腔增强 SPDC 与 ZWM 干涉测量相结合，这项研究填补了当前理论提案的空白，为需要可靠窄带单光子的量子密码学和网络应用提供了重大进展。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
