量子增强技术有望突破长基线光学/近红外干涉测量中光子损失和相位误差的限制,通过量子纠缠连接不同望远镜 aperture,实现微弧秒级分辨率的突破。

摘要:

由光学-近红外阵列在千米基线条件下提供的微弧秒级分辨率有望带来科学突破。然而,将弱相干光子态传输这些距离存在重大技术障碍:主要是光子损失和相位误差。量子望远镜利用纠缠态连接空间分离的口径,提供解决光子损失的可能方案。NSF NOIRLab与中心量子网络和亚利桑那州立大学量子倡议合作,发起探索这些概念的倡议。本文简要描述了量子概念,并提出了一条通往量子增强的极长基线光学-近红外干涉测量阵列的技术路线。设想在短基线和有限相位波动条件下,通过最简单的Gottesman协议测量光子空间相干性作为第一步的天基演示。

英文摘要:

Microarcsecond resolutions afforded by an optical-NIR array with kilometer-baselines would enable breakthrough science. However significant technology barriers exist in transporting weakly coherent photon states over these distances: primarily photon loss and phase errors. Quantum telescopy, using entangled states to link spatially separated apertures, offers a possible solution to the loss of photons. We report on an initiative launched by NSF NOIRLab in collaboration with the Center for Quantum Networks and Arizona Quantum Initiative at the University of Arizona, Tucson, to explore these concepts further. A brief description of the quantum concepts and a possible technology roadmap towards a quantum-enhanced very long baseline optical-NIR interferometric array is presented. An on-sky demonstration of measuring spatial coherence of photons with apertures linked through the simplest Gottesman protocol over short baselines and with limited phase fluctuations is envisaged as the first step.
