摘要:

月球永久阴影区(PSRs)是太阳系中最冷的地区之一,预计将成为未来国际航天机构任务的关键着陆点。它们靠近持续太阳能峰值和潜在资源丰富,使其成为月球探索和未来月球基地的首选目标。本文提出在这些区域部署一个被动的超稳定光学谐振腔,将使激光系统具有前所未有的相位相干性。月球PSR独特的物理环境极大地促进了低温单片硅谐振腔的建设,该谐振腔表现出低10^-18热噪声限稳定性,相干时间超过1分钟,比当前最好的地面系统好一个数量级。这种稳定的激光器将为太空中的量子技术基础设施奠定基础,可用于建立月球时间标准、构建长基线光学干涉仪、在卫星网络中分布稳定的光学信号、测试广义相对论和引力物理,以及构建空间量子网络的骨干。

英文摘要:

The Moon's permanently shadowed regions (PSRs) are among the coldest places in the Solar System and are expected to become key landing sites for upcoming international space agency missions. Their proximity to peaks of perpetual solar power and potential resource richness makes them prime candidates for lunar exploration and future Moon bases. Here we propose to deploy a passive, ultrastable optical resonator in these regions that will enable laser systems with unprecedented phase-coherence. The unique physical environment of lunar PSRs greatly benefits the construction of a cryogenic monolithic silicon cavity that exhibits low $10^{-18}$ thermal noise-limited stability and coherence time exceeding 1 minute, more than a decade better than the current best terrestrial system. Such a stable laser will form an enabling infrastructure for quantum technology in space to serve many applications, including establishing a lunar time standard, building long-baseline optical interferometry, distribution of stable optical signals across networks of satellites, testing general relativity and gravitational physics, and forming the backbone for space-based quantum networks.
