Abstract

The Deep Space Quantum Link (DSQL) is a space-mission concept that aims to explore the interplay between general relativity and quantum mechanics using quantum optical interferometry. This mission concept was formally presented to the United States National Academy of Science Decadal Survey as a research campaign for Fundamental Physics in 2022. Since then, advances have been made in the space-based quantum optical technologies required to conduct a DSQL-type mission. In addition, other research efforts have defined alternative measurement concepts to explore the same scientific questions motivating the DSQL mission. This paper serves as an update to the community on the status of the DSQL mission concept and related research and technology development efforts.

通过量子光学干涉测量实现广义相对论和量子力学相结合的卫星测试：深空量子链路的进展

深空量子链路（DSQL）是一个太空任务概念，旨在利用量子光学干涉测量法探索广义相对论和量子力学之间的相互作用。这一任务概念于2022年正式提交给美国国家科学院十年调查，作为基础物理学的一项研究活动。从那时起，执行dsql类型任务所需的天基量子光学技术取得了进展。此外，其他研究工作已经定义了替代度量概念，以探索激发DSQL任务的相同科学问题。本文是DSQL任务概念以及相关研究和技术开发工作的最新情况。

期刊介绍： Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. EPJ Quantum Technology covers theoretical and experimental advances in subjects including but not limited to the following: Quantum measurement, metrology and lithography Quantum complex systems, networks and cellular automata Quantum electromechanical systems Quantum optomechanical systems Quantum machines, engineering and nanorobotics Quantum control theory Quantum information, communication and computation Quantum thermodynamics Quantum metamaterials The effect of Casimir forces on micro- and nano-electromechanical systems Quantum biology Quantum sensing Hybrid quantum systems Quantum simulations.
