The nature of dark matter is one of the biggest problems facing fundamental physics today. Despite several decades of experimental effort no detection has been made and the possibilities for conventional dark matter models are decreasing. In order to explore new theoretically motivated models new approaches are needed. This proposal will develop a unique programme utilising quantum technology to search for low mass dark matter, as part of the QUEST-DMC project.The QUEST-DMC project combines a macroscopic quantum system, superfluid helium-3, with state-of-the art quantum technologies. The target will be instrumented with quantum devices, giving high sensitivity to dark matter interactions. Quantum sensor development will be carried out in a new collaboration between the Ultra-Low Temperature and Astroparticle groups at Royal Holloway, University of London. Different types of quantum sensors will be produced, benchmarked and optimised in order to determine their suitability for a dark matter search. Directional detection of dark matter may also be achieved by altering the quantum state of the superfluid helium-3. This allows a test of the galactic origin of a possible dark matter signal.

暗物质的性质是当今基础物理学面临的最大问题之一。尽管进行了数十年的实验努力，但仍未进行任何检测，并且传统暗物质模型的可能性正在减少。为了探索新的理论驱动模型，需要新的方法。作为 QUEST-DMC 项目的一部分，该提案将开发一个利用量子技术寻找低质量暗物质的独特程序。QUEST-DMC 项目将宏观量子系统、超流氦 3 与最先进的技术相结合量子技术。该目标将配备量子设备，对暗物质相互作用具有高灵敏度。量子传感器的开发将由伦敦大学皇家霍洛威学院超低温和天体粒子小组之间的新合作进行。将生产、基准测试和优化不同类型的量子传感器，以确定它们是否适合暗物质搜索。暗物质的定向探测也可以通过改变超流氦 3 的量子态来实现。这可以测试可能的暗物质信号的银河起源。
