Dark Matter Searches using Quantum

项目摘要

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本物理面临的最大问题之一。尽管进行了数十年的实验努力，但仍未进行检测，并且常规暗物质模型的可能性正在减少。为了探索新的理论动机模型，需要新的方法。作为Quest-DMC项目的一部分，该提案将利用量子技术来制定一个独特的程序。Quest-DMC项目将宏观量子系统，Superfluid helium-3与最先进的量子技术结合在一起。该目标将用量子设备进行仪器，从而对暗物质相互作用产生高度的敏感性。量子传感器的开发将在伦敦大学皇家霍洛威的超低温度与Astroparpicle组之间进行新的合作。将生成不同类型的量子传感器，进行基准测试和优化，以确定其对暗物质搜索的适用性。也可以通过改变超流体氦3的量子状态来实现暗物质的定向检测。这允许测试可能的暗物质信号的银河系来源。
