Abstract

We report an axion dark matter search with a haloscope equipped with a microwave photon counter. The haloscope is a tunable high quality factor three-dimensional microwave cavity placed in a magnetic field. The photon counter, operated cyclically, maps an incoming microwave photon onto the state of a superconducting transmon qubit. The measurement protocol continuously monitors the power emitted by the haloscope cavity as well as the dark count background and enables tuning of the cavity frequency to probe different axion masses. With this apparatus, we enhance by a factor of 20 the search speed that can be reached with quantum-limited linear amplifiers and set a new standard for probing the existence of axions with resonant detectors above 5 GHz.

基于transmon的单微波光子计数器对轴子暗物质的量子增强传感

我们报告用一个装有微波光子计数器的光镜进行轴子暗物质搜索。光晕镜是放置在磁场中的可调谐高品质因子三维微波腔。周期性操作的光子计数器将进入的微波光子映射到超导传输量子比特的状态上。测量方案连续监测光晕腔发射的功率以及暗计数背景，并能够调整腔频率以探测不同的轴子质量。利用该装置，我们将量子限制线性放大器的搜索速度提高了20倍，并为用5 GHz以上的谐振探测器探测轴子的存在性设定了新的标准。2025年由美国物理学会出版
