论文摘要
磁性测量可以由各种传感器（例如鱿鱼和巨型磁力力）执行。该设备可以达到高精度，同时失去效率和便利性。禽类中的生物磁传感模型提出了对果态上外场的根本对响应，从而调节动物行为。受生物系统中的自由基对系统的启发，在这种简化的自由基对模型中研究了根部内耦合和初始条件的效果，因为在计量学中研究了纠缠和叠加的量子优势。为了确定自由基对之间的合作的感应益处，考虑了种间耦合。我们发现自由基的耦合决定了感应状态，而耦合的激进对系统则可以通过更宽敞的操作，从而通过更宽敞的操作来为系统提供更广泛的磁传感，从而为磁传感提供了一种更加通用和灵活的方式。
Magnetic measurement can be performed by various sensors, such as SQUID and Giant Magnetoresistance. This device can achieve high accuracy while losing efficiency and convenience. The model of biological magnetic sensing in avian proposes a radical pair response to the external field on the FLY results in regulating animal behaviour. Inspired by the radical pair system found in biological system, the effect of intra-radical coupling and the initial condition is studied in this simplified radical pair model as the quantum advantage results from entanglement and superposition are investigated in metrology. To identify the sensing benefit from the cooperation between the radical pairs, the inter-radical coupling is considered. We find the intra-radical coupling determines the sensing regime while the coupled radical pair system enables a new sensing scheme that provides a more general and flexible way for magnetic sensing in a broader range through a easier manipulation to the system.
