AI 中文摘要
在弱测量 regime 中，后选择可导致观测到反常弱值，这看似与测量相互作用为强时观测到的本征值统计相矛盾。本文研究后选择测量中指针统计对测量强度的依赖关系，发现弱测量与强测量之间中间 regime 的指针统计几乎不依赖于测量强度，并表明在该 regime 中系统对指针执行动量测量。弱测量与强测量之间的过渡可通过系统与指针角色的反转来解释，其中后选择充当指针信息的读出。
英文摘要
In the weak measurement regime, post-selection can result in the observation of anomalous weak values, seemingly contradicting the eigenvalue statistics observed when the measurement interaction is strong. Here, we investigate the dependence of meter statistics on measurement strength in a post-selected measurement. We find that the meter statistics in the intermediate regime between weak and strong measurements is nearly independent of measurement strength and show that, in this regime, the system performs a measurement of momentum on the meter. The transition between weak and strong measurements is explained by a reversal of the roles of the system and the meter, where the post-selection acts as a readout of information about the meter.
