| 英文摘要 | Pre- and post-selected (pps) measurement, especially the weak pps measurement, has been proved to be a useful tool for measuring extremely tiny physical parameters. however, it is difficult to retain both the attainable highest measurement sensitivity and precision with the increase of the parameter to be measured. here, a modulated pps measurement scheme based on coupling-strength-dependent modulation is presented with the highest sensitivity and precision retained for an arbitrary coupling strength. this idea is demonstrated by comparing the modulated pps measurement scheme with the standard pps measurement scheme in the case of unbalanced input meter. by using the fisher information metric, we derive the optimal pre- and post-selected states, as well as the optimal coupling-strength-dependent modulation without any restriction on the coupling strength. we also give the specific strategy of performing the modulated pps measurement scheme, which may promote practical application of this scheme in precision metrology. |
