Pre- and post-selected measurements with coupling-strength-dependent modulation
Zhaoxue Li, Jiangdong Qiu, Xiaodong Qiu +7
Pre- and post-selected (PPS) measurement, especially the weak PPS measurement, is a useful protocol for amplifying small physical parameters. However, it is difficult to retain bot…
