Transfer of Fisher Information in Quantum Postselection Metrology
Zi-Rui Zhong, Xia-Lin Su, Xiang-Ming Hu +4
Postselected weak measurement has shown significant potential for detecting small physical effects due to its unique weak-value-amplification phenomenon. Previous works suggest tha…

Entanglement-assist cyclic weak-value-amplification metrology
Zi-Rui Zhong, Xia-lin Su, Xiang-Ming Hu +1
Weak measurement has garnered widespread interest for its ability to amplify small physical effects at the cost of low detection probabilities. Previous entanglement and recycling…

Polarization-based cyclic weak value metrology for angular velocity measurement
Zi-Rui Zhong, Yue Chen, Wei-Jun Tan +2
Weak measurement has been proven to amplify the detection of changes in meters while discarding most photons due to the low probability of post-selection. Previous power-recycling…
