Quantum-coherence-free precision metrology by means of difference-signal amplification
Jialin Li, Yazhi Niu, Xinyi Wang +2
The novel weak-value-amplification (WVA) scheme of precision metrology is deeply rooted in the quantum nature of destructive interference between the pre- and post-selection states…

Quality analysis for precision metrology based on joint weak measurements without discarding readout data
Lupei Qin, Luting Xu, Xin-Qi Li
We present a theoretical analysis for the metrology quality of joint weak measurements (JWM), in close comparison with the weak-value-amplification (WVA) technique. We point out th…

Fisher information analysis on post-selection involved quantum precision measurements using optical coherent states
Yingxin Liu, Lupei Qin, Xin-Qi Li
The weak-value-amplification (WVA) technique has been extensively considered and debated in the field of quantum precision measurement, largely owing to the reduced Fisher informat…
