The weak-value (WV) measurement proposed by Aharonov, Albert, and Vaidman (AAV) has
attracted a great deal of interest in connection with quantum metrology. In this paper, we …

Through the von Neumann interaction followed by post-selection, we can extract not only the
eigenvalue of an observable of the measured system but also the weak value. In this post …

A modified weak-value-amplification (MWVA) technique to measure a mirror's velocity based
on the Vernier effect is proposed. To demonstrate its enhanced sensitivity and higher signal …

Quantum mechanics presents peculiar properties that, on the one hand, have been the
subject of several theoretical and experimental studies about its very foundations and, on …

Lehrer-Graiwer, Kobina Dufu, Nicholas E. Vlahakis, and Bruce D. Johnson. Impact of …

The weak value, the average result of a weak measurement, has proven useful for probing
quantum and classical systems. Examples include amplifying small signals, investigating …

State preparation via postselected weak measurements in a three-wave mixing process is
studied. We assume the signal input mode is prepared in a vacuum state, coherent state, or …

By choosing more orthogonality between preselection and postselection states, one can
significantly improve the sensitivity in general optical quantum metrology based on the weak …

In this work, we study the measurement transition for a coherent squeezed pointer state
through a transition factor Γ that involves a system-pointer coupling by using an arbitrary …

Recently, the measurement transition between von Neumann's projective strong
measurement and Aharonov's weak measurement are investigated theoretically and …
