Since its introduction 25 years ago, the quantum weak value has gradually transitioned from
a theoretical curiosity to a practical laboratory tool. While its utility is apparent in the recent …

This paper starts with a brief review of the topic of strong and weak pre-and post-selected
(PPS) quantum measurements, as well as weak values, and afterwards presents original …

The technical merits of weak-value-amplification techniques are analyzed. We consider
models of several different types of technical noise in an optical context and show that weak …

We report results of a high precision phase estimation based on a weak measurement
scheme using a commercial light-emitting diode. The method is based on a measurement of …

In standard quantum weak measurements, preselection and postselection of quantum states
are implemented in the same photon. Here we go beyond this restrictive setting and …

We theorize the spin Hall effect of light (SHEL) on a nanometal film and demonstrate it
experimentally via weak measurements. A general propagation model to describe the …

We present a weak measurement protocol that permits a sensitive estimation of angular
rotations based on the concept of weak-value amplification. The shift in the state of a pointer …

In every parameter-estimation experiment, the final measurement or the postprocessing
incurs a cost. Postselection can improve the rate of Fisher information (the average …

We show that weak measurement can be used to “amplify” optical nonlinearities at the
single-photon level, such that the effect of one properly postselected photon on a classical …

This article presents a general discussion of several aspects of our present understanding of
quantum mechanics. The emphasis is put on the very special correlations that this theory …
