DOI: 10.1007/s10701-019-00245-3
Abstract: We investigate in this work the meaning of weak values through the prism of property ascription in quantum systems. Indeed, the weak measurements framework contains only ingredients of the standard quantum formalism, and as such… read more here.

DOI: 10.1007/s10701-021-00534-w
Abstract: In combination with post-selection, weak measurements can lead to surprising results known as anomalous weak values. These lie outside the bounds of the spectrum of the relevant observable, as in the canonical example of measuring… read more here.

DOI: 10.1088/1367-2630/ad9771
Abstract: Geometric phases and weak values (WVs) are two fundamental concepts that were originally introduced in the realm of quantum mechanics. In the course of time, it became clear that the two concepts apply in both… read more here.

DOI: 10.1088/1751-8121/ae1646
Abstract: Bohmian mechanics is a deterministic account of quantum phenomena in terms of particle trajectories. Guided by a quantum force, the gradient of a quantum potential, trajectories bend to account for quantum interference. The quantum potential… read more here.

DOI: 10.1098/rsta.2016.0395
Abstract: Recent controversy regarding the meaning and usefulness of weak values is reviewed. It is argued that in spite of recent statistical arguments by Ferrie and Combes, experiments with anomalous weak values provide useful amplification techniques… read more here.

DOI: 10.1103/physreva.109.022238
Abstract: Many quantum paradoxes based on a realistic view of weak values were discussed in the last decades. They lead to astonishing conclusions such as the measurement of a spin component of a spin-1/2 particle resulting… read more here.

DOI: 10.1103/physreva.97.046103
Abstract: We discuss the preceding Comment and conclude that the arguments given there against the relevance of null weak values as representing the absence of a system property are not compelling. We give an example in… read more here.

Abstract: The wave function is important for understanding and predicting the behavior of photons. Recent studies have shown that wave function can be reconstructed through weak measurement. But currently, the relationships of wave function, weak value,… read more here.

DOI: 10.1364/ol.375448
Abstract: We experimentally demonstrate an alternative method for measuring nonlocal weak values in linear optics, avoiding the use of second-order interaction. The method is based on the concept of modular values. The paths of two photons,… read more here.
