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 …

We report on the use of an interferometric weak value technique to amplify very small
transverse deflections of an optical beam. By entangling the beam's transverse degrees of …

Recently, weak measurements were used to measure small effects that are transverse to the
propagation direction of a light beam. Here we address the question of whether weak …

Measurement-driven transitions between extensive and subextensive scaling of the
entanglement entropy receive interest as they illuminate the intricate physics of …

We report repeated single-shot measurements of the two-electron spin state in a GaAs
double quantum dot. The readout allows measurement with a fidelity above 90% with a∼ 7 …

The amplification obtained using weak values is quantified through a detailed investigation
of the signal-to-noise ratio for an optical beam-deflection measurement. We show that for a …

Unlike the real part of the generalized weak value of an observable, which can in a restricted
sense be operationally interpreted as an idealized conditioned average of that observable in …

Measurement-induced phase transitions are the subject of intense current research, both
from an experimental and a theoretical perspective. We explore the concept of implementing …

Large weak values have been used to amplify the sensitivity of a linear response signal for
detecting changes in a small parameter, which has also enabled a simple method for …
