Colloquium: Understanding quantum weak values: Basics and applications

J Dressel, M Malik, FM Miatto, AN Jordan… - Reviews of Modern Physics, 2014 - APS
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 …

Nonperturbative theory of weak pre-and post-selected measurements

AG Kofman, S Ashhab, F Nori - Physics Reports, 2012 - Elsevier
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 …

Negative quasiprobabilities enhance phase estimation in quantum-optics experiment

N Lupu-Gladstein, YB Yilmaz… - Physical Review Letters, 2022 - APS
Operator noncommutation, a hallmark of quantum theory, limits measurement precision,
according to uncertainty principles. Wielded correctly, though, noncommutation can boost …

Technical advantages for weak-value amplification: when less is more

AN Jordan, J Martínez-Rincón, JC Howell - Physical Review X, 2014 - APS
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 …

Phase estimation with weak measurement using a white light source

XY Xu, Y Kedem, K Sun, L Vaidman, CF Li, GC Guo - Physical review letters, 2013 - APS
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 …

Quantum advantage in postselected metrology

DRM Arvidsson-Shukur, N Yunger Halpern… - Nature …, 2020 - nature.com
In every parameter-estimation experiment, the final measurement or the postprocessing
incurs a cost. Postselection can improve the rate of Fisher information (the average …

Weak-values technique for velocity measurements

GI Viza, J Martínez-Rincón, GA Howland, H Frostig… - Optics letters, 2013 - opg.optica.org
In a recent Letter, Brunner and Simon proposed an interferometric scheme using imaginary
weak values with a frequency-domain analysis to outperform standard interferometry in …

Weak value amplification can outperform conventional measurement in the presence of detector saturation

J Harris, RW Boyd, JS Lundeen - Physical review letters, 2017 - APS
Weak value amplification (WVA) is a technique by which one can magnify the apparent
strength of a measurement signal. Some have claimed that WVA can outperform more …

Significance of the imaginary part of the weak value

J Dressel, AN Jordan - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
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 …

Tests of fundamental quantum mechanics and dark interactions with low-energy neutrons

S Sponar, RIP Sedmik, M Pitschmann, H Abele… - Nature Reviews …, 2021 - nature.com
Among the known particles, the neutron is special because it provides experimental access
to all of the four fundamental forces and a wide range of hypothetical interactions. Despite …
