Introduction to Weak Measurements and Weak Values
Quanta, 2013 We present a short review of the theory of weak measurement. This should serve as a map for the theory and an easy way to get familiar with the main results, problems and paradoxes raised by the theory. Quanta 2013; 2: 7–17.

Triaxial closed-loop measurement based on a single-beam zero-field optically pumped magnetometer
Frontiers in Physics, 2022 In this study, we propose an approach for the simultaneous measurement of triaxial magnetic fields using a single-beam zero-field optically pumped atomic magnetometer, in which a rotational high-frequency (ω1) and another high-frequency (ω2) modulated ...

Demystifying Weak Measurements [PDF]
Foundations of Physics, 2017 A large literature has grown up around the proposed use of 'weak measurements' (i.e., unsharp measurements followed by post-selection) to allegedly provide information about hidden ontological features of quantum systems. This paper attempts to clarify the fact that 'weak measurements' involve strong (projective) measurements on one (pointer) member of

Quantum weak-interaction-based measurement: from sequential weak measurement to protective measurement [PDF]
Quantum Communications and Quantum Imaging XVI, 2018 Weak value measurements have been a real breakthrough in the quantum measurement framework. In particular, quantum measurements may take advantage by anomalous weak values, i.e. values out of the eigenvalues spectrum of the measured observable, both for implementing new measurement techniques and studying Quantum Mechanics foundations.

Results in Physics, 2023 In this paper, we propose a three-axis atomic magnetometer (AM), in which one light beam is divided into two orthogonal spatially separated pump beams by a lateral displacement polarized beam splitter and reflector mirrors; this scheme suppresses the ...

Compact optical pumping system based on offaxis freeform mirror collimation for miniaturized atomic gyroscopes [PDF]
EPJ Web of ConferencesConventional optical systems for laser beam expansion, collimation, and reflective path configurations in miniaturized atomic gyroscopes face challenges due to excessive volume and component complexity, limiting further optical integration.

Weak values in continuous weak measurements of qubits
Physical Review A, 2015 For continuous weak measurement of qubits, we obtain exact expressions for weak values (WVs) from the post-selection restricted average of measurement outputs, by using both the quantumtrajectory- equation (QTE) and quantum Bayesian approach. The former is applicable to short-time weak measurement, while the latter can relax the measurement strength to

Weak measurement of the Goos–Hänchen shift [PDF]
Optics Letters, 2013 It is well known from quantum mechanics that weak measurements offer a means of amplifying and detecting very small phenomena. We present here the first experimental observation of the Goos-Hanchen shift via a weak measurement approach.
