Time derivatives of weak values [PDF]

open access: yesScientific Reports
The time derivative of a physical property often gives rise to another meaningful property. Since weak values provide empirical insights that cannot be derived from expectation values, this paper explores what physical properties can be obtained from the

What weak measurements and weak values really mean - Reply to Kastner [PDF]

open access: yesFoundations of Physics, 2017
Despite their important applications in metrology and in spite of numerous experimental demonstrations, weak measurements are still confusing for part of the community. This sometimes leads to unjustified criticism.

Strange Weak Values [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2010
We develop a formal theory of the weak values with emphasis on the consistency conditions and a probabilistic interpretation in the counter-factual processes.

Weak Values with Decoherence [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2009
The weak value of an observable is experimentally accessible by weak measurements as theoretically analyzed by Aharonov et al. and recently experimentally demonstrated.

Modular values and weak values of quantum observables [PDF]

open access: yesPhysical Review Letters, 2010
The concept of a modular value of an observable of a pre- and post-selected quantum system is introduced. It is similar in form and in some cases has a close connection to the weak value of an observable, but instead of describing an effective ...

Introduction to Weak Measurements and Weak Values

open access: yesQuanta, 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.

Reconstructing weak values without weak measurements [PDF]

open access: yesPhysics Letters A, 2007
I propose a scheme for reconstructing the weak value of an observable without the need for weak measurements. The post-selection in weak measurements is replaced by an initial projector measurement.

Compressive Wavefront Sensing with Weak Values [PDF]

open access: yesOptics Express, 2014
We demonstrate a wavefront sensor based on the compressive sensing, single-pixel camera. Using a high-resolution spatial light modulator (SLM) as a variable waveplate, we weakly couple an optical field's transverse-position and polarization degrees of ...

Aharonov–Bohm effect with an effective complex-valued vector potential

open access: yesNew Journal of Physics, 2023
The interaction between a quantum charge and a dynamic source of a magnetic field is considered in the Aharonov–Bohm (AB) scenario. It is shown that, in weak interactions with a post-selection of the source, the effective vector potential is, generally ...

Evidence of Predictive Power and Experimental Relevance of Weak-Values Theory

open access: yesQuantum Reports, 2021
The concepts of Weak Values (WV) and Two-State Vector Formalism (TSVF) appear to motivate new experiments and to offer novel insights into dynamical processes in various materials of several scientific and technological fields. To support this view, here
