Introduction to Weak Measurements and Weak Values

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… Expand

Geometric phase from Aharonov–Bohm to Pancharatnam–Berry and beyond

- E. Cohen, H. Larocque, F. Bouchard, Farshad Nejadsattari, Y. Gefen, E. Karimi
- PhysicsNature Reviews Physics
- 1 July 2019

Whenever a quantum system undergoes a cycle governed by a slow change of parameters, it acquires a phase factor: the geometric phase. Its most common formulations are known as the Aharonov-Bohm,… Expand

Measurement and collapse within the two-state vector formalism

- Y. Aharonov, E. Cohen, Eyal Gruss, Tomer Landsberger
- Economics
- 24 June 2014

The notion of collapse is discussed and refined within the two-state vector formalism (TSVF). We show how a definite result of a measurement can be fully determined when considering specific forward-… Expand

Probing finite coarse-grained virtual Feynman histories with sequential weak values

- Danko D. Georgiev, E. Cohen
- Physics
- 25 September 2017

Feynman's sum-over-histories formulation of quantum mechanics has been considered a useful calculational tool in which virtual Feynman histories entering into a quantum superposition cannot be… Expand

Determining the quantum expectation value by measuring a single photon

- F. Piacentini, A. Avella,
+9 authors M. Genovese - Physics
- 27 June 2017

A photonic experiment demonstrates protective measurements, a type of weak measurements. These make it possible to determine the expectation value of the polarization of a photon from a single… Expand
