Given a quantum observable and a state, one can construct a classical observable, such that it is the optimal estimate of the quantum observable, in the sense of minimum variance. We demonstrate how t...
Generalized shifts and weak values for polarization components of reflected light beams
Generalized shifts weak values polarization components of reflected light beams Optics

The simple reflection of a light beam of finite transverse extent from a homogenous interface gives rise to a surprisingly large number of subtle shifts and deflections which can be seen as diffractiv...
Experimental Evidence for a Dynamical Non-Locality Induced Effect in Quantum Interference Using Weak Values
Experimental Evidence Dynamical Non-Locality Induced Effect in Quantum Interference Weak Values
2010/11/5
The quantum theoretical concepts of modular momentum and dynamical non-locality, which were introduced four decades ago, have recently been used to explain single particle quantum interference phenome...

A protocol employing weak values (WVs) to obtain ultra sensitive amplification of weak signals
in the context of a solid state setup is proposed. We consider an Aharonov-Bohm interferometer
where bo...
