Describing squeezed-light experiments without squeezed-light states
Tamíris R. Calixto, Pablo L. Saldanha
Coherent states are normally used to describe the state of a laser field in experiments that generate and detect squeezed states of light. Nevertheless, since the laser field absol…
Aharonov-Casher and shielded Aharonov-Bohm effects with a quantum electromagnetic field
Pablo L. Saldanha
We use a covariant formalism that is capable of describing the electric and magnetic versions of the Aharonov-Bohm effect, as well as the Aharonov-Casher effect, through local inte…
Interferometric sensing of the tilt angle of a Gaussian beam
S. P. Walborn, G. H. Aguilar, P. L. Saldanha +2
We investigate interferometric techniques to estimate the deflection angle of an optical beam and compare them to the direct detection of the beam deflection. We show that quantum…
Robust interferometric sensing using two-photon interference
G. H. Aguilar, R. S. Piera, P. L. Saldanha +2
Precise measurement of the angular deviation of an object is a common task in science and technology. Many methods use light for this purpose. Some of these exploit interference ef…
