The possibility of absolute calibration of analog detectors by using parametric down-conversion: a systematical study
Giorgio Brida, Maria Chekhova, Marco Genovese +2
Accurate calibration of photodetectors both in analog and in photon-counting regime is fundamental for various scientific applications, which range from "traditional" quantum optic…
Generalized quantum measurements. Part I: Information properties of soft quantum measurements
Boris A. Grishanin, Victor N. Zadkov
A special class of soft quantum measurements as a physical model of the fuzzy measurements widely used in physics is introduced and its information properties are studied in detail…
Chaotic Tunneling in a Laser Field
V. L. Golo, Yu. S. Volkov
We study the driven tunneling of a one-dimensional charged particle confined to a rectangular double-well. The numerical simulation of the Schrödinger equation based on the Cranck-…
Hamilton-Jacobi-Bellman equations for Quantum Filtering and Control
J. Gough, V. P. Belavkin, O. G. Smolyanov
We exploit the separation of the filtering and control aspects of quantum feedback control to consider the optimal control as a classical stochastic problem on the space of quantum…
Geometric phase around exceptional points
A. A. Mailybaev, O. N. Kirillov, A. P. Seyranian
A wave function picks up, in addition to the dynamic phase, the geometric (Berry) phase when traversing adiabatically a closed cycle in parameter space. We develop a general multid…
