Spatial-Dispersion Cancellation in Quantum Interferometry
D.S. Simon, A.V. Sergienko
TL;DR
This paper explores how spatial aberrations can be canceled in quantum interferometry using type-II parametric down conversion, revealing conditions for effective cancellation and potential for simultaneous correction of multiple aberration types.
Contribution
It provides a detailed analysis of the physical mechanism behind spatial aberration cancellation and identifies specific conditions for optimal cancellation in quantum interferometry.
Findings
Aberration cancels only when the object is in a specific plane.
Simultaneous cancellation of even- and odd-order aberrations is possible in a special setup.
The physical mechanism of cancellation is thoroughly analyzed.
Abstract
We investigate cancellation of spatial aberrations induced by an object placed in a quantum coincidence interferometer with type-II parametric down conversion as a light source. We analyze in detail the physical mechanism by which the cancellation occurs, and show that the aberration cancels only when the object resides in one particular plane within the apparatus. In addition, we show that for a special case of the apparatus it is possible to produce simultaneous cancellation of both even-order and odd-order aberrations in this plane.
