Bounds and optimisation of orbital angular momentum bandwidths within parametric down-conversion systems

Quantum Physics 2015-06-03 v2

Abstract

The measurement of high-dimensional entangled states of orbital angular momentum prepared by spontaneous parametric down-conversion can be considered in two separate stages: a generation stage and a detection stage. Given a certain number of generated modes, the number of measured modes is determined by the measurement apparatus. We derive a simple relationship between the generation and detection parameters and the number of measured entangled modes.
