Abstract

A direct solution to the management of distinguishing information in experiments involving multiple pairs of photons is presented. By adjusting parameters such as crystal length, crystal material, and the bandwidth and center wavelength of the pump, a down-conversion crystal in which the signal and idler are completely uncorrelated in frequency can be configured. With this scheme, steps may be taken to minimize frequency correlations, even when experimental constraints do not permit them to be eliminated entirely.
