资源简介：
We propose a quick-test method for the two-photon spectral correlation quantification based
on a dual-channel filter and a dispersive element, where the spectral correlation coefficient
can be readily evaluated from directly measurable parameters in a coincidence measurement.
Verified experiments have been conducted on two biphoton sources with different types of
spectral correlation, presenting nice agreement with the joint spectrum measurement. Because
of its simple implementation and fast measurement within seconds, this scheme is promising to
be a plug-and-play tool for spectral correlation quantification, which would facilitate various
quantum information applications with on-demand spectral correlation.
