“Nonlocal” dispersion cancellation with classical light

In this work, we consider nonlocal dispersion cancellation with classical light in a setup. We demonstrate that the dispersion cancellation phenomenon of temporally entangled two-photon states of light in continuous-wave (CW) pumped SPDC can be similarly obtained in intensity interferometry with classical, stationary radiation that obeys Gaussian statistics. Specifically, we show that the correlation of the intensity fluctuations that would be measured in a setup plays the role of the temporally resolved intensity coincidence detection measured (a) (the original setup for the dispersion cancellation). The only difference is a different dispersion compensation rules which comes from the fact that CW-pumped SPDC photons are anticorrelated in frequency, whereas stationary light has, by definition, uncorrelated spectrum.
