Our paper, Classical analog for dispersion cancellation of entangled photons with local detection, was published online today in Physical Review A.
Abstract: Energy-time entangled photon pairs remain tightly correlated in time when the photons are passed through equal magnitude, but opposite in sign, dispersion.Arecent experimental demonstration has observed this effect on ultrafast time scales using second-harmonic generation of the photon pairs. However, the experimental signature of this effect does not require energy-time entanglement. Here, we demonstrate a direct analogue to this effect in narrow-band second-harmonic generation of a pair of classical laser pulses under similar conditions. Perfect cancellation is observed for fs pulses with dispersion as large as 850 fs^2, comparable to the quantum result, but with an 10^13-fold improvement in signal brightness.
