A quantum dispersion canceller is proposed that uses all-optical quantum signal processing based on strong quantum correlations in the signal and idler waves amplified by an optical parametric amplifier at the receiver end. It cancels the even-order dispersion and can regenerate an optical data packet without any ambiguity.
