Abstract The long-term free evolution of wave packets formed by highly excited states of quantum systems performing regular periodic motion in the classical limit is considered. The universal asymptotic scenario of the wave function temporal development is discovered which provides the generation of a certain sequence of initial wave packet fractional revivals. Each revival represents the coherent superposition of macroscopically distinguishable quantum states. The manifestation of the phenomenon in the dynamics of a Rydberg atom excited by a short laser pulse is discussed.
