  The uncertainty principle brings out intrinsic quantum bounds on the
precision of measuring non-commuting observables. Statistical outcomes in the
measurement of incompatible observables reveal a trade-off on the sum of
corresponding entropies. Massen-Uffink entropic uncertainty relation (Phys.
Rev. Lett. 60, 1103 (1988)) constrains the sum of entropies associated with
incompatible measurements. The entropic uncertainty principle in the presence
of quantum memory (Nature Phys. 6, 659 (2010)) brought about a fascinating
twist by showing that quantum side information, enabled due to entanglement,
helps in beating the uncertainty of non-commuting observables. Here we explore
the interplay between temporal correlations and uncertainty. We show that with
the assistance of a prior quantum temporal information achieved by sequential
observations on the same quantum system at different times, the uncertainty
bound on entropies gets reduced.
