  In ``Distributed quantum sensing with mode-entangled spin-squeezed atomic
states" Nature (2022), Malia et. al. claim to improve the precision of a
network of clocks by using entanglement. In particular, by entangling a clock
network with up to four nodes, a precision 11.6 dB better than the quantum
projection noise limit (i.e. precision without any entanglement) is reported.
These claims are incorrect, Malia et. al. do not achieve an improved precision
with entanglement. Here we show their demonstration is more than two orders of
magnitude worse than the quantum projection noise limit.
