- Abstract: We show how quantum correlations allow us to break the local speed limits of
physical processes using only local measurements and classical communication
between two parties that share an entangled state. Inequalities that bound the
minimal time of evolution of a quantum state by energy fluctuations can be
violated in the presence of steering by conditioning on the measurement
outcomes of a remote system. Our results open up new pathways for studying how
quantum correlations influence the dynamical properties of states and
observables.
