  The uncertainty principle sets lower bound on the uncertainties of two
incompatible observables measured on a particle. The uncertainty lower bound
can be reduced by considering a particle as a quantum memory entangled with the
measured particle. In this paper, we consider a tripartite scenario in which a
quantum state has been shared between Alice, Bob, and Charlie. The aim of Bob
and Charlie is to minimize Charlie's lower bound about Alice's measurement
outcomes. To this aim, they concentrate their correlation with Alice in
Charlie's side via a cooperative strategy based on local operations and
classical communication. We obtain lower bound for Charlie's uncertainty about
Alice's measurement outcomes after concentrating information and compare it
with the lower bound without concentrating information in some examples. We
also provide a physical interpretation of the entropic uncertainty lower bound
based on the dense coding capacity.
