Super-additivity in communication of classical information through quantum channels from a quantum parameter estimation perspective
We point out a contrasting role the entanglement plays in communication and estimation scenarios. In the first case it brings noticeable benefits at the measurement stage (output super-additivity), whereas in the latter it is the entanglement of the input probes that enables significant performance...
