Classical capacity of a noiseless quantum channel assisted by noisy entanglement
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki +2
We derive the general formula for the capacity of a noiseless quantum channel assisted by an arbitrary amount of noisy entanglement. In this capacity formula, the ratio of the quan…
