  We experimentally demonstrate the achievement of the entanglement assisted
capacity for classical information transmission over a depolarizing channel.
The implementation is based on the generation and local manipulation of 2-qubit
Bell states, which are finally measured at the receiver by a complete Bell
state analysis. The depolarizing channel is realized by introducing quantum
noise in a controlled way on one of the two qubits. This work demonstrates the
achievement of the maximum allowed amount of information that can be shared in
the presence of noise and the highest reported value in the noiseless case.
