Ahlswede R, Lober P. Quantum data processing. In: IEEE Transactions on Information Theory. IEEE TRANSACTIONS ON INFORMATION THEORY. Vol 47. IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC; 2001: 474-478.We prove a data processing inequality for quantum communication channels, which states that processing a received quantum state may never increase the mutual information between input and output states
