The demonstration of superadditive quantum-coding gain experiment was analyzed. A design strategy of quantum-collective decoding in physical quantum circuits was emphasized. The superadditive quantum coding became essential in the region where the noncommutativity of signal states was the main ambiguity among signals. It was stated that only quantum decoding can be the core technology to achieve the ultimate performance in future long-haul optical communications.
