A mixed-dimensional quantum MacWilliams identity is established relating Shor-Laflamme and unitary weight enumerators, yielding generalized Hamming, Singleton, and Scott bounds plus constraints on AME states.
Since the conditions are satisfied, any hypothetical AME state must obey the inequality in Eq
