Averaging quantum correlations over mutually unbiased bases, all orthonormal bases, operator bases, and unitary twirling via metric-adjusted skew information yields one intrinsic closed expression, enabling complementarity relations among wave-particle features, entropy, and average correlation.
The paper defines a geometric deficiency measure relative to maximal resource states and claims it exactly quantifies the operational disadvantage in subchannel discrimination.
Presents optimization framework and closed-form solutions for convex approximation of quantum channels under α-affinity metric for SU(2)-covariant, Pauli, and amplitude-damping cases.
