Unitaries have an exactly quantifiable purity-constrained imaginarity-generating power that depends on intrinsic unitary properties and concentrates near its maximum for typical Haar-random dynamics in high dimensions.
Framework deriving hierarchies of Wigner negativity witnesses from L_p-norm, log-convexity, and Hankel-matrix constraints on moments, plus multicopy parity observables for estimation from few copies, demonstrated via simulations and extended to entanglement.

Strong nonlocality with more imaginarity and less entanglement
Five orthogonal three-qubit states exhibit strong nonlocality if and only if they contain imaginary components, forming the smallest unextendible biseparable basis of cardinality d² + d - 1 while spanning a locally indistinguishable subspace whose complement yields distillable genuine entanglement.
