Enumerates every selection of exactly k assets for at most 16 assets, maximizing summed expected return minus a caller-selected covariance penalty.

Converts ++, +−, −+ and −− counts into a correlation for each of AB, AB′, A′B and A′B′, then computes S = E(AB) + E(AB′) + E(A′B) − E(A′B′). A value above the classical bound in supplied data does not by itself demonstrate entanglement or close detection, locality, sampling or significance loopholes.

It neither exchanges quantum states nor creates a secret key: all submitted bits are disclosed to this service and must never be used as production key material.
