quantum.halowerk.com/v1/portfolio-qaoa

Enumerates every selection of exactly k assets for at most 16 assets, maximizing summed expected return minus a caller-selected covariance penalty. It runs no quantum circuit and provides a deterministic classical optimum for testing a corresponding binary QAOA or QUBO formulation; it is not investment advice and ignores transaction costs and allocation sizes.
