A constructive orthogonalization method tailors quantum sensor networks to ignore chosen noise waves while retaining Heisenberg-limited sensitivity to a signal wave, with exponential advantage over product states under strong noise.
Notice that this scalar product is chosen to reproduce the eigenvalues in Eq
