Description: This work investigates Extremal Non-Signaling (ENS) boxes, which are specific correlations at the boundary of non-signaling possibilities. The authors construct many such boxes and show that even two copies of any ENS box violate fundamental principles like local orthogonality. This demonstrates that neither quantum theory nor ideal measurements can produce nonlocal ENS boxes.
