Beyond the Magic Square Game: Widening the Entangled-Classical Gap for Two Bell States

New nonlocal game (1/7-SAMS) widens the entangled-classical gap for two Bell states from 1/9 to 4/35, surpassing the Mermin-Peres magic square using full 2-qubit Pauli group symmetry to advance device-independent self-testing.

Quantitative Quantum Soundness for All Multipartite Compiled Games

The KLVY compiler preserves quantum soundness for multipartite nonlocal games, enabling execution of multi‑prover tests. The proof gives explicit advantage bounds. getnews.me/quantitative-quantum-sou... #quantumcryptography #nonlocalgames
