When two players achieve a superclassical score at a nonlocal game, their outputs must contain intrinsic randomness. This fact has many useful implications for quantum cryptography. Recently it has been observed (C. Miller, Y. Shi, Quant. Inf. & Comp. 17, pp. 0595-0610, 2017) that such scores also imply the existence of local randomness - that is, randomness known to one player but not to the other. This has potential implications for cryptographic tasks between two cooperating but mistrustful… Expand
