Implications of superstrong non-locality for cryptography
Implications of superstrong non-locality for cryptography
Non-local boxes are hypothetical āmachinesā that give rise to superstrong non-local correlations, leading to a stronger violation of Bell/Clauser, Horne, Shimony & Holt inequalities than is possible within the framework of quantum mechanics. We show how non-local boxes can be used to perform any two-party secure computation. We first construct ā¦
