Robust self-testing quantum states and binary nonlocal XOR games    [PDF]

Carl Miller, Yaoyun Shi

Self-testing a quantum state means verifying the existence of a certain multipartite quantum state based only on knowledge of the probability distributions of certain measurements on the state. Self-testing is possible even when the measurement devices are untrusted. This paper is concerned with proving robust (i.e., error-tolerant) self-testing results. We devise a general scheme for proving such results for nonlocal binary XOR games. We apply this scheme to prove a result for the Greenberger-Horne-Zeilinger paradox.
