Hi all,

next week, we have a talk by Carl Miller on Wednesday (note unusual day) at 4pm in the Time Room.

Best wishes,

Title: Optimal quantum self-tests based on binary nonlocal XOR games
Speaker: Carl Miller (University of Michigan)

Abstract:
Self-testing a multipartite quantum state means verifying the existence of the state based on the outcomes of unknown or untrusted measurements. This concept is important in device-independent quantum cryptography. There are some previously known results on self-testing which involve nonlocal binary XOR games such as the CHSH test and the GHZ paradox.  In our work we expand on these results.  We provide a general criterion which, when satisfied, guarantees that a given nonlocal binary XOR game is a robust self-test.  The error term in this result is quadratic, which is the best possible.  In my talk I will explain the conceptual basis for the criterion and offer some examples.  This is joint work with Yaoyun Shi (arXiv:1207.1819).
