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).
