Hi Everyone, This week we have a special quantum information seminar given by Renato Renner. He will be speaking Wednesday April 2 at 4:30 (note time change from standard seminar!) in room 6C-442. Title and and abstract are below. Hope to see you there. Best, Shelby Title: Reliable Quantum State Tomography Abstract: Quantum state tomography is the task of estimating the state of a quantum system using measurements. Typically, one is interested in the (unknown) state generated during an experiment which can be repeated arbitrarily often in principle. However, the number of actual runs of the experiment, from which data is collected, is always finite (and often small). As pointed out recently, this may lead to unjustified (or even wrong) claims when employing standard statistical tools without care. In this talk, I will present a method for obtaining reliable estimates from finite tomographic data. Specifically, the method allows the derivation of confidence regions, i.e., subsets of the state space in which the unknown state is contained with probability almost one. This is joint work with Matthias Christandl, see also arXiv:1108.5329. -- Shelby Kimmel PhD Candidate in Physics Massachusetts Institute of Technology www.mit.edu/~skimmel _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip
