Hi all- The seminar will be on Mondays at 4:30 PM. The group meeting will be on Tuesday at either 10 AM or 11 AM. At some point, we'll might discuss bosonic channel capacity. We'll discuss state restoration next week. We should read http://arxiv.org/abs/1001.0745 to see if we're interested. Today, Philip Walther (visiting from Vienna) told us about nonlinear optics. His group tries to generate big GHZ states using nonlinear crystals that sometimes generates EPR pairs. They generate very high fidelities, but their system does not scale efficiently past about 10 photons. --Andy _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip
