Talk by Johan Aaberg
by Stefan Wolf 08 Nov '10

08 Nov '10

Hi, This week's seminar talk will be given by Johan Aaberg: Tuesday, Nov. 9, 17:00 in CAB H 53 at Zentrum. Best regards, Stefan _______________________________________________________________ Title: Yet another work extraction Abstract: In lack of better ideas I am going to torment you with another of those "work extraction" and "erasure" problems. This investigation provides a small step towards understanding single-shot erasure and work extraction in systems with non-trivial Hamiltonians. I have to admit that this is going to be somewhat physics flavored, but I will try to keep myself in check. In any case, the pain will be very brief; I will only present the model and the main results. _______________________________________________________________

James Wootton: QSIT Seminar on Monday, Nov 8, 2010
by Ilona Blatter 05 Nov '10

05 Nov '10

Dear all Please be informed about the following QSIT Seminar. With best regards, Ilona Blatter ------------------------------------------------------------------------------------------------------ Date: Monday November 8, 2010 Time: 41:00 Place: HIT H 42 Host: Atac Imamoglu Bringing order through disorder: Localization in the toric code James Wootton University of Leeds, UK Anderson localization emerges in quantum systems when randomised parameters cause the exponential suppression of motion. In this talk we will consider the localisation phenomenon in the toric code and its ability to sustain quantum information in a fault tolerant way. First we will show that, in the presence of a magnetic field, the existence of a single anyon pair destroys logical information in a time linear with the system size. However, once the disorder, inherent in any physical realisation of the code, is taken into account, it allows the tolerable density of anyons to remain finite as the localisation effect takes place. Enhancements to this effect are also considered using random lattices. ------------------------------------------------------------------------------------------------------ ETH Zurich Dr. Ilona Blatter QSIT Coordinator Laboratory for Solid State Physics HPF E 13 Schafmattstrasse 16 8093 Zurich ilona.blatter(a)phys.ethz.ch www.qsit.ethz.ch Phone: +41 44 633 36 06 Home: +41 44 844 42 50
