Aram Harrow talk with abstract
by Fernando Brandao 29 Jun '12

29 Jun '12

Hi Guys, here it is the title and abstract of Aram Harrow talk on 29 June, this Friday, at 11am in HIT E 41.1. Best, Fernando Title: Separable states and their applications in computer science Abstract: I'll discuss how optimizing over separable states (or equivalently, estimating whether a density matrix is separable or entangled) is comparable in difficulty to many important approximation problems in classical computer science, such as estimating the 2->4 norm of a matrix, or estimating the minimum expansion of small subsets of a graph. These connections yield new (classical) algorithms and lower bounds for these approximation problems, and may also yield new classes of interesting quantum states by adapting results from classical computer science. Joint work with Boaz Barak, Fernando Brandao, Jon Kelner, David Steurer and Yuan Zhou (STOC 2012, arXiv:1205.4484). ___________________________

Fwd: Group Hike Revealed!
by Lidia del Rio 19 Jun '12

19 Jun '12

Sorry for those of you receiving this twice: take it as a friendly reminder to sign up in the doodle <http://www.doodle.com/y62nm8p8und3mxcd#table>. Apparently students had been left out in the first email. One day I will master all the QIT mailing lists! -------- Original Message -------- Subject: Group Hike Revealed! Date: Mon, 18 Jun 2012 10:22:22 +0200 From: Lidia del Rio <delrio(a)phys.ethz.ch> Reply-To: Quantum Information Theory <itp-qit(a)lists.phys.ethz.ch> To: <itp-qit(a)lists.phys.ethz.ch> Dear quantum walkers, You know you have been waiting for it. You heard rumors, had suspicions, discussed theories, maybe joined the underground movement to try to uncover the truth (TUMTTTUTT). Lose your sleep no longer! Here is the plan for this year's group hike. There will be two days of activities. You can join either or both. *Saturday, 11th of August: Water* Rafting in the Inn, near Scuol http://www.myswitzerland.com/en/meetings/meeting-schedule/activities-mice/a… I will choose a particular trip/activity/adventure once I know how many people are coming, but I had in mind something like this: http://www.engadin-adventure.ch/index.php/en/afternoon-trips Note that this activity will only take 3h max, meaning: 1) we can leave Zurich relatively late in the morning (around 10) 2) you can come along even if you (or your baby) aren't fond of rafting; the rest of the day will be spent enjoying the Engadine valley. There is also a rope course nearby, if you (or your children) prefer air to water: http://www.seilpark-engadin.ch/index.php/home The night will be spent near an undisclosed lovely place in Graubünden. *Sunday, 12th of August: Land* A seven-hour hike through the National Park, starting from Zernez (2:30h away from Zurich). In principle we will take this route, http://www.wanderland.ch/en/routen_etappen.cfm?subcat=RegionalRoute&id=3174… in the reverse direction. It is composed of these two routes: http://www.nationalpark.ch/go/en/visit/trails-routes/?trail=8 http://www.nationalpark.ch/go/en/visit/trails-routes/?trail=8 National park: http://www.nationalpark.ch/go/en/ We return to Zurich on Sunday evening. Please sign up *this week* here: http://www.doodle.com/y62nm8p8und3mxcd If you are signing up for Saturday, let me know what kind of activity you prefer. More details to follow soon! Best, Lidia
