[Aspuru-Guzik group list] [qip] Special Seminar Wednesday - Renato Renner

by Shelby Kimmel

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

[Aspuru-Guzik group list] [Aspuru-meetings-list] Prof. Apoorva Patel's visit tomorrow

by Borzumehr Toloui Semnani

Hi everyone, this is a reminder that tomorrow, July 1st, Prof. Apoorva Patel is visiting the group for one day. Prof. Patel will give a talk at 3pm on the optimization of quantum Hamiltonian evolution. ------------- Title: Optimisation of Quantum Hamiltonian Evolution Speaker: Apoorva Patel Centre for High Energy Physics Indian Institute of Science, Bangalore-560012 Abstract: Given a quantum Hamiltonian and its evolution time, the corresponding unitary evolution operator can be constructed in many different ways, corresponding to different trajectories between the desired end-points. A choice among these trajectories can then be made to obtain the best computational complexity and control over errors. It is shown how a construction based on Grover's algorithm scales linearly in time and only logarithmically in error bound, and is clearly superior to the scheme based on straightforward application of the Lie-Trotter formula. --------------- You can read more about his background in his home page http://cts.iisc.ernet.in/Personnel/adpatel.html You can meet him after 11am or accompany him for lunch. If you are interested in meeting him during his visit please let me know. Cheers, Borzu Toloui

Re: [Aspuru-Guzik group list] Wiki

by Sawaya, Nicolas

Hi Friends, As was mentioned very briefly in group meeting yesterday, please let me know if you're sort of an informal "point person" for any of the software we have. The page is here: https://aspuru.wikidot.com/computation. It would be good if people know whom they should speak with, when they want a copy of or help with these packages!
