[Aspuru-Guzik group list] watch out for your belongings

by Stéphanie Valleau

Hi everyone, Sorry for the alarming subject line, but I was just told by Mike Paterno that there was a wallet stolen on the third floor of mallinckrodt this afternoon. He said something about the suspect being a guy with red shorts and a beard. Anyways this is just a heads up .. Cheers, Stephanie

[Aspuru-Guzik group list] Discussion on measuring molecules proposal

by Dmitrij Rappoport

Dear group, Thank you again for your interest and the productive discussion yesterday. We will be working on formulating a grant proposal based on some of these ideas over the summer, so I think it would be useful to coordinate the activities. All those interested are welcome to come and to contribute to the grant proposal for the group: (i) We can have informal discussion about the proposal details next Thursday in our regular group meeting slot: Thursday, July 24, 2:30pm in the Kahne conference room (Converse 102) (ii) I started a latex document for the grant proposal on Authorea.com. Email me if you are interested to contribute and I'll send you an invitation. Thank you all, Dmitrij Dr. Dmitrij Rappoport Department of Chemistry and Chemical Biology, Harvard University 12 Oxford Street, Cambridge, MA 02138, USA phone: (617) 495 9676, mobile: (857) 600 6846 email: rappoport(a)chemistry.harvard.edu

[Aspuru-Guzik group list] [qip] Seminar :: Prof. Michael Biercuk :: Thursday, July 31st 4:30pm :: 36-428

by Paola Cappellaro

** Special Seminar ** Thursday :: July 31st :: 4:30pm :: Haus Room 36-428 (MIT) == Control in Quantum Coherent Systems == Prof. Michael Biercuk, School of Physics, University of Sidney == Abstract == Tremendous research activity worldwide has focused on attempting to harness the exotic properties of quantum physics for new applications in metrology, computation, and communications - a push to develop engineered quantum systems. Underlying any such capability is the need to exert control over a chosen quantum system in order to coax it into performing useful tasks. In this talk we describe the physics and engineering challenges faced in controlling quantum coherent systems. We introduce and validate an efficient transfer-function-based framework for predicting quantum dynamics [1] through experiments using trapped Ytterbium ions [2]. This framework reveals novel insights into the physics underlying the performance of a wide variety of NMR and quantum-information inspired control techniques. We then demonstrate how combining this new understanding of controlled quantum dynamics with functional analysis allows us to address challenging problems ranging from quantum computation and simulation [3-4] to precision frequency metrology [5].

[Aspuru-Guzik group list] Special Seminar - Friday, July 25, 2PM, RM 3-333

by Catherine M Bourgeois

Dear Colleagues: Prof. Carmel Rotschild from Technion - Israel Institute of Technology will be visiting our department this Friday, July 25, and will deliver a lecture at 2PM in Rm 3-333. Lecture Title & Abstract: Thermally Enhanced Photoluminescence for Efficient Photovoltaics, Assaf Manor1, Leopoldo L. Martin2 and Carmel Rotschild1,2 1 Russell Berrie Nanotechnology Institute, Technion − Israel Institute of Technology, Haifa 32000, Israel, 2 Department of Mechanical Engineering, Technion − Israel Institute of Technology, Haifa 32000, Israel Email: carmelr@.technion.ac.il<mailto:carmelr@.technion.ac.il> The Shockley-Queisser (SQ) efficiency limit for single-junction solar-cells is to a great extent due to inherent heat dissipation accompanying the quantum process of electro-chemical potential generation. Concepts such as solar thermo-photovoltaics (STPV) and thermo-photonics aim to harness this dissipated heat, yet exceeding the SQ limit has not been achieved due to high operating temperatures. Here we experimentally demonstrate the generalized Planck's law for endothermic-photoluminescence (PL) at high temperatures, and the inherent abrupt transition from PL to thermal emission. We also show how endothermic PL generates orders of magnitude more energetic photons than thermal emission at similar temperatures. Relying on these observations, we propose and theoretically study a highly efficient solar-energy converter, wherein solar radiation is absorbed by a low-bandgap PL material. The dissipated heat is emitted by endothermic PL, and harvested by a higher-bandgap photovoltaic cell. While such device operates at much lower temperatures than STPV, the theoretical efficiencies approaches 70%, bringing its realization into reach. Speaker Biography: Carmel got his PhD from the Physics Department at Technion in 2008. He was subsequently a postdoc with Prof. Marc Baldo at MIT before joining the faculty of the Mechanical Engineering Department at Technion. You can read more on his research here: http://meeng.technion.ac.il/Carmel_Rotschild.htm<https://mailtrack.io/trace/link/25d5d2be136423a184ee3890ae25be0ee038a904> I hope to see you at his seminar on Friday. Best wishes, Svetlana Boriskina Professor of Electrical Engineering and Computer Science Director of the Center for Excitonics Associate Director, Research Laboratory of Electronics MIT, Room 13-3053 77 Massachusetts Av, Cambridge, MA 02139 baldo(a)mit.edu<mailto:baldo@mit.edu> http://softsemi.mit.edu/ http://www.rle.mit.edu/excitonics/

[Aspuru-Guzik group list] [qip] today and tomorrow and Friday

by Edward Farhi

Hi Quanta Today at 1:30 we have David Gross giving a talk in 6-310. Title: Low-rank methods: From single pixel cameras to quantum state tomography Abstract: Every time the release button of a digital camera is pressed, several megabytes of raw data are recorded. But the size of a typical jpeg output file is only 10% of that. What a waste! Can't we design a process which records only the relevant 10% of the data to begin with? The theory of compressed sensing achieves this trick for sparse signals. A basis-independent notion of "sparsity" for a matrix is its rank. One is thus naturally led to the "low-rank matrix recovery" problem: can one reconstruct an unknown low-rank matrix from few linear measurements? Applications can be found in areas as diverse as face recognition, the analysis of x-ray diffraction images, and quantum state estimation. I will give an introduction to this field and emphasize how methods originally developed in quantum physics proved well-suited to the theory. Tomorrow Umesh is speaking at Microsoft Research. I believe it is at 3:00. On Friday we will have our group meeting at 11:00 and Jeongwan will tell us about what he has been doing. Best, Eddie *********************************************** Edward Farhi Cecil and Ida Green Professor of Physics Director Center for Theoretical Physics Massachusetts Institute of Technology 6-300 Cambridge MA 02139 617 253 4871 *********************************************** _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

Re: [Aspuru-Guzik group list] XSEDE allocations for Harvard University

by Alan Aspuru-Guzik

Dear Bob, It is funny as I was just encouraging our group members to use XSEDE. We are having a meeting with RC this Thursday to discuss computing. I think it would be great if you could come in and talk to us. (Us is a royal "us" as I will be away for 3 weeks). I can meet you after that. I copy my group members, and specifically Suleyman Er, who is my local XSEDE appointee. Our cluster usage in Oddyssey is quite subscribed recently and people are going to start using XSEDE more. I am glad we have you on campus to help the group members with issues on XSEDE. Martin Blood-Forsythe will e-mail you the location and details of the meeting Alan Alán Aspuru-Guzik | Professor of Chemistry and Chemical Biology Harvard University | 12 Oxford Street, Room M113 | Cambridge, MA 02138 (617)-384-8188 | http://aspuru.chem.harvard.edu | http://about.me/aspuru On Mon, Jul 21, 2014 at 12:00 PM, Bob Freeman <robertfreeman(a)g.harvard.edu> wrote: > Alan, > > I'm writing as a courtesy to introduce myself as the Harvard University > (main campus) Campus Champion for XSEDE.
