[Aspuru-Guzik group list] Fwd: Special group talk by Matteo Mariantoni on Thursday 29 , 11:00 a.m.

by sarah mostame

Dear group people, Matteo Mariantoni from UCSB (Martinis group on superconducting qubits) will be visiting Aspuru-Guzik group on Thursday, September 29. He will give a talk at 11:00 a.m., room CV233. Place: CV233 (Converse building) Date: Thursday September 29 Time: 11:00 - 12:00 a.m. Here is the title, abstract and references: *Implementing the Quantum von Neumann Architecture with Superconducting Circuits and the Photon Shell Game * *Matteo Mariantoni **Elings Prize Fellow California NanoSystem Institue - CNSI Postdoctoral Fellow Department of Physics, Broida Hall 4114, UC Santa Barbara, Santa Barbara, CA 93106-9530, USA* The von Neumann architecture for a classical computer comprises a central processing unit and a memory holding instructions and data. In this talk, I will present a quantum central processing unit (quCPU) that exchanges data with a quantum random-access memory (quRAM) integrated on a chip, with instructions stored on a classical computer [*]. I will show a proof-of-concept test of our quantum machine consisting of a code that involves seven quantum elements: Two superconducting qubits coupled through a quantum bus, two quantum memories, and two zeroing registers. In addition, I will show that single microwave photon Fock states can be coherently shuffled between three superconducting resonators, realizing the quantum-mechanical version of the well-known shell game [+]. Our results demonstrate that a scalable quantum processor using integrated superconducting circuits is within reach.

[Aspuru-Guzik group list] Announcement: Excitonics Seminar, Tues. Oct. 4. 3 pm, 36-428

by Cathy Bourgeois

Please post and forward to your group - Thanks Center for Excitonics Seminar Series Announcement TUES, October 4, 2011 3:00 PM RLE Haus Room: 36-428 Comparing the Primary Electron Transfer Process in Organic Photovoltaic Heterojunctions with Photosynthetic Reaction Centers Garry Rumbles National Renewable Energy Laboratory, University of Colorado Abstract This presentation will focus on some of the fundamental science associated with the rapidly emerging field of organic photovoltaics (OPV). It will include a discussion of how the OPV field is evolving, examine some of the fundamental scientific issues that underpin the subject, and will discuss how spectroscopy can help to understand these issues. The goal is to enable both a better understanding of how these systems function and consequently help to advance solar energy conversion efficiencies of future OPV devices. So-called organic photovoltaic devices have seen certified power conversion efficiencies increase from 2.5% in 2001 to ~9% in 2011. Close inspection of the strategies employed to realize this impressive improvement in performance reveal a common approach of synthesizing new donor polymers, fullerene acceptors and, in some cases, new device architectures. It is questionable as to whether this approach will result in a similar four-fold level of improvement over the next ten years. And it is this question that motivates the work that will be described. At the heart of all OPV devices is the donor-acceptor interface, where photogenerated excitons are dissociated into separated charge carriers. Using flash photolysis, timeresolved microwave conductivity as a tool for detecting mobile carriers, a number of recently-studied systems will be demonstrated. These may include systems that contain new conjugated polymers, novel derivatives of fullerenes, single-walled carbon nanotubes and colloidal quantum dots, to name a few. These studies will serve to highlight a fundamental issue that we have yet fully understand: how are these carriers created with such efficiency and yield, and in a system that does not immediately suggest that this is possible? The talk will therefore include a speculative discussion about how we might better understand this process by looking at the function of Nature's photosynthetic reaction centers. Bio Garry received his B.Sc (hons) in Chemistry with Electronics at the University of Southampton, United Kingdom in 1980 and his Ph.D in Molecular Photochemistry at the University of London, United Kingdom in 1984. Currently, he is a NREL Fellow in the Chemical and Material Science Center at the National Renewable Energy Laboratory in Golden, Colorado as well as Professor Adjoint in the Department of Chemistry and Biochemistry at the University of Colorado, Boulder, Colorado. His research interest is in next generation solar photoconversion concepts based on conjugated molecules and polymers combined and nanostructured species, with a focus on the fundamental photophysics of exciton dynamics and charge generation and recombination kinetics. Light refreshments will be served. The Center for Excitonics is an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science and Office of Basic Energy Sciences

Lithium-sulfur batteries offer a rich landscape in which to explore these fundamentals. In collaboration with experimental colleagues, we wish to understand and characterize the interactions of various polysulfide species dissolved in polymers through simulation. This will require an understanding of the underlying chemical equilibria and how they are modified due to interactions with the polymer electrolyte/electrode. In addition, establishing the important electrochemical interfaces in this system is key to making technological advances with this particular energy storage platform. Particular emphasis will be placed on simulation of x-ray spectroscopic data to provide much needed interpretation of measurements made at synchrotron light sources. https://lbl.taleo.net/careersection/2/jobdetail.ftl?lang=en&job=73664 ---------------------- This automatic notification message was sent by PSI-K ( http://cselnx9.dl.ac.uk:8080/portal) from the PSI-K site.
