Gregor is giving a talk today on his masters work - Div room 2:30. I would appreciate it if you could make it, as the work has implications for many of us in the group - not just the materials people (although it is especially interesting to them). All the best Ed

[Aspuru-Guzik group list] Talk this Friday: Gregor Simm

by Edward Pyzer-Knapp

Hi all On Friday at 2:30 Gregor will be giving a talk in the div room on his masters project, before he heads back to ETH at the end of the month. Gregor's work is on calibrating the results we get from quantum calculations to experimentally relevant values. His work is particularly neat because it gives you an uncertainty as well as a calibration value, so you know when you are straying far from the applicability of the model. Anyway, enough spoilers. Please come and watch - it will be especially interesting for those of you who dabble in materials discovery! And doughnuts will be provided. What more could you want?! All the best Ed

[Aspuru-Guzik group list] ITAMP lunch seminar- Ephraim Shahmoon, Harvard University (03/20)

by Richard Schmidt

Dear colleagues, this week (tomorrow) we are looking forward to a talk by Ephraim Shahmoon. Kind regards, Richard and Swati ITAMP Topical Lunch Discussion Date: Friday, March 20th Time: 12:00-1:30 pm Pizza will be served. Location: B-106 @ Center for Astrophysics (60 Garden Street) Directions: after entering the lobby of the CfA, turn right to enter the hallway of the B building. In the hallway, turn right again, and B-106 is there. Speaker: Ephraim Shahmoon, Harvard University Title: Dipolar interactions in waveguides: From Casimir forces to nonlinear optics Abstract: Dipolar interactions lie at the basis of a variety of phenomena in physics and chemistry, ranging from fundamental quantum vacuum forces and energy transfer all the way to emerging quantum technologies. This talk concerns the important possibility to drastically modify these dipole-dipole interactions, thus potentially affecting much of the above phenomena: Since the interactions between dipoles are mediated by (virtual) photon modes, they can be enhanced by considering dipoles embedded in geometries that confine these modes. In this context, I will present our results on the possibilities for giant quantum vacuum forces via transmission lines, and for extremely nonlocal optical nonlinearities based on atomic interactions in a fiber. --------------------------- Dr. Richard Schmidt Institute for Theoretical Atomic, Molecular, and Optical Physics (ITAMP) Harvard-Smithsonian Center for Astrophysics MS-14 60 Garden St. Cambridge, MA 02138 U.S.A. richard.schmidt(a)cfa.harvard.edu Tel. +1 (617) 496-7610 Fax +1 (617) 496-7668

[Aspuru-Guzik group list] [Aspuru-meetings-list] Group Meeting, Thursday, 2:30pm, Div Room

by Jennifer Wei

Hi Everyone, Tomorrow's group meeting will be given by Jon. Please see below for the abstract of his talk. Also note: *next week's group meeting will be Wednesday, March 25, at 10:30am*. I will send another reminder out early next week. Thanks, Jennifer ------------------------------ In this talk we will discuss the decomposition and compilation of diagonal operators in the gate model of quantum computation. Specifically we will cover the decomposition using the Walsh System, and the Phase Context Decomposition algorithm. We will discuss the benefits associated with each system and will discuss some open questions that have arisen while exploring the space of circuits these decompositions can produce. We will begin with an introduction/review of the Walsh Decomposition and how it is used for building quantum circuits for diagonal operators. Then we will introduce and cover the phase context decomposition and introduce the concept of a cascaded entangler network which provides an alternative but completely complementary approach to the Walsh system for decomposing diagonal operators efficiently. We will conclude with a discussion on the performance of the two methods against some randomly generated sample operators. _______________________________________________ Aspuru-meetings-list mailing list Aspuru-meetings-list(a)lists.fas.harvard.edu https://lists.fas.harvard.edu/mailman/listinfo/aspuru-meetings-list

[Aspuru-Guzik group list] [theochem-announce] Theoretical Chemistry seminar TODAY 3/18 @ 4 PM, 4-163

by Michael Mavros

Hi all, There will be a theoretical chemistry seminar TODAY by Prof. Alan Aspuru-Guzik at Harvard University. The talk title and abstract can be found below. Hope to see you there! *"A decade of quantum computing for quantum chemistry"* Alan Aspuru-Guzik Professor Department of Chemistry and Chemical Biology Harvard University The last time I spoke about quantum computing and chemistry to a theoretical chemistry audience in the Boston area was at this very same seminar back in 2006 or 2007. In this seminar, I will give an update on what has happened in the last 10 years since the original full configuration interaction quantum chemistry proposal (Aspuru-Guzik, et al., Science, 2005). I will give a 2-hour talk (with more details than usual) of why large-enough quantum computers will be relevant, perhaps game-changing for chemistry. I will discuss several ways of solving the electronic structure problem in quantum computers, and also their relevant experimental realizations, either proposed or actually carried out in small quantum devices. An important point relevant to these, is their scaling and potential for realization in the near future assuming quantum computers continue to develop rapidly. I will discuss this interesting aspect. I will also briefly discuss applications in optimization problems (e.g. folding proteins) and quantum dynamics. If time permits, I will discuss the use of our recent proposed Boson Sampling experimental setup to simulate molecular vibrionic spectra. -- Michael Mavros Department of Chemistry, Massachusetts Institute of Technology _______________________________________________ theochem-announce mailing list theochem-announce(a)mit.edu http://mailman.mit.edu/mailman/listinfo/theochem-announce

[Aspuru-Guzik group list] Fwd: Announcement for Harvard Physics Colloquium Speaker Wojciech Zurek, Los Alamos, NM on 03/23/15

by Martin Blood-Forsythe

Dear colleagues, Next Monday's Physics colloquium may be of interest to many of you. See below. Best wishes, -Martin ---------- Forwarded message ---------- From: Maynard, Dayle <maynard(a)fas.harvard.edu> Date: Tue, Mar 17, 2015 at 5:06 PM Subject: Announcement for Harvard Physics Colloquium Speaker Wojciech Zurek, Los Alamos, NM on 03/23/15 Harvard Physics Colloquium Monday, March 23, 2015 4:15 p.m.-5:15 p.m. in Jefferson 250 Tea served in Jefferson 450 @ 3:30 p.m. *“Decoherence and Quantum Theory of the Classical.”* Wojciech Zurek Los Alamos, NM For announcement poster please go to: http://www.physics.harvard.edu/events/colloquium.pdf I will describe three insights into the transition from quantum to classical. After a brief discussion of decoherence I will give (i) a minimalist (and decoherence-free) derivation of preferred states. Such pointer states define events (e.g., measurement outcomes) without appealing to Born's rule. Probabilities and (ii) Born’s rule can be then derived from the symmetries of entangled quantum states. With probabilities at hand one can analyze information flows from the system to the environment in course of decoherence. They explain how (iii) robust “classical reality” arises from the quantum substrate by accounting for all the symptoms of objective existence of preferred pointer states of quantum systems through the redundancy of their records in the environment. Taken together, and in the right order, these three advances (i)-(iii) elucidate quantum origins of the classical. W. H. Zurek, Physics Today 10, 44-50 (2014).
