[Aspuru-Guzik group list] [Aspuru-meetings-list] group meeting tomorrow: Dr. Felipe Herrera

by Ryan Babbush

Hello Everyone, Tomorrow at 3pm in the Division Room, Felipe will tell us about his research. An abstract and title for this talk is provided below. "Designing quantum technologies with ultracold molecular gases and organic semiconductors" ================== This talk consists of two parts. First, I will introduce the physics of cold molecules in optical traps and describe our recently discovered method to prepare maximally entangled rotational bipartite states using a single sub-microsecond laser pulse. Entanglement detection methods and extensions to many particles will be discussed. In the second part of the talk I will sketch the plan for a project that aims to theoretically construct the first room-temperature photonic quantum gate using J-aggregates in optical microcavities. I will introduce some basic notions of classical and quantum nonlinear optics and then describe the expected challenges to overcome. Comments and suggestions from the group are encouraged. -- Ryan Babbush | PhD Student in Physics (949) 331-3943 | babbush(a)fas.harvard.edu Harvard University | Aspuru-Guzik Group 12 Oxford Street | Cambridge, MA 02138 _______________________________________________ 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] [qip] Martin Plenio Talk

by Shelby Kimmel

Hi Everyone, Thought people might be interested to know that Martin Plenio is giving a talk at Harvard on Wednesday at 4pm in Jefferson 356 or 250 (I've seen it published as being at both locations...at the ITAMP - Institute for Theoretical Atomic and Optical Physics seminar http://www.cfa.harvard.edu/itamp/gcalendar.html). I can't find the abstract anywhere so I don't know what the topic is, but he has done work related to entanglement theory and topography. You can read more about his research here: http://qubit-ulm.com/quantum-information-and-entanglement-theory/ Best, Shelby -- 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] Talk by Borja Peropadre: 03-26-2013 at 15:00 (strict time)

by Guerreschi, Gian

Dear all, Borja Peropadre is a PhD student in the group of Juan Jos?e Garc??a-Ripoll at CSIC in Madrid (Spain). http://quinfog.iff.csic.es/borja-peropadre He will visit our group next week, March 26th-29th. He is interested in our research and in discussing with us, therefore I will organize a schedule with private discussion on Tuesday after the seminar and on Thursday. Please, let me know if you are interested in discussing with Borja (otherwise I will try to select a representative sample based on our research topics). It is a pleasure to announce Borja's talk on Tuesday, March 26th, at 15:00 (strict time since at 16:00 we have to leave the room). -- Title: Controlling quantum systems in circuit QED designs. -- Abstract: The filed of circuit QED is widely considered the on-chip realization of cavity QED, where superconducting artificial atoms and microwave photons interact at the quantum level. The large tunability attainable in these solid-state devices, has made possible the achievement of the the so-called strong and ultrastrong coupling between light and matter. In this talk, I will show how we can take advantage of this large degree of control in circuit QED to manipulate the light-matter interaction, and ultimately the microwave photons in a resonator or propagating in an open transmission line. This offers a wide range of applications, ranging from quantum communications, condensed matter physics, to simulations in Quantum Field Theory. Best regards, Gian Giacomo

[Aspuru-Guzik group list] ITAMP topical lunch discussion: Thursday March 21st @ 12:00

by Charles Mathy

Dear Friends, On Thursday, March 21st, there will be an ITAMP topical lunch discussion. Tea Room (P-226) @ CfA (60 Garden Street) Time: 12:00-1:30 As always pizza will be served. Speaker: Johannes Feist (Universidad Autónoma de Madrid) Title: Signatures of quantum condensation in a diffractive array of plasmonic nanoparticles Abstract: Condensation of bosons, where a single quantum state is macroscopically populated, is a fascinating phenomenon spanning diverse areas of physics. It lies at the heart of superfluidity and superconductivity, as well as the Bose-Einstein condensation of ultracold dilute atoms, which was achieved close to twenty years ago. An important goal is to find systems in which condensation takes place at higher temperatures, even at or above room temperature. Bosonic quasi-particles in solids are excellent candidates due to their light effective masses, and signatures of condensation have been observed for semiconductor excitons and exciton-polaritons at temperatures of a few K, as well as for magnons and cavity photons at room temperature. I will present and discuss experimental signatures of quantum condensation of plexcitons at room temperature. Plexcitons are bosonic quasiparticles formed by strong coupling between organic molecule excitons and surface plasmon polaritons (quasi-bound modes confined on a subwavelength scale at metal-dielectric interfaces). The system I will discuss consists of a periodic array of metallic nanorods covered by a polymer layer doped with an organic dye. By increasing the plexciton density through optical pumping, we observe signatures of thermalization and condensation, such as the emergence of Bogoliubov-Goldstone modes, despite the nonequilibrium character of this driven and dissipative system. Looking forward to seeing you there, Charles Mathy

[Aspuru-Guzik group list] [Aspuru-meetings-list] AMP Seminar: THURSDAY MARCH 21, Femtosecond Laser-Induced Electron Diffraction...

by Gonzalo Gonzalez Abad

Dear colleagues, Please join us this Thursday for a seminar sponsored by the Atomic and Molecular Physics Division, Harvard-Smithsonian Center for Astrophysics. Complete schedule at http://www.cfa.harvard.edu/amp/events.html *** *Please let me know if you would like to meet with our speaker.* *** *2:00 PM Thursday, March 21, 2013* *Pratt Conference Room* *Author:* Prof. Chii-Dong Lin** Kansas State University *Title : *Femtosecond Laser-induced Electron Diffraction and Attosecond Autoionization of Fano Resonances ** *Abstract: *When molecules are exposed to an intense mid-infrared laser pulse, electrons that are released earlier in the pulse may be driven back to recollide with the parent ions to induce electron diffraction images. In the first part of this talk, I will discuss how one can use this laser-induced electron diffraction method to extract molecular structure, with sub-Angstrom spatial and a few-femtosecond temporal resolutions. In the second part of the talk, I will discuss how to describe and probe the time evolution of a Fano resonance with attosecond light pulses, and how to control the decay of Fano resonances, in analogy to electromagnetic induced transparency (EIT) in the time domain.
