[Aspuru-Guzik Group List] Group meeting, June 16, 3:30 PM, Div Room

by Ian Kivlichan

Hi all, Tomorrow at group meeting we have Raffaele Santagati from Bristol speaking. See below for his abstract. See you there, Ian ----------------- Silicon photonics with the ability of integrating lasers, photon pair sources, modulators, filters and detectors is a promising technology for the development of integrated quantum photonics. In this talk I will present our most recent experimental results going from the generation and analysis of entangled states on-chip to the application of silicon photonics to quantum information processing and quantum simulation.

[Aspuru-Guzik Group List] visitor from Bristol: Raffaele Santiagi

by Borja Peropadre

Hi guys, Raffaele Santagati, postdoc researcher at the centre of quantum photonics in Bristol, is visiting us tomorrow Thursday and also on Friday --note that this is not a postdoc interview. He has mostly quantum optics and quantum computing background. Please check out his google scholar profile: https://scholar.google.co.uk/citations?user=bgcVso0AAAAJ&hl=en We have planned the following schedule for him: https://docs.google.com/document/d/1d25tWxEbptEV6RZ_BxYaOHKfwvKzoSCEfuwpylv… As you see, there are many free spots on Friday. If you are interested in meeting with him, please choose any available time. He will also give a talk in the usual group meeting schedule (I guess Ian will send an email with the title and abstract). Best, Borja

[Aspuru-Guzik Group List] [qip] seminar on Tuesday

by Edward Farhi

Please join us at 12:00PM, on Tuesday, June 14, 2016 for a Special Condensed Matter Physics Seminar with: Pedram Roushan, University of California-Santa Barbara, Google Inc., The seminar will be held in the Duboc Room 4-331 Please see the details of Pedram’s presentation below. Title: Chiral groundstate currents of interacting photons in a synthetic magnetic field Abstract: The intriguing many-body phases of quantum matter arise from the interplay of particle interactions, spatial symmetries, and external fields. Generating these phases in an engineered system could provide deeper insight into their nature and the potential for harnessing their unique properties. However, concurrently bringing together the main ingredients for realizing many-body phenomena in a single experimental platform is a major challenge. Using superconducting qubits, we simultaneously realize synthetic magnetic fields and strong particle interactions, which are among the essential elements for studying quantum magnetism and fractional quantum Hall (FQH) phenomena. The artificial magnetic fields are synthesized by sinusoidally modulating the qubit couplings. In a closed loop formed by the three qubits, we observe the directional circulation of photons, a signature of broken time-reversal symmetry. We demonstrate strong interactions via the creation of photon-vacancies, or "holes", which circulate in the opposite direction. The combination of these key elements results in chiral groundstate currents, the first direct measurement of persistent currents in low-lying eigenstates of strongly interacting bosons. The observation of chiral currents at such a small scale is interesting and suggests that the rich many-body physics could survive to smaller scales. We also motivate the feasibility of creating FQH states with near future superconducting technologies. Our work introduces an experimental platform for engineering quantum phases of strongly interacting photons and highlight a path toward realization of bosonic FQH states.

[Aspuru-Guzik Group List] ML-meeting : Adverserial Networks, today 2pm Acapulcoplex

by Benjamin Sanchez Lengeling

Hi all, Today we will have a meeting on generative adversarial networks. We will see how we can create generative models by having models compete with each other in different roles. We will see how to apply this strategy in a 1D case and give a feeling for how to treat mages. A good link for motivation is the cat-generator: https://github.com/aleju/cat-generator Neural network generated cat portraits: https://raw.githubusercontent.com/aleju/cat-generator/master/images/random_… Hope to see you there Ben

[Aspuru-Guzik Group List] Theochem Organizational meeting Tuesday and Host Volunteers

by Jennifer Wei

Hi everyone, The theochem organizational meeting will be happening on Tuesday, 6/14, at John Harvard's at 6:00p. This is the meeting with MIT and BU where we discuss who we will invite for the next season of theochem. If you're interested in attending, please let me know so I can make the RSVP. If you cannot make the meeting, but have suggestions for who to invite, please let me know that too, and we can consider it at our meeting. *We also need volunteers to host! *Hosts are really important to ensuring theochem runs smoothly. If enough people volunteer, no one will have to host more than once a semester. *Please let me know if you can help host next year.* Thank you, sorry for the weekend email. I'll send a reminder Monday evening. Jennifer

[Aspuru-Guzik Group List] Fwd: Postdoctoral position: intermediate band materials. Please forward.

by Alan Aspuru-Guzik

---------- Forwarded message ---------- From: *Jacob Krich* <jkrich(a)uottawa.ca> Date: Friday, June 10, 2016 Subject: Postdoctoral position: intermediate band materials. Please forward. To: Jacob J Krich <jkrich(a)uottawa.ca> Dear Colleagues, I am looking for a postdoctoral fellow for a 2 year (extendable to a third year) position performing theoretical work on intermediate band materials for infrared photodetectors and photovoltaics in the University of Ottawa physics department. Applications will be accepted until the position is filled, and the ideal start date is in Fall 2016. The research involves a combination of analytical and numerical modelling of intermediate band devices, in close collaboration with the experimental groups of Jeffrey Warrender at Benét Laboratories and Karin Hinzer at uOttawa. Intermediate band materials (semiconductors with a large number of allowed levels deep inside their band gaps) have only recently been created, and many of their fundamental physical properties are not understood, presenting rewarding opportunities for theoretical research. Silicon-based intermediate band materials have strong IR absorption, and our goal is to understand what combination of material properties is most important to turn that absorption into extractable carriers, making effective IR photodetectors and high efficiency solar cells. We will be developing analytical and numerical models of intermediate band devices and will also help to design and interpret characterization experiments for these materials. The successful candidate will have a PhD in physics, electrical engineering with a focus on semiconductor devices, materials science, or a related field. Prior experience with intermediate band materials, photodetectors, or solar cells is not required. Applications from those with an experimental background are welcome, but strong interest and proficiency in analytical and numerical modelling is required. Proficiency with programming (in any language) is desirable. Interested applicants should send their cv, and arrange for two references to be sent to Jacob Krich, jkrich(a)uottawa.ca <javascript:_e(%7B%7D,'cvml','jkrich(a)uottawa.ca');>. Please forward this information to anyone who may be interested and feel free to contact me with questions. I am also seeking a graduate student at either MSc or PhD level to work on this and related projects. Thank you and best regards, Jacob -- Assistant Professor Physics Department and School of Electrical Engineering and Computer Science University of OttawaOffice: ARC 408tel: 613 562 5800 x6963http://mysite.science.uottawa.ca/jkrich/ -- 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
