[Aspuru-Guzik Group List] [qip] Dr. Masoud Mohseni, Friday, September 21, 2018 at 11:00 in the Haus Room, 36-428

by Aram Harrow

This will replace our regular 11am meeting. ---------- Forwarded message --------- **Note that this week’s seminar is on Friday.* Special OQE Seminar **Friday*, September 21, 2018 11:00 AM Haus Room, 36-428 Masoud Mohseni Google Quantum AI Laboratory Title: Quantum-assisted optimization and machine learning on NISQ devices Abstract: We present an overview of our progress on quantum optimization and machine learning at Quantum AI Lab at Google. In particular, we present an end-to-end quantum-assisted optimization engine on Google Cloud Platform. Our physics-inspired approaches use an interplay of thermal and quantum fluctuations to sample from unaccessible low-energy states of spin-glass systems that encode certain hard combinatorial optimization and probabilistic inference problems. We introduce structured droplet instances and show that our hybrid quantum-classical heuristic algorithms can improve over classical techniques, such parallel tempering, that rely on local updates. We also introduce universal discriminative quantum neural networks for classification and purification of quantum data. We train near-term small-scale quantum circuits to classify data represented by non-orthogonal quantum probability distributions using stochastic optimization techniques. This is achieved by iterative interactions of a classical processor with a quantum device to discover the parameters of an unknown non-unitary quantum map which can be implemented via a shallow quantum circuit. Similar small-scale quantum circuit learning could be used for verifying the quantum outputs of other shallow circuits, constructing structured receivers in quantum imaging/sensing, and designing quantum repeaters in quantum communication networks. Bio: Masoud Mohseni is a Senior Research Scientist at Google Quantum Artificial Intelligence Laboratory, where he develops novel quantum optimization and machine learning algorithms. A former research scientist and a principal investigator at the Research Laboratory of Electronics at MIT, Dr. Mohseni has been a scientific consultant at leading industry initiatives on unconventional computing. He obtained his Ph.D in physics in 2007 from University of Toronto. He then moved to Harvard University to complete a postdoctoral program in quantum simulation. Dr. Mohseni’s current research addresses some of the fundamental problems at the interface of artificial intelligence, quantum computing, and physics of complex systems. He has also made seminal contributions to the theory of coherent energy transfer in biological systems. He is an author and the leading editor of the first scientific book on Quantum Effects in Biology that has been published by Cambridge University Press.

[Aspuru-Guzik Group List] FW: [Perovskite-seminars] Perovskite Seminar on Sept 13 at 12:30PM in 33-116

by Catherine M Bourgeois

From: perovskite-seminars-bounces(a)mit.edu [mailto:perovskite-seminars-bounces@mit.edu] On Behalf Of Juan-Pablo Correa-Baena Sent: Tuesday, September 11, 2018 7:45 PM To: perovskite-seminars <perovskite-seminars(a)mit.edu> Subject: [Perovskite-seminars] Perovskite Seminar on Sept 13 at 12:30PM in 33-116 Please post and forward to your group(s). Perovskite Seminar on Thursday! The ‘Birth’, ‘Aging’ and ‘Life-Lengthening’ of Halide Perovskite By Yuanyuan (Alvin) Zhou, Assistant Professor (Research), School of Engineering, Brown University Date: September 13, 2018 Location: 33-116 Time: 12:30-1PM [image.png] Abstract: Halide perovskites have recently emerged as a new family of semiconducting materials that are revolutionizing the field of photovoltaics. The rapid development of perovskite-based solar cells is being led by advances in microstructural/compositional engineering of perovskite thin films. In this context, understanding the ‘birth’ (crystallization) and ‘aging’ (degradation), and developing new strategies for the ‘life-lengthening’ (stabilization) of perovskites are becoming the most significant research directions. In this talk, first, I will look at fundamental phenomena pertaining to nucleation & grain growth and grain-boundary evolution involved in the thin-film crystallization of perovskites from a materials-science perspective. Established scientific principles that govern these phenomena will be invoked in the context of specific examples. Based on these fundamentals, I will present a set of new synthetic strategies that have been recently developed in our group for scalable processing of high-performance large-area perovskite thin films and devices. Second, I will discuss the key role of grain boundaries in the degradation processes of perovskites, and show our recent progress in the grain-boundary tailoring that endows perovskites with new functionalities and enhances the perovskite stability. Finally, I will discuss the challenges and opportunities in the advanced characterization (high-resolution and in-situ/operando TEM, etc.) of perovskites for not only gaining a deep understanding of defects/microstructures, but also elucidating classical and non-classical phenomena pertaining to the crystallization, degradation, and stabilization of perovskites. The overall goal is to gain a deterministic control over the perovskite thin films with engineered microstructures/compositions for efficient PSCs that are also highly durable under environmental (heat/moisture/light) stresses. Biography: Yuanyuan (Alvin) Zhou is an Assistant Professor (Research) of Engineering since June 2016. He received his Ph.D. in Engineering (Materials Science) from Brown University in May 2016. He holds a B.S. in MSE from Xi’an Jiaotong University, and dual M.S. degrees in MSE from Xi’an Jiaotong University and Chemistry from Korea Research Institute of Chemical Technology. His research focuses on probing composition-microstructure-property-performance relationships of functional inorganic materials including halide perovskites for the development of high-performance photovoltaics, optoelectronics and electrochemical devices. ____________________________________ Juan-Pablo Correa-Baena, PhD Department of Energy Postdoctoral Fellow Massachusetts Institute of Technology (MIT) Cambridge, MA, USA Email: jpcorrea(a)mit.edu<mailto:jpcorrea@mit.edu> Web: https://www.jpcorreabaena.com<https://www.jpcorreabaena.com/> Twitter: @jpcorreabaena ******************************************************* Starting January 2019: Assistant Professor School of Materials Science and Engineering Georgia Institute of Technology Email: jpcorrea(a)gatech.edu<mailto:jpcorrea@gatech.edu> -- ____________________________________ Juan-Pablo Correa-Baena, PhD Department of Energy Postdoctoral Fellow Massachusetts Institute of Technology (MIT) Cambridge, MA, USA Email: jpcorrea(a)mit.edu<mailto:jpcorrea@mit.edu> Web: https://www.jpcorreabaena.com<https://www.jpcorreabaena.com/> Twitter: @jpcorreabaena
