[Aspuru-Guzik group list] The Eigenoffice

by Jarrod McClean

Fellow group members, The dust has settled after a long day of moving and at last, the quantum information team has been united in one room. Since the first floor MCB office was once called "New Siberia" but that name has now been appropriated by former "Siberia", we have chosen a new name for ourselves. From now on, we will be known as "the Eigenoffice". - The Eigenmembers

[Aspuru-Guzik group list] ITAMP lunch seminar - Crystal Senko, Harvard University (04/10)

by Richard Schmidt

Dear colleagues, this week we are happy to have Crystal Senko from the Lukin group as speaker at our weekly seminar. Kind regards, Richard and Swati ITAMP Topical Lunch Discussion Date: Friday, April 10th 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: Crystal Senko, Harvard University (Lukin group) Title: Quantum simulations of many-body spin dynamics with trapped ions Abstract: Trapped atomic ions are a powerful and versatile platform for emulating quantum spin systems. I will give a brief overview of the tools that are currently available to experiments, particularly the various spin models that can be generated by applying spin-dependent optical dipole forces to a chain of interacting ions. We have performed a variety of experiments using this toolkit, including measurements of the many-body energy spectrum [1] and of the propagation of spin correlations after a sudden quench [2], as well as demonstrated a quantum integer-spin chain [3]. This system holds promise for scaling quantum simulations up to several tens of spins, a size where many classical computations become intractable. [1] C. Senko et al, Science 345, 430 (2014) [2] P.

[Aspuru-Guzik group list] [Aspuru-meetings-list] Group Meeting 4/9, 2:30pm, Div. Room

by Jennifer Wei

Hi everyone, Tomorrow's group meeting will be given by Dmitry. Please see below for the title and abstract of his talk. Jennifer ------------------------------- Title Search For A Perfect Leaving Group In Nucleic Acid Polymerization Abstract Non-enzymatic template-directed RNA replication is fundamental to the RNA World model of the origin of life. The efficiency and accuracy of the process still remain far from what is necessary for the integration with protocell model. There are multiple problems that have to be resolved. One of them is a requirement for the activation of the monomer units in order to make polymerization thermodynamically favorable. Activated monomers, however, experience degradation due to hydrolysis and cyclization. I will discuss a recent effort in computational screening of the nucleophilic leaving groups for non-enzymatic RNA oligomerization. The goal of the screening is to identify the candidates that have more favorable kinetic characteristics in the competing reactions of dimerization and hydrolysis than currently used 2-methylimidazole. _______________________________________________ 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] DO NOT EXIT THROUGH BACK DOOR -- NEW Siberia

by Marlon Cummings

Seems someone is exiting through that back door -- Not allowed. That door is an emergency exit and does not close properly. Meaning, if you leave, it does not shut fully, so someone can easily come by and steal your stuff! Don't use that back door. Marlon. -------------- Marlon G.

[Aspuru-Guzik group list] [IACS-events] REMINDER: IACS Seminar: "Big Data, Geospatial Computing, and My 2 Cents in an Open Data Economy"--- Friday 4/10 ***NEW TIME*** 12-1PM

by Baker, Natasha

Date: Friday, April 10, 2015 Time: Talk: 12-1pm (lunch will be provided during seminar) Location: Harvard SEAS, Maxwell Dworkin Bldg. Room G115, 33 Oxford Street, Cambridge MA 02138 Speaker: Budhendra Bhaduri, Corporate Research Fellow & Leads the Geographic Information Science and Technology (GIST) group at Oak Ridge National Laboratory Title: Big Data, Geospatial Computing, and My 2 Cents in an Open Data Economy Abstract: In this rapidly urbanizing world, unprecedented rate of population growth is not only mirrored by increasing demand for energy, food, water, and other natural resources, but has detrimental impacts on environmental and human security. Much of our scientific and technological focus has been to ensure a sustainable future with healthy people living on a healthy planet where energy, environment, and mobility interests are simultaneously optimized. Current geoanalytics are limited in dealing with temporal dynamics that describe observed and/or predicted behaviors of entities i.e. physical and socioeconomic processes. With increasing temporal resolution of geographic data, there is a compelling motivation to couple the powerful modeling and analytical capability of a GIS to perform spatial-temporal analysis and visualization on dynamic data streams. However, the challenge in processing large volumes of high-resolution earth observation and simulation data by traditional GIS has been compounded by the drive towards real-time applications and decision support. The ability to observe and measure through direct instrumentation of our environment and infrastructures, from buildings to planet scale, coupled with explosion of data from citizen sensors, brings much promise for capturing the social/behavioral dimension. Additionally, it provides a unique opportunity to manage and increase efficiencies of existing built environments as well as design a more sustainable future. This presentation will explore the intriguing developments in the world of Big Data, geospatial computing, and plausible ways citizens can all become part of the open data economy for advancing science and society. This talk is also part of the Geography Colloquium<http://gis.harvard.edu/events/seminar-series/colloquium> hosted at the Center for Geographic Analysis. Speaker Bio: Dr. Budhendra (Budhu) Bhaduri is a Corporate Research Fellow and leads the Geographic Information Science and Technology (GIST) group at Oak Ridge National Laboratory. He is the founding director of the Oak Ridge Urban Dynamics Institute and holds professorial appointments with the University of Tennessee, Knoxville.

[Aspuru-Guzik group list] Prof Feiguin Visit Tomorrow

by Thomas Markovich

Hi All, Professor Adrian Feiguin from Northeastern will be visiting the group tomorrow as part of the Greater Boston Area theochem series. He's an expert in quantum information as he was the theoretician in Awschalom's group, and helped to develop DMRG with Stephen White. I'm sure we can find quite a bit of overlap between him and the group. I contacted other groups last week, but no one has gotten back to me about meeting with him, so let's see if we can fill his schedule! I've also got lunch spots, so please let me know if you're interested. His abstract is below Thomas Abstract: "The study of models of strongly correlated electrons is a difficult problem since methods based on perturbation theory generally fail. The lack of controlled and well-behaved approximations has led physicist and chemists to study these systems using numerical techniques. In 1992, Steven White invented the Density Matrix Renormalization Group method. With roots that can be traced to Wilson's Renormalization Group, this technique has proven to be remarkably effective computational tool to calculate static, ground state properties of low-dimensional strongly correlated systems. During the past ten years, the DMRG has experienced an unprecedented evolution. Through a convergence with quantum information ideas, we now have a much better understanding of its range of applicability, and the consequences of quantum entanglement on the effectiveness of the method. In a subsequent development we adapted it to solve the time-dependent Schroedinger's Equation. I will present both algorithms, discuss different applications, and show results for spin and electronic transport in nano-structures, decoherence in open quantum systems, and spectral properties of low dimensional electronic systems. I will finally show how the method can be extended to imaginary time to study thermodynamics and finite-temperature properties."

by Edward Farhi

Subject: Reminder: Announcement for Harvard Physics Colloquium Speaker John Martinis, UCSB, on 04/06/15 Date: April 3, 2015 at 1:47:46 PM EDT Harvard Physics Colloquium Monday, April 06, 2015 4:15 p.m.-5:15 p.m. in Jefferson 250 Tea served in Jefferson 450 @ 3:30 p.m. “Bit-flip Error Correction with Superconducting Xmon Qubits” John Martinis UCSB For announcement poster please go to: http://www.physics.harvard.edu/events/colloquium.pdf One of the outstanding challenges of quantum computation has been the realization of scalable qubits with high fidelity for all necessary operations. Here I discuss the design of a linear chain of 9 superconducting Xmon qubits that allows initialization, single and two qubit gates, and fast repetitive and simultaneous measurement with fidelity in the 99%-99.9% range. This performance has allowed us to perform bit-flip error correction with 8 repetition cycles that leads to improved lifetime of the state. The use of error correction based on the surface code enables all errors, both data and measurement, to be corrected to 1st and 2nd order. *********************************************** Edward Farhi Cecil and Ida Green Professor of Physics Director Center for Theoretical Physics Massachusetts Institute of Technology Building 6 room 300 Cambridge MA 02139 617 253 4871 *********************************************** _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip
