by Riley Hickman

Hi all, Jonny will speak at tomorrow's group meeting. His title and abstract can be found below. The Toronto side will meet in SS571 at 2:30pm. If you would like to join the meeting via Skype, please send me your information. Best, Riley -------------------------------------------------------------- Title: Autonomous Benchmarking for Quantum Chemistry Abstract: I will introduce you to the current collaborative work between the Aspuru-Guzik group (Riley, Théo, me) and the Head-Gordon group (Christopher Stein). The objective of our team project is to create a framework that allows routine benchmarking of quantum chemical models for large-scale computational studies. Without proper benchmarking, we have no control over the predictive accuracy of quantum chemical models used to (e.g.) produce labels for supervised learning problems. Our objective is to establish a good practice for data generation in virtual high-throughput applications such as molecular discovery.

[Aspuru-Guzik Group List] [qip] Talk: Brian Swingle @ IBM Cambridge (RSVP required)

by Ramis Movassagh

Dear all, We are happy to have Brian Swingle from University of Maryland as our first speaker at IBM Quantum (IBM Q) on Monday March 25th at 11 AM. *** For this and future such talks *RSVP is required* because of limited space and access to IBM. It is a <10 min walk from MIT. Please RSVP by sending an email to: ramis(a)us.ibm.com *Speaker: *Brian Swingle (UMD, Department of Physics) *Title:* A sparse model of quantum holography *Abstract: *We use a probabilistic pruning procedure to define new sparse quantum Hamiltonians from all-to-all connected Hamiltonians. By suitably adjusting the pruning probability, we obtain a model where the number of interaction terms scales like kN where N is the number of degrees of freedom and k is a parameter. Applied to the Sachdev-Ye-Kitaev (SYK) model, we obtain a sparse SYK (s-SYK) model which in the large N limit admits a 1/k expansion with the fully connected solution as the leading term. Applying the procedure to a supersymmetric version of SYK yields a model in which the fully connected saddle point is dominant down to the lowest temperatures. Hence, we exhibit a sparse quantum Hamiltonian which has a sector dual to a supersymmetric gravity theory. The sparsity gives additional technical benefits: classical and quantum simulation of the model is easier, at least for certain physical properties. In particular, the best previous algorithm for quantum simulation of SYK had complexity cost per unit time proportional to N^7/2; the analogous cost in the sparse model is of order N^2. Time: 11 AM, Monday March 25th Location: IBM Research, Room 5B-26 @ 75 Binney Street, Cambridge MA, 02142 https://goo.gl/maps/ajK6HZ8R1TC2 Host: Ramis Movassagh (ramis(a)us.ibm.com) _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik Group List] [qip] Fwd: Internship at Intel on Quantum Computing

by Aram Harrow

see below for a summer internship opportunity at Intel. no formal deadline but they will make their decisions very soon. let me know if you're interested and i'll pass your name along. ---------- Forwarded message --------- From: Guerreschi, Gian Giacomo <gian.giacomo.guerreschi(a)intel.com> Date: Wed, Mar 13, 2019 at 7:25 PM Subject: Internship at Intel on Quantum Computing To: Aram Harrow <aram(a)mit.edu> Dear Aram, I hope this email finds you well. I am writing to you since the lab I am part of is looking for a summer intern in quantum computing. As you may know, our lab performs research in several areas that may overlap with the background and interest of the graduate students in your group: · development of new quantum algorithms (most recently for QML and molecular spectroscopy) · simulation of variational quantum algorithms (like QAOA and VQE) and improvement of their protocols (novel classical optimization strategies, additional data pre-/post-processing, …) · compilation of quantum circuits via automatic tools We are located in Santa Clara (CA), the heart of silicon valley, as part of Intel Labs. We are looking for an outstanding graduate student to spend 3 months (ideally July-Sept 2019) in our group, working on development, analysis and simulation of quantum algorithms. In addition, we are interested to apply classical machine learning techniques (general adversarial networks, recurrent neural networks, etc) to analyze quantum algorithms and systems. I know that this is short notice for a summer internship, but we plan to interview candidates and make a choice in the next few weeks, so that everyone has time to make appropriate arrangements. Is there a candidate that you might be able to recommend for consideration? Best regards, Gian Giacomo PS: Our research tends to have a strong numerical component to it. Your group’s research is more focused on complexity considerations, but this internship may allow students to get in contact with HPC-style scientific coding if they are interested in numerical aspects of quantum computing research too. _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik Group List] TODAY, 11am- HQI Special Seminar - Leigh Martin

by Ploucha, Clare

Harvard Quantum Initiative Special Seminar Friday, March 8 11:00 AM Jefferson 256 Leigh Martin (Berkeley) Quantum feedback for measurement and control Many fundamental quantum limits arise from the inevitable disturbance caused by measurement. This disturbance imposes a barrier to precision measurement with no classical analog, but also provides a uniquely quantum mechanism for control. This talk explores both of these aspects in the context of quantum feedback. First, we discuss experimental results showing how feedback can take a measurement of phase to its fundamental limit. By continuously and adaptively changing measurement basis during readout of a single-photon signal, we enhance sensitivity over existing techniques and implement a canonical phase measurement. Second, we present theoretical methods for state control based on measurement back-action. We apply these methods to the task of entanglement generation and propose potential future experiments, including some that should be extremely robust to loss.

[Aspuru-Guzik Group List] HAPPENING NOW: Joint Quantum Seminar - Wednesday, March 6, 2019 @ 2:00 - Profs. Irfan Siddiqi

by Ploucha, Clare

Joint Quantum Seminar Wednesday, March 6, 2019 2:00 PM, Jefferson 250 *Please note time change. There will be no 10-minute talk* Prof. Irfan Siddiqi, University of California, Berkeley “Weak Quantum Measurements: From Art to Architecture” Canonical microwave frequency cavity quantum electrodynamical systems can be constructed from superconducting circuits, which thus enable a powerful laboratory for exploring foundational questions in quantum mechanics. When combined with near-quantum-limited photon detection, it is possible to enter the weak measurement regime where the continuous voltage output from the cavity can be used to construct individual quantum trajectories which statistically represent the most likely dynamical evolution of the artificial atom contained therein. Such techniques can be combined with fast feedback to change the measurement observable within the coherence time of the system, allowing one to probe quantities typically inaccessible to classical devices. As an example, I will discuss canonical measurements of the phase of a quantum signal which exceed the sensitivity afforded by heterodyne detection, and whose associated trajectories allow us to verify the acquisition of nearly-purely phase data. Guest Presentation will begin at 2:00 PM (no 10-minute talk) Refreshments will be provided Thank you, Samantha Dakoulas Faculty Assistant to Professors Lukin & Greiner & their groups Department of Physics 17 Oxford St., Lyman 324A Cambridge, MA 02138 P.
