[Aspuru-Guzik Group List] [qip] Physical Review event - Journal Club - Mon, June 22

by Aram Harrow

I'm passing along this event announcement from people I know at the APS. ------ The Physical Review Journals are hosting an interactive event to promote and engage early-career scientists. The meeting will essentially be a virtual Journal Club, happening on June 22nd at 11 am EDT. It will consist of a 20 min presentation of a paper (by the author himself) followed by 40 min of questions. Several of the authors will be at the meeting, and the interactive platform (i.e. the participants are allowed to have their camera and microphone on), make this a rare opportunity. On June 22 at 11AM EDT, APS will host author Christopher S. Wang of Yale University, along with several of his co-authors for a discussion of their recently published *Physical Review X *paper: “Efficient multiphoton sampling of molecular vibronic spectra on a superconducting bosonic processor <https://journals.aps.org/prx/accepted/bc070K5dZa512a0e74716ee3f2da89a36a0a1…> .” Hear details about breakthrough quantum research and meet new people in this free Journal Club discussion, which includes a brief presentation from the researchers followed by a question-and-answer session where all registrants can discuss technical aspects of the research, challenges in the field of quantum information science and technology, and more with the authors. Early-career scientists can especially benefit from this interactive presentation of exciting journal research, which will be moderated by Marissa Giustina from Google Research. This is a rare opportunity to discuss recently published research with the authors themselves. Space is limited. Please register only if you can attend live. Registration is required and the space is limited. The full information about it is on the registration website at Eventbrite <https://www.eventbrite.com/e/physical-review-journals-club-presented-by-the…>. _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik Group List] HQI’s Commitment to Diversity, Inclusion, and Belonging

by Ploucha, Clare

Dear HQI Community, We write today to affirm the Harvard Quantum Initiative’s commitment to diversity, inclusion, and belonging and share with you our approach to advancing this effort in quantum science and engineering (QSE). Black Lives Matter. HQI condemns racism, racial injustice, racially-targeted violence and discrimination. We celebrate the common bonds that unite us in our exploration of the world, and are committed to developing an environment of respect and opportunity. We will work to develop programs that will deepen our commitment and advance diversity and inclusion in quantum science and engineering. We believe that substantial, enduring change is possible only when our community engages in sustained reflection, discussion, and action. We invite you, our community members, to share your ideas of how we can make change by responding to this message, or emailing hqidirectors(a)gmail.com<mailto:hqidirectors@gmail.com>. In order to align our programming with our goal of recruiting a larger cohort of talented under-represented minority students into the field of QSE, HQI proposes the creation of a one-year post-baccalaureate program focused on targeting underrepresented minority students in Physics, Applied Physics, Computer Science and Engineering fields related to quantum research. This program will accomplish two goals at once, bringing students that will pursue a PhD to a scholarship level so they can “hit the ground running” and also make them competitive in the admissions process by demonstrating skill and interest in research and providing an additional evaluative letter from a well-known professor in the field. It will also provide mentoring experiences that will benefit both the students in the program and our current graduate students in QSE, who will be invited to serve as mentors. In launching this program, we will learn from best practices from similar programs and work with the HQI community to solicit ideas and support to ensure the program’s success. We invite you to read the draft program outline and share your suggestions here: https://docs.google.com/document/d/1viXlg_UB9v2qfhBUrEcBKpKjVYlNxps23ed4eHj…. We look forward to hearing your feedback on the proposed plan, and on how we might work together to strengthen our commitment going forward. Thank you, John Doyle Evelyn Hu Mikhail Lukin HQI Co-Directors

[Aspuru-Guzik Group List] [qip] Fwd: Crosson seminar Tuesday

by Aram Harrow

this talk is tomorrow. “The sign problem and its relation to the spectral gap of quantum many-body systems” Elizabeth Crosson, University of New Mexico Abstract: The partition function of a quantum system without a sign problem can be represented by a path integral in which every amplitude is efficiently computable and nonnegative, which is a substantial simplification from the interference of complex amplitudes in the general quantum case. In quantum computing the presence of a sign problem has been recast as a virtue, because it helps to increase the complexity of the quantum system beyond the range of classical simulation. This is particularly important for quantum adiabatic algorithms based on ground states, where the run time depends on the scaling of the spectral gap above the ground state. This motivates us to study the relation of the sign problem to the spectral gap, using methods such as random matrix theory and spectral graph theory. The latter relates the discrete geometry of ground states (in a world where vertices are basis elements and edges are Hamiltonian matrix elements) to the level spacings in the low energy spectrum using the higher-order signed Cheeger inequalities. This talk will include analytical results from 1703.10133 and 2004.07681. ---------- Forwarded message --------- From: Arthur Jaffe <arthurjaffe(a)me.com> Date: Mon, Jun 8, 2020 at 11:21 AM Subject: Crosson seminar Tuesday To: Arthur Jaffe <arthurjaffe(a)me.com> Join by Zoom at *https://harvard.zoom.us/j/779283357 <https://urldefense.proofpoint.com/v2/url?u=https-3A__harvard.zoom.us_j_7792…>* _______________________________________________ _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip
