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…>.

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

“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.

Dear quanta,
A few of us have conflicts this Friday, so let's skip.
On May 29, we'll have Matt Hastings tell us about his adiabatic oracle
result <https://arxiv.org/abs/2005.03791>.
On June 5, we'll have Jeff Schenker tell us about his paper with Ramis on
ergodic quantum channels <https://arxiv.org/abs/2004.14397>.
I'll write closer to the date with zoom links.
aram
