Dear all,
This week will be the final "Harvard Quantum Information Group Meeting” this
semester, which will be held on Thursday, December 1st at 4:30 pm in Jefferson 250.
This week, Eric Anschuetz from MIT will talk.
Title: Contextuality for Quantum Advantage
Abstract: Quantum machine learning models have been widely studied in recent years, given
their potential practical utility and recent results regarding their ability to
efficiently express certain classical data. However, analytic results to date typically
rely on assumptions and arguments from complexity theory. Due to this, there is little
intuition as to the source of the expressive power of quantum neural networks or for which
classes of classical data any advantage can be reasonably expected to hold. In this
tutorial, I will discuss recent results (arXiv:2101.08354, arXiv:2209.14353) studying the
relative expressive power between a broad class of machine learning models and a class of
recurrent quantum models. I will discuss how the presence of quantum contextuality can be
used to show an unconditional memory separation in the expressivity of quantum machine
learning models. Additionally, I will discuss the implications of these techniques in
showing quantum advantages on practical translation data sets.

for the next few meetings.
The meeting is open to everyone at Harvard interested in quantum information, including
those in condensed matter physics, AMO physics, high energy physics, computer science,
chemistry, etc. The format includes weekly tutorials (by both external and internal
speakers) of contemporary topics in quantum information and quantum computing, aimed for a
broad scientific audience.
We will also try to foster connections between different groups at Harvard which are
interested in or involved with quantum information, and build a broader community.
Hope to see you all there. If you would like to join the mailing list for this meeting,
please e-mail harvardqimeeting(a)gmail.com <mailto:harvardqimeeting@gmail.com> which
will add you.
