Dear all,
This week will be the fourth "Harvard Quantum Information Group Meeting", which
will be held on Thursday, October 20th at 4:30 pm in Jefferson 250.
This week, Roy Garcia from Prof. Arthur Jaffe’s group will talk.
Title: Resource theory of quantum scrambling
Abstract: Quantum scrambling refers to the spread of local quantum information into the
many degrees of freedom of a quantum system. In this work, we introduce a resource theory
of scrambling which incorporates two mechanisms, "entanglement scrambling" and
"magic scrambling". We introduce two resource monotones called the Pauli growth
and the OTOC (out-of-time-ordered correlator) magic for these two mechanisms,
respectively. We use our resource theory to explain recent experimental observations of
magic. We also show that both resource monotones can be used to bound the decoding
fidelity in Yoshida's black hole decoding protocol. These applications provide an
operational interpretation of the resource monotones defined in this work.

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,
