[Theory-seminars] Theory seminar next Monday

[Astrid Hiller Blin]

Dear all,

Here is the information about next week's theory seminar:

*Theory seminar*
Monday, January 25th, 1:00 PM

*Felix Ringer* (Berkeley Lab) will talk about "Quantum simulation of open
quantum systems in heavy-ion collisions".

*Abstract:*

We present a framework to simulate the dynamics of hard probes such as
heavy quarks or jets in a hot, strongly-coupled quark-gluon plasma (QGP) on
a quantum computer [1]

Hard probes in the QGP can be treated as open quantum systems governed in
the Markovian limit by the Lindblad equation. However, due to large
computational costs, most current phenomenological calculations of hard
probes evolving in the QGP use semiclassical approximations of the quantum
evolution. Quantum computation can mitigate these costs, and offers the
potential for a fully quantum treatment with exponential speedup over
classical techniques. We report a simplified demonstration of our framework
on IBM Q quantum devices, and apply recently developed error mitigation
techniques. Our work demonstrates the feasibility of simulating open
quantum systems on current and near-term quantum devices, which is of broad
relevance to applications in both hot and cold nuclear matter.
