<b class="">Title: </b>Quantum simulation of open quantum systems in heavy-ion collisions</div>
<div class=""><b class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: AvenirNext-Regular;">Abstract: </b><font color="#000000" face="AvenirNext-Regular" class=""><span style="caret-color: rgb(0, 0, 0);" class="">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.</span></font></div>
