Abstract
We summarize current and future applications of quantum information science
to theoretical high energy physics. Three main themes are identified and
discussed; quantum simulation, quantum sensors and formal aspects of the
connection between quantum information and gravity. Within these themes, there
are important research questions and opportunities to address them in the years
and decades ahead. Efforts in developing a diverse quantum workforce are also
discussed. This work summarizes the subtopical area Quantum Information for
High Energy Physics TF10 which forms part of the Theory Frontier report for the
Snowmass 2021 planning process.
