**Quantum algorithms for quantum field theories** - Keith Lee

Quantum field theory provides the framework for the Standard Model of
particle physics and plays a key role in many areas of physics. However,
calculations are generally computationally complex and limited to weak
interaction strengths. I'll describe a polynomial-time quantum algorithm
for computing relativistic scattering amplitudes in massive scalar quantum
field theories. The algorithm applies at both weak and strong coupling,
achieving exponential speedup over known classical methods at high
precision or strong coupling. I'll then present the extension of this
work to fermionic quantum field theories, the new features of which
require different techniques. The study of such quantum algorithms may
also help us learn more about the nature of quantum field theory itself.
