Abstract: Quantum mechanics has allowed tremendous progress in the theoretical understanding of our universe. In this endeavor, computational Monte Carlo techniques have proved vital to extracting some properties of strongly-correlated materials and nuclear physics. Alas, sign problems----when a sampling distribution fails to be a well defined probability-- stymie these methods in systems like the high temperature superconductors, neutron stars, and the time evolution of particle scattering. In this talk, I discuss the origin of sign problems and the recent developments in complexification and quantum computing that are helping to address them.
