Abstract, Event Details: 

Quantum computers provide a unique way of computing real-time correlators from

first principles, a task not yet achievable on classical computers due to the

sign problem. In this talk I discuss algorithms for obtaining various real-time

observables on a quantum computer in field theory, with an emphasis on SU(3)

gauge theory, relevant for nuclear physics. Many of these algorithms have

requirements that are entirely unrealistic in the near- and medium-term. As a

result, substantial efforts have gone to reducing the computational cost one

must pay in order to extract useful QCD observables. I outline some of these

efforts, and argue that determining transport coefficients of hot Yang-Mills

may be feasible sooner than most other calculations.
