Neutrino-Neutrino Interactions and Quantum Computers

The formalism of open quantum systems is critical for describing weakly interacting quantum systems that compete with environmental “noise”. The proposal uses effective field theory to describe open quantum systems, with applications in neutrino physics and in the simulation of non-Hermitian dynamics using quantum computers. The project develops new theoretical tools to systematically separate problems into parts that can be calculated analytically or using classical simulation, and those that can be efficiently treated by quantum simulation. This will determine which problems can be attacked with near-term quantum simulations.
