Princeton University Thunch Talk

Cosmological simulations on classical computers are limited by time, energy, and memory usage. Quantum computers have the potential to exponentially improve computational costs and enable extremely large simulations that capture the whole dynamic range of structure in the Universe. However, not all computational tasks exhibit a 'quantum advantage'. Quantum circuits act linearly on quantum states, so nonlinearities (e.g. self-gravity in cosmological simulations) pose a significant challenge. In my Thunch talk, I will outline one potential approach to overcome this challenge and solve the (nonlinear) Schrodinger-Poisson equations for the evolution of self-gravitating dark matter, using a hybrid quantum-classical variational algorithm framework.
