Hardware-Efficient Ground-State Preparation using Variational Imaginary-Time Majorana Evolution
This research introduces Variational Imaginary-time Majorana Evolution (VIME), a new classical pre-training algorithm for preparing molecular ground states. VIME combines imaginary-time evolution with Majorana propagation using a single compiled graph to efficiently find the lowest energy state. It significantly reduces computational costs, requiring vastly fewer CNOTs and lower circuit depths than existing methods for large molecules.
