Researchers Build Faster Quantum State Preparation Technique

Can preparing complex quantum states always demand exponentially increasing computational resources? A new technique called ‘nucleation’ demonstrably improves upon existing methods for building these states on digital quantum computers, specifically, for simulating a two-dimensional magnetic system. This approach begins with a simple solvable lattice and incrementally grows it, potentially easing resource demands for future algorithms.
