Variational Manifold Engineering in Quantum Chemistry: Structural Challenges in Ansatz Design
This work presents a comparative structural analysis of major ansatz paradigms from the perspective of constrained variational manifold engineering and examines how each construction strategy encodes physical symmetries, balances expressibility and trainability, scales in parameter and measurement complexity, and responds to noise and hardware-induced constraints.
