Breaking the One-Dimensional Expressibility-Trainability Tradeoff

Kyoungho Cho, Yu-Seong Jeon, Jinhyoung Lee, Jeongho Bang

Expressive parameterized quantum circuits (PQCs) are often designed under a dilemma: the growth of expressibility and entangling power (EP) that improves Hilbert-space coverage is also expected to randomize an ansatz and activate barren-plateau (BP) conditions. We show that this…Read more
