Abstract

Variational Quantum Algorithms (VQAs), which combine expressive parameterized quantum circuits (PQCs) with classical optimization, are widely regarded as promising candidates for achieving quantum advantage on near-term quantum hardware. However, as system sizes scale beyond tens of qubits, VQAs face a critical obstacle known as the barren plateau (BP) phenomenon, in which the optimization landscape becomes exponentially flat. This not only hampers convergence but also poses a significant barrier to scalability—potentially triggering a ``quantum winter'' by stalling progress in quantum algorithm development. In this talk, He will present a hybrid quantum-classical framework designed to overcome barren plateaus and improve the trainability of PQCs. By addressing barren plateaus with scalable strategies, we aim to safeguard the momentum of quantum computing research and unlock practical applications on Noisy Intermediate-Scale Quantum (NISQ) devices.
