QALM: Escaping Local Minima via Interleaved Exploration and Exploitation in Quantum Circuit Optimization
Aidan Wagner, Mingkuan Xu, Pengyu Liu +2
Quantum circuit optimizers face a fundamental limitation in how they tolerate temporary cost increases. At one extreme, greedy rule-based optimizers immediately apply any cost-redu…

Low-Overhead Surface Code with Delayed Atom-Loss Detection via Pauli Envelope
Pengyu Liu, Shi Jie Samuel Tan, Eric Huang +3
Atom loss is a major error source in neutral-atom quantum computers, accounting for over 40% of the total physical errors in recent experiments. Its nonlinear and correlated nature…
