Custom Penalty QAOA via Walsh-Hadamard Transform

Xin Wei LEE, Siong Thye GOH, Hoong Chuin LAU · 2026

Inequality constraints in combinatorial optimization are conventionally handled by introducing slack variables and quadratic penalties, which increase the qubit count and distort the optimization landscape. Slack-free formulations instead apply a nonlinear custom penalty function directly to the constraint, which are d …

Quantum Fidelity Landscape-Guided Prior Calibration for Single-Circuit QGAN Image Generation

Xue Yang, Rigui Zhou, Dax Enshan Koh et al. · 2026

Quantum Generative Adversarial Networks (QGANs) have emerged as representative generative models in the Noisy Intermediate-Scale Quantum (NISQ) era and have attracted increasing attention in quantum machine learning. However, most existing QGAN methods rely on patch-based decomposition strategies, which weaken the glob …
