Quantum neural networks
Variational circuits that act as trainable models on quantum hardware.
Application / Artificial Intelligence
Faster training, richer model spaces, quantum machine learning.
Quantum machine learning promises exponentially larger feature spaces and faster linear algebra — the two things that gate modern AI. It's early, but the theoretical ceiling is enormous.
In narrow tasks (kernel classification), small quantum systems already outperform their classical equivalents.
