Staged Hybridisation for Visual Quantum Reinforcement Learning via Knowledge Distillation

arXiv:2606.30520v1 Announce Type: cross Abstract: Visual environments are a demanding setting for quantum reinforcement learning (QRL): high-dimensional observations, unstable RL optimisation, and constrained variational quantum circuits (VQCs) are difficult to train jointly. This paper studies knowledge distillation (KD) as a staged hybridisation strategy for visual QRL. Instead of training a hybrid visual agent end-to-end from pixels, we first train a classical visual teacher, freeze its encoder as a feature interface, and distil the teacher's policy behaviour into compact downstream heads.

Why this matters
Why now

The increasing complexity of visual environments for quantum reinforcement learning (QRL) necessitates innovative training methodologies to overcome current limitations.

Why it’s important

This research addresses a critical hurdle in making quantum reinforcement learning practical for real-world visual applications, potentially accelerating quantum AI progress.

What changes

The proposed 'staged hybridisation' with knowledge distillation provides a more efficient and effective pathway to developing visual QRL agents, bypassing end-to-end training difficulties.
