A Unified Framework of Parameter-shift Rule Based on Heisenberg Picture
H. Nagayoshi, Warit Asavanant, Ryuhoh Ide, Akira Furusawa · 2025
We propose a framework of parameter-shift rule for variational quantum algorithms that provides a unified description of previous extensions, together with unexplored use cases such as adaptive circuits, quantum state engineering, and CV-DV hybrid systems.
