Outline

This paper analyzes transfer learning of variational quantum circuits (VQCs). Starting from a pre-trained VQC in an existing domain, we present a framework for computing the transfer of a 1-parameter unitary subset of the required domain to a new domain. We establish a formal framework for investigating the adaptability and performance of VQCs through loss boundary analysis, and we observe knowledge transfer in VQCs and provide a heuristic interpretation of their mechanisms. We derive an analytical fine-tuning method to achieve optimal transfer for similar domain adaptation.

Takeaways, Limitations

Takeaways: Provides theoretical understanding of the transfer learning mechanism of VQC, and proposes an efficient fine-tuning method. It can contribute to improving adaptability across similar domains.
Limitations: The proposed analytical fine-tuning method may be limited to similar domains. Further research on the transfer learning performance across different domains is needed. There is a lack of experimental verification using real quantum computers. Further review on the rigor of the loss boundary analysis may be needed.
