This paper discusses the potential applications of Large Language Models (LLMs), particularly the generative pre-trained transformers (GPTs), in the field of quantum computing. The author aims to explore how GPTs can contribute to the design of quantum architectures and assist in quantum computing research.

The paper starts by introducing LLMs and their success in various research areas, such as advanced chemistry, healthcare, and protein design. It then raises the question of how LLMs can be applied to emerging fields like quantum computing. The design of quantum architecture is identified as a critical aspect of quantum computing, as it defines the structure and behavior of quantum circuits. The paper suggests that GPTs can be leveraged to explore the design space of quantum architectures and generate efficient ansatz structures based on patterns and principles learned from large datasets of quantum circuits.

To implement this idea, the authors propose a Quantum GPT-Guided Architecture Search (QGAS) model. The QGAS model utilizes GPT-4 as a controller to recommend high-quality ansatz structures for Variational Quantum Algorithms (VQAs). The authors provide detailed information about the methodology and training process of the QGAS model. They also explain how human feedback and the capabilities of GPTs are incorporated into the model to improve the search for quantum circuit architectures.

The paper presents experiment results using application benchmarks, such as portfolio optimization, max-cut problem, traveling salesman problem, and molecular ground state energy estimation. The results show that the ansatz architectures generated by the QGAS model outperform existing ansatzes in some cases. The authors highlight the importance of human feedback in guiding GPT-4’s performance in quantum circuit architecture design. They also discuss the limitations of GPTs, such as their reliance on large-scale data and their inability to reason logically for complex mathematical equations.

In the discussion section, the paper explores the future potential of GPTs in the field of quantum computing. It suggests that GPTs can be further trained on quantum computing-specific datasets to gain deeper insights and assist in algorithm innovation and hardware calibration. The paper also emphasizes the need for caution in using GPTs, as they can be influenced by biased or misleading information.

Overall, the paper provides a comprehensive overview of the potential applications of LLMs, particularly GPTs, in quantum computing research. It highlights the benefits of combining human expertise with the power of advanced machine learning to accelerate progress in the design and optimization of quantum architectures. The paper also acknowledges the limitations and challenges associated with using GPTs in quantum computing and discusses possible future directions for research.
