Abstract: AI advancements over the past few years have had an unprecedented and revolutionary impact across everyday application areas. Its significance also extends to technical challenges within science and engineering, including the nascent field of quantum computing (QC). The counterintuitive nature and high-dimensional mathematics of QC make it a prime candidate for AI's data-driven learning capabilities, and in fact, many of QC's biggest scaling challenges may ultimately rest on developments in AI. However, bringing leading techniques from AI to QC requires drawing on disparate expertise from arguably two of the most advanced and esoteric areas of computer science. Here we aim to encourage this cross-pollination by reviewing how state-of-the-art AI techniques are already advancing challenges across the hardware and software stack needed to develop useful QC - from device design to applications. We then close by examining its future opportunities and obstacles in this space.

Context and Significance

Quantum computing has the potential to revolutionize numerous fields, notably intractable problems in chemical simulation and optimization. However, the realization of practical, fault-tolerant quantum computers requires overcoming significant hurdles, particularly in transitioning current noisy intermediate-scale quantum (NISQ) devices to fault-tolerant quantum computing (FTQC) frameworks. These challenges include engineering robust quantum error correction (QEC) codes, enhancing qubit architectures, and accelerating both hardware and software aspects of QC.

AI's data-driven capabilities provide a robust toolkit for these challenges, making it an indispensable asset in developing quantum computing solutions. By harnessing ML and deep learning methodologies, AI facilitates the automation and optimization processes critical to QC advancement.

AI in Quantum Computing: Key Applications

1. Quantum Hardware Design and Optimization: AI techniques, including ML algorithms and neural networks, are employed to characterize and enhance quantum devices. This involves optimizing control pulses and designing quantum hardware that minimizes noise and maximizes performance.
2. Circuit Synthesis and Algorithm Design: AI-driven methods like reinforcement learning can automate the circuit synthesis process, generating more efficient quantum circuits. These methodologies also aid in the discovery of novel quantum algorithms, potentially expanding the toolkit of quantum computation.
3. Quantum Error Correction and Decoding: AI models, such as neural networks and graph-based techniques, are being explored to improve the scalability and efficiency of QEC decoders. These AI-enhanced decoders adapt more effectively to noise correlations and variability, crucial for maintaining error suppression below critical thresholds.
4. Simulation and Data Generation: Simulating quantum systems efficiently is crucial as large quantum datasets are scarce. AI aids in generating high-fidelity synthetic data necessary for training more capable models, thereby accelerating quantum development.
5. Quantum State Preparation and Measurement Optimization: AI algorithms optimize quantum state preparation, reducing resource overhead significantly. They also enhance the precision and efficiency of quantum measurements, crucial for extracting accurate results from quantum computations.

Implications and Future Directions

The application of AI to QC not only aids in overcoming current technological barriers but also opens avenues for discovering new quantum algorithms and applications previously unimagined. The synergy between these fields can lead to accelerated development timelines and improved performance of quantum systems, potentially ushering in a new era of scientific and industrial capabilities.

The paper argues for the creation of hybrid quantum-classical infrastructure that leverages AI's processing power in concert with quantum processors, aiming for an architecture that supports large-scale, useful quantum computation.

Moreover, continuous advancements in AI, such as diffusion models, foundational AI models, and reinforcement learning, hold promise for further enhancing QC's computational prowess. The pursuit of these technologies is not merely an academic exercise but a strategic investment in the future of computation and problem-solving.

In summary, this exposition of AI's role in quantum computing underscores a pivotal evolution in computational paradigms. This intersection is poised to redefine the boundaries of what is computationally feasible, necessitating ongoing research and innovation at the nexus of these transformative technologies.
