Quantum Computers and Classical AI Combine for Better Results in Complex Problem-Solving

The intersection of noisy quantum computers and classical deep learning has led to a breakthrough in quantum error mitigation. Researchers have discovered that by combining the computational power of noisy quantum computers with scalable classical convolutional neural networks (CNNs), they can achieve higher accuracy than either approach alone. This synergy enables the accurate prediction of exact expectation values of parameterized quantum circuits, representing the dynamics of quantum Ising models. The potential benefits of this combination are vast, promising to revolutionize the field of quantum computing and enable more efficient solutions for complex computational problems.

Can Noisy Quantum Computers and Classical Deep Learning Combine for Better Results?

Synergy between Noisy Quantum Computers and Scalable Classical Deeplearning

The article explores the potential of combining the computational power of noisy quantum computers with that of classical scalable convolutional neural networks (CNNs). The goal is to accurately predict exact expectation values of parameterized quantum circuits representing the Trotter-decomposed dynamics of quantum Ising models. By incorporating simulated noisy expectation values alongside circuit structure information, the CNNs effectively capture the underlying relationships between circuit architecture and output behavior, enabling transfer learning and predictions for circuits with more qubits than those included in the training set.

The synergy between quantum and classical computational tools leads to higher accuracy compared with quantum-only or classical-only approaches. The authors demonstrate that by tuning the noise strength, they can explore the crossover from a computationally powerful classical CNN assisted by noisy quantum data towards rather precise quantum computations further error-mitigated via classical deeplearning.

Quantum Computers Promise but are Limited by Hardware Errors

Quantum computers promise to solve computational problems that are intractable on classical machines. However, efforts to exploit the full power of quantum computing are currently limited by hardware errors. To address this issue, quantum error mitigation techniques have been developed to minimize noise and obtain potentially useful results.

While error mitigation methods reduce noise in expectation values of observables, they may display limited accuracy or suffer from prohibitive sampling overheads. In this scenario, classical machine learning emerges as a suitable tool for post-processing noisy quantum measurements, achieving accurate expectation values at potentially lower computational cost.
