Summary

Manuel Rudolph presents Pauli propagation (PP), a classical simulation framework for quantum systems, at QTML 2025. He explains that PP approximates the evolution of quantum operators via truncated Pauli path integrals, offering an alternative to tensor network methods. The talk covers the algorithmic formulation, theoretical guarantees, and practical implementation in the open-source library PauliPropagation.jl. Rudolph highlights that PP is particularly efficient for expectation values and noisy circuits, and can be combined with quantum hardware in hybrid approaches. He discusses limitations related to ‘magic’ and deep circuits, but shows applications in VQE and dynamics. The presentation includes results on noise-free random circuits and noisy systems, and mentions future work on different bases and GPU acceleration.
