Efficient Sampling of Noisy Shallow Circuits Via Monitored Unraveling
We introduce a classical algorithm for sampling the output of shallow, noisy random circuits on two-dimensional qubit arrays. The algorithm builds on the recently proposed “space-evolving block decimation” (SEBD) [Napp et al, Phys. Rev. X 12, 021021 (2022)] and extends it to the case of noisy circui...
