# Probabilistic Error Amplification

Probabilistic error amplification (PEA) is an error mitigation technique in which
noise-amplified circuits are sampled probabilistically at different noise levels.
Expectation values are estimated for each noise level and then extrapolated to the
zero-noise limit {cite}`Kim_2023_Nature`.
