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 [59].

Workflow of the PEA technique in Mitiq, detailed in the What happens when I use PEA? section.

Below you can find sections of the documentation that address the following questions:

• How do I use PEA?
• When should I use PEA?
• What additional options are available in PEA?
• What happens when I use PEA?
• What is the theory behind PEA?
