New technique: Probabilistic Error Amplification #2343

Open Misty-W opened 2 months ago

Misty-W commented 2 months ago

Issue Description

Investigate Probabilisitic Error Amplification as a noise scaling technique to be applied in conjunction with Zero Noise Extrapolation. In this technique, error amplification (gate) sequences are applied probabilistically to scale the noise level of the computation.

Proposed Solution

The scope of this issue is to investigate the technique and provide an outline for an RFC.

Just adding here that the NEPEC formalism could be used to implement PEA. Basically expanding PEC representations to accommodate noise + use ZNE Factories for extrapolation. There is some relevant code in the research repository wrt to the NEPEC paper.
