Project

Implementing Zero Noise Extrapolation without folding

Objective

The two primary requirements in the zero noise extrapolation (ZNE) protocol are the noise factors and the extrapolator. However, the same noise factors does not provide similar accuracy for circuits of different depth and width. And there is no obvious method to decide the optimal noise factors for a given circuit. In this project we propose a method to perform zero noise extrapolation without folding. In this method the effect of folding is obtained via transpilation, thus eliminating the requirement for finding optimal noise factors. Moreover, transpilation itself can also be used to decide the suitable extrapolator for the given circuit. Hence this method makes using ZNE seamless for users with little or no experience.

Outcome

We expect a publication and a GitHub repository with the implementation of this method as part of this project.
