A new class of randomized benchmarking protocols: theory and expiriment

 · Invited

Abstract

In this talk I will discuss a new class of randomized benchmarking protocols called character randomized benchmarking. Character randomized benchmarking allows one to extend standard randomized benchmarking in a principled manner to groups beyond the Clifford group. I will discuss the theory of character randomized benchmarking, some example protocols such as benchmarking a T gate and performing two qubit interleaved randomized benchmarking using only single qubit gates as reference, and I will also precent some recent experimental implementations of character randomized benchmarking.
