Hardware-efficient random circuits to classify noise in a multiqubit system

JS Kim, LS Bishop, AD Córcoles, S Merkel, JA Smolin… - Physical Review A, 2021 - APS
In this work, we extend a multiqubit benchmarking technique known as the binned output
generation (BOG) in order to discriminate between coherent and incoherent noise sources …

Estimation of correlations and nonseparability in quantum channels via unitarity benchmarking

M Girling, C Cîrstoiu, D Jennings - Physical Review Research, 2022 - APS
The ability to transfer quantum information between systems is a fundamental component of
quantum technologies and leads to correlations within the global quantum process …
