# Cycle Benchmarking (CB)¶

Cycle benchmarkinga (CB) is a breakthrough new capability to efficiently estimate the holistic and full impact of all local and global error rates from all relevant error mechanisms including error correlations and cross-talk (see [3]) for any parallel set of quantum operations over an $$n$$-qubit quantum processor. CB is a completely scalable protocol that also enables Noise Reconstruction (NR) for developing a detailed understanding of the leading error mechanisms that limit system performance. A simplified version of CB for Clifford gates is illustrated below.
