Exact and practical pattern matching for quantum circuit optimization

Qiskit/qiskit-terra 11 Sep 2019

An important building block for many quantum circuit optimization techniques is pattern matching, where given a large and a small quantum circuit, we are interested in finding all maximal matches of the small circuit, called pattern, in the large circuit, considering pairwise commutation of quantum gates.
