Abstract
Systems and techniques that facilitate improved single-shot error mitigation for Clifford circuits are provided. For a Clifford circuit, various embodiments described herein can facilitate two-sided or one-sided Pauli checks. In various aspects, left-side Pauli operators of two-sided Pauli checks can be selected randomly without replacement, and right-side Pauli operators of two-sided Pauli checks can be identified via commutation identities respectively relating the Clifford circuit to the left-side Pauli operators. In various instances, Pauli operators of one-sided Pauli checks can be selected via commutation identities respectively relating the Clifford circuit to Z-type Paulis selected randomly without replacement. For either two-sided or one-sided Pauli checks, various embodiments described herein can involve implementation of interleaved SWAP gates, which can allow such two-sided or one-sided Pauli checks to be performed on linear nearest neighbor coupling topologies.
