Tolerant testing of stabilizer states with a polynomial gap via a generalized uncertainty relation

Quantum Physics 2025-08-14 v2

Abstract

We prove a conjecture of Arunachalam & Dutt ([AD24]) on the existence of a tolerant stabilizer testing algorithm, and achieve an exponential improvement in the parameters of the tester. Key to our argument is a generalized uncertainty relation for sets of Pauli operators, based on the Lovasz theta function.
