Quantum gate set tomography is a robust and powerful method for self-consistently characterizing an entire set of quantum logic gates on a black-box quantum device. This method arose from the observation that [[ | Quantum gate set tomography is a robust and powerful method for self-consistently characterizing an entire set of quantum logic gates on a black-box quantum device. This method arose from the observation that [[Quantum Process tomography]] is inaccurate in the presence of state preparation and measurement errors. This procedure estimates the complete process matrices of Pauli transfer matrices for the gate set based on experimental data. | ||

[[ | [[Quantum state tomography]] and [[Quantum process tomography]] assume that the initial states and measurements are known. But if the [[state preparation and measurement]] (SPAM) gates are faulty then the estimates provided using these techniques are faulty as well. Quantum gate set tomography solves this problem by including the SPAM gates self-consistently in the gate set to be estimated. | ||
