Abstract
One example aspect of the present disclosure is directed to a method for characterizing a multi-qubit logic gate operating on a pair of qubits. The method includes iteratively performing, via a multi-qubit quantum circuit, a set of serial operations on the pair of qubits. The multi-qubit quantum circuit includes the multi-qubit logic gate, a first single-qubit logic gate operating on the first qubit, and a second single-qubit logic gate operating on the second qubit. After iteratively performing the set of serial operations on the pair of qubits, a first quantum state of the first qubit and a second quantum state of the second qubit are measured. A first set of expectation values for the first qubit and a second set of expectation values for the second qubit are determined. A value for a first parameter of a set of parameters of the multi-qubit logic gate is determined.
