Abstract
Systems, computer-implemented methods, and/or computer program products to facilitate noise characterization of a two-qubit unitary are provided. A system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise an execution component that executes a two-qubit quantum circuit comprising a preparation of an initial state for a two-qubit Pauli operator and an application of one or more circuit layers, wherein each circuit layer comprises an application of a pair of random gates each selected from I, X, Y or Z, application of the two-qubit unitary having a rotation angle modified to have a 50% probability of being each of positive and negative, and another application of the first random gate and the second random gate. A fitting component employs curve fitting of an expectation value resulting from the execution.
