Performance and error modeling of Deutsch's algorithm in IBM Q

The performance of quantum computers today can be studied by analyzing the eect of errors in the result of simple quantum algorithms. The modeling and char- acterization of these errors is relevant to correct them, for example, with quantum correcting codes. In this article we characterize the error of the ve qubits quantum computer ibmqx4 (IBM Q), using a Deutsch algorithm and modeling the error by Generalized Amplitude Damping (GAD) and a unitary misalignment operation.
