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