Abstract:

This article presents the current capabilities of measuring the accuracy of selected IBM Q-class quantum architectures for specific stages and tasks of the recommendation process in hybrid classicalquantum recommender systems. A comparison of the implementation of complex multi-qubit circuits in a quantum simulator versus an implementation on a real quantum computer is discussed to demonstrate the measurement accuracy of currently available quantum architectures and the error rate relative to near-ideal circuit simulation. Significant aspects of error generation are discussed, and the underlying causes are identified.
