A Bayesian-network-based quantum procedure for failure risk analysis.

In this paper, we propose a procedure for creating a model of the system on a quantum computer using a restricted representation of Bayesian networks. We present examples of this implementation on sample models using Qiskit and test them using both quantum simulators and IBM Quantum hardware. The results show a correlation in the precision of the results when considering the number of Monte Carlo iterations alongside the sum of shots in a single quantum circuit execution.engjournal articlehttps://link.springer.com/article/10.1140/epjqt/s40507-023-00171-4https://epjqt.epj.org/articles/epjqt/abs/2023/01/40507_2023_Article_171/40507_2023_Article_171.htmlopen accessBayesian networkQuantum computingRisk analysisResilience analysisReliability analysisInformática (Informática)1203 Ciencia de Los Ordenadores
