The demonstrator shows the time evolution of a small network with failures. Users can choose to analyse systems with either one, two or three nodes, where always one node is exhibiting a defect state. For a given number of time steps results may be loaded, which show how the population of each quantum states evolves. Depending on availability, new results can be generated on IBM backends.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In this demonstrator, we perform hybrid, Grover based optimization to find the single network parameter change leading to the largest reduction of the critical failure probability in a cascading network. The implemented Grover search algorithm utilizes an imperfect, Quantum Amplitude Estimation (QAE) based oracle.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
