Say I have multiple backends, I need a score to determine how well a backend is suitable for that particular circuit, I have it’s noise model too, I tried transpiling the circuit and calculating noise estimate through th…

I’m working with very large matrices for QUBO problems, and I’m currently using QBsolv from D-Wave. However, given that Qbsolv is being discontinued, I identified that D-wave has 2 solutions for this type of problem: Lea…
