Good morning, I am trying the VQLS demo and have a question on the output x. In the demo, the results of Quantum probabilities and Classical probabilities match well. But when I am trying to access x, I found that it is not accurate enough: Classical result: x = [0.25253814 0.25253814 0.35355339 …

Hey @Dobby and welcome to the forum! I believe the differences in the vectors you provide are due to the normalization. For example, take the classical (unnormalized) result x and find x / np.linalg.norm(x). The result will be much closer to the quantum value you provide. More generally, the quant…

Hi @sajal. Welcome to the Forum!

I see that you asked several questions related to VQLS. Were all of them answered in this thread?

Or do you have an additional question related to this thread and this other one?
