I am running a VQE over the H2 molecule on ibmq_quito and I set a callback function to save all jobs id's of all iterations. When I check the penultimate job (and the previous ones), I have 2 circuits or experiments (one for Z basis and one for X basis). But when I check the last job, I just obtain one circuit. Does anyone know why on the last job of the VQE I have one circuit while I still have to measure in different basis to get the expectation value of the energy? Thank you very much in advance!
