我们然后在VQE运行时设置它,就有QuantumInstance可以使用了。 algorithm_globals.random_seed=seedqi=QuantumInstance(Aer.get_backend('aer_simulator_statevector'),seed_transpiler=seed,seed_simulator=seed)ansatz=TwoLocal(rotation_block

I have addressed the previous comment and also updated all occurrences of algorithm_globals. See df0137c for more details on the latter. Member woodsp-ibm commented Sep 14, 2023 • edited One other thing - this also uses qiskit.utils validation eg like this in places from qiskit.utils....
