gpu issue on qiskit - aer method , docker - cuquantum-appliance:23.10

[e-dinesh]

Hi, I'm facing an issue with my AER-State Vector simulation.

I'm using the docker image <nvcr.io/nvidia/cuquantum-appliance:23.10> and run this file [https://github.com/qiskit-community/qiskit-community-tutorials/blob/master/aer/qv_cuStateVec.ipynb]

If I use < sim = AerSimulator(method='statevector', device='GPU') >, I can see the utilization of GPUs. On the other hand, if I modify <sim = Aer.get_backend('statevector_simulator', device='GPU')> it points to cpu, NOT the GPUs.

Any idea, why is it? @sam-stanwyck
