Not compatible with latest version of Qiskit?

[anthonysmaldone]

I was trying to run the state preparation example on the front page of the github, but I got the following error:

<ipython-input-2-4b963d01b3d2>:3: DeprecationWarning: The qiskit.extensions module is deprecated since Qiskit 0.46.0. It will be removed in the Qiskit 1.0 release.
  from qiskit.extensions.quantum_initializer import Initialize  # Assuming you're using Qiskit's Initialize for state preparation

Is there a certain version of Qiskit that is compatible?

Hello, @anthonysmaldone. Thank you very much for your contribution. The compatibility issue with qiskit version 0.46.0 has been fixed on PR #172.
