device.run in tutorial outdated

[tcochran-quera]

In understanding how to use PyQrack to simulate a squin kernel I turned to the QFT example, which has the following:

Finally, we will run the main function on the PyQrack backend and print the quantum register to see the final state of the qubits after applying the QFT circuit.

device = PyQrack()
qreg = device.run(main)
print(qreg)

But, this seems to only return if each qubit is active or not (not it's quantum state as the text suggests).

@david-pl suggested we should update this to us the StackMemorySimulator.
