Transpiler optimization_method="zxpass" gives wrong result

[BankNatchapol]

Environment

• Qiskit version: 1.1.0
• Python version: 3.10.12
• Operating system: Google Colab

What is happening?

Circuits after Transpilation should give similar result, but not.

How can we reproduce the issue?

from qiskit.quantum_info import Statevector
from qiskit.compiler import transpile

with open('acircuit.qpy', 'rb') as handle:
    qc = qpy.load(handle)
wo = transpile(qc, basis_gates=['cz', 'swap', 'cx', 'tdg', 's', 'sdg', 'h', 'rz'], optimization_level=1)[0]
w = transpile(wo, basis_gates=['cz', 'swap', 'cx', 'tdg', 's', 'sdg', 'h', 'rz'], optimization_method="zxpass")

print(Statevector(wo))
print(Statevector(w))

ill attach acircuit.qpy acircuit.zip

What should happen?

the statevector should be the same.

Any suggestions?

If it's correct, please guide me how to make the statevector output to be the same. Thank you in advance.

The state vectors produced by your program appear to be equivalent.

What's the output of the following for you?

print(Statevector(wo).equiv(Statevector(w)))

This results in the output True for me.

@BankNatchapol Can this issue be closed?

I'm going to close this issue as your repro case works perfectly fine for me. Please let me know if there's anything that's unclear or I could help you with.
