How to reproduce the issue Run pytest in cirq-core/, using Python 3.11.2.

Cirq version 1.1.0

[tanujkhattar]

I think this is important to fix soon, should be relatively straightforward and would unblock support for Python 3.11

cc @navaro1 - In case you are looking for important things to work upon. I'll get back to your serialization PR soon; that one was more ambiguous in terms of requirements so it's taking longer than usual.

@tanujkhattar, feel free to assign to me.

@tanujkhattar, FYI: https://github.com/quantumlib/Cirq/pull/6181

[tanujkhattar]

This is now fixed and Python 3.11 tests are added to CI after https://github.com/quantumlib/Cirq/pull/6191
