Replace _compat.cached_property with functools.cached_property #6395
Closed
Description
Description of the issue
cirq uses an internal version of cached_property defined here to support earlier versions of Python.
Cirq/cirq-core/cirq/_compat.py
Lines 64 to 67 in d33b1a7
As of #6167 we require Python 3.9 which is guaranteed to have functools.cached_property.
We can therefore replace all instances of _compat.cached_property with functools.cached_property and remove the cached_property definition from the _compat.py.
Cirq version
1.4.0 at d33b1a7
