There was a problem hiding this comment.
raise ValueError('Intermediate measurements on three or more qubits with a custom key are not supported')if this line is too long you can break it into two string literals
raise ValueError('Intermediate measurements on three or more qubits '
'with a custom key are not supported')

router mishandling mid-circuit measurements #issue6293
Description of the issue
cirq.RouteCQCcommutes gates in undefined ways due to intermediate measurements with 3 or more qubits not being handled correctly.This PR aims to fix this issue by:
Breaking intermediate measurements on 3+ qubits into single qubit measurements if the result isn't stored (i.e. key is None) else a
ValueErroris raised.Next Steps
Check if it's possible to create a ClassicallyControlledOperation controlled by the result of a multiqubit measurement
From looking at the documentation it seems to be possible. Will stop here until there is a need to support this case.
