Squashing everything into one commit after we finish review. Thus I leave the generic 'Fix comments & typos' as it is for now. |
Add a test which can serve as example including the modifications to support the `reset` keyword in the import of QASM files in the PLY based lexer/parser.

There was a problem hiding this comment.
Should there be some sort of check here to ensure the reset is applied on a qubit that is actually defined in the quantum register? E.g. should some error be raised when trying to parse the following QASM program?
OPENQASM 2.0;
include "qelib1.inc";
qreg q[1];
reset q[2];

Note / 20240914:
After further inspection, I wonder why resets are implemented quite different to regular gates, despite following a somewhat similar terminology (
cirq.Rorcirq.reset) however, returning a ResetChannel. It appears to me that the reset is more similar to a measurement than compared to say a Hadamard gate.
