@BrunoLiegiBastonLiegi BrunoLiegiBastonLiegi commented Mar 8, 2024

This PR removes the qibo.models.Circuit._Queue.append() method that was overloading the list.append(). The generation of the moments and the calculation of the number of measurements in the circuit is therefore delayed to when it's actually needed. This was mainly motivated by the random_clifford function that appends a lot of gates to the circuit, but I believe it is in general useful for speeding up all the functions that make heavily use of the Circuit.add() method, even though the difference in most cases is probably negligible.

Thanks @stavros11, made them properties once again.

@property

moments = [self.nqubits * [None]]
moment_index = self.nqubits * [0]

Before, users had access to moment_index and now they don't. I don't know if this is the intended behaviour or not.

return len([1 for gate in self if isinstance(gate, gates.M)])
