class Reset(Operation):
    """Reset operation.

    Quantum operation that resets the status of one qubit to the :math:`\\ket{0}` state.

    This operation is non-reversible.

    Examples:
        Adding Reset operation to the Circuit (The args can be: range, list, tuple, set or int)

        >>> from mimiqcircuits import *
        >>> c= Circuit()
        >>> c.push(Reset(), 0)
