    Quantum Bogo Sort is a theoretical sorting algorithm that uses quantum
    mechanics to sort the elements. It is not practically feasible and is
    included here for humor.

    :param arr: list[int] - The list of numbers to sort.
    :return: list[int] - The sorted list, humorously assumed to be
    instantly sorted using quantum superposition.

    Example:
    >>> quantum_bogo_sort([2, 1, 4, 3])
    [1, 2, 3, 4]

    >>> quantum_bogo_sort([10, -1, 0])
    [-1, 0, 10]

    >>> quantum_bogo_sort([5])
    [5]

    >>> quantum_bogo_sort([])
    []
