Dirac’s misconception that classical and quantum superpositions are different because absolute phase is quantum physically meaningless is, even today, seemingly blindly believed by many physicists. However, there is no such difference because, time translation symmetry means absolute time and, thus, absolute phase are classical physically meaningless, too. As a qubit can be a polarization division multiplexed (PDM) quadrature amplitude modulated (QAM) symbol of light, its state has direct correspondence with polarization state of classical light. Even more intuitively, the state may be represented by two-dimensional mechanical oscillations of a pendulum, which enables intuitive understanding of not-really-quantum superpositioned states of a qubit even by elementary school pupils.
