Foundations of Q-physics

Research output: Contribution to journalArticle


We can see that multiplying the state vector by a complex phase factor yields the same density matrix, i.e., the same q-state. Hence the phase of the state vector can be deliberately altered, still the same pure q-state is obtained. In the conservative q-theory, contrary to the classical theory, not even the pure state is interpreted on a single system but on the statistical ensemble of identical systems
