As far as wave function is the characteristic function of the probability (density) distribution for all possible values of a certain quantity to be measured, the definition of quantity in quantum mechanics means any unitary change of the probability (density) distribution. It can be represented as a particular case of “unitary” qubits. The converse interpretation of any qubits as referring to a certain physical quantity implies its generalization to nonHermitian operators, thus neither unitary, nor conserving energy. Their physical sense, speaking loosely, consists in exchanging temporal moments therefore being implemented out of the spacetime “screen”. “Dark matter” and “dark energy” can be explained by the same generalization of “quantity” to nonHermitian operators only secondarily projected on the pseudoRiemannian spacetime “screen” of general relativity according to Einstein's “Mach’s principle” and his field equation. Keyphrases: Quality, quantity, quantum information, qubit Hilbert space, spacetime
