Abstract: It is emphasized the fact, which is seldom discussed in quantum mechanics, that the quantum state of a given system of one or more, but a finite number, microscopic particles is unobservable by finite measurements,  and based on this fact, the concepts of the “qubit,” Bell states, quantum entanglement, and quantum teleportation are discussed. It is proven that the current mathematical proof for the creation of the Bell singlet state with a 50/50 beam splitter is unreasonable .
