If $|0\rangle$ becomes $|f_0(x)|^2$ and $|1\rangle$ becomes $|f_1(x)|^2$ then the state $\sqrt |11\rangle $$ These are variables which are allowed to be in the states $|0\rangle,\,|1\rangle,$ and any quantum superposition of them $\alpha|0\rangle \beta|1\rangle$ where $\alpha,\beta\in\mathbb C$ and $|\alpha|^2 |\beta|^2 = 1.$ All of those superpositions are "non-classical": there are experiments you can do on them which display strange outcomes. Let me give you one example, qubits (quantum bits). Quantum entanglement emerges naturally from the "only obvious way to do things" at the wavefunction level (distribute a wavefunction over all possibilities of two subsystems), and describes the fact that the general state of these systems cannot be "decoupled" into a pair of states for each of the subsystems. You have a wrong understanding of quantum entanglement.
