    Quantum Mechanics Entangled States

    Your definition of entanglement is a bit off. A state is entangled if it cannot be written in terms of a product of two (or more if your looking at many qubits) single qubit states. i.e. if Alice and Bob share two qubits in a general state: \vert\psi_{AB}\rangle=a\vert 00\rangle+b\vert...
