Abstract

The pure quantum state of two quibits (i.e. two- level quantum mechanical systems such as photons), is called entangled if it is impossible to factorize into a tensor product of states for the separate systems, |ψ〉 ≠ |ψ1〉⊗|ψ2〉. A mixed state is entangled if it is impossible to represent the density operator as a statistical mixture of factorable pure states.
