Entanglement for All Quantum States
de la Torre, A. C.; Goyeneche, D.; Leitao, L.
European Journal of Physics, v31 n2 p325-332 Mar 2010
It is shown that a state that is factorizable in the Hilbert space corresponding to some choice of degrees of freedom becomes entangled for a different choice of degrees of freedom. Therefore, entanglement is not a special case but is ubiquitous in quantum systems. Simple examples are calculated and a general proof is provided. The physical relevance of the change of tensor product structure is mentioned.
