Abstract

Lamata et al. have presented an entanglement classification of four qubits under stochastic local operation and classical communication (SLOCC) based on an inductive approach [Phys. Rev. A 75, 022318 (2007)]. While it works well for three qubits, we show that some of the families for four qubits have overlaps and hence this approach is not valid for entanglement classification of four or more qubits under SLOCC.
