SLOCC invariant and semi-invariants for SLOCC classification of four-qubits
arXiv:quant-ph/0701032 · doi:10.1103/PhysRevA.76.052311
Abstract
We show there are at least 28 distinct true SLOCC entanglement classes for four-qubits by means of SLOCC invariant and semi-invariants and derive the number of the degenerated SLOCC classes for n-qubits.
