Multi-partite Quantum Entanglement  

Lee, Hyuk-Jae (Department of Physics, Kookmin University)
Abstract
We present a method describing the quantum entanglement. We knows the criterion which can determine entanglement in a bipartite system. It is difficult in mixed states. Even though the entanglement criterion for multipartite systems is difficult, we offer a criterion for multiqubits and discuss entanglement of the mixed state.
Keywords
multi-partite; quantum entanglement; entanglement criterion; mixed state;
