摘要: We discuss the problem of determining whether state several quantum mechanical subsystems is entangled. As in previous work on two we introduce a procedure for checking separability that based finding extensions with appropriate properties and may be implemented as semidefinite program. The main result this to show there series tests kind such if multiparty entangled will eventually detected by one tests. also provides means constructing entanglement witnesses could principle measured order demonstrate
