摘要：
We present a description of the entanglement for a multiqubit by using the quantum correlation tensors that rely on the expectation values of the Pauli operators for a multiqubit state. Our description explains not only the total entanglement of the system but also the partial entanglement in subsystems. It shows that we have to consider the subsystem entanglement in order to obtain the full description for multiqubit entanglement. Furthermore, we offer an extension of the entanglement to multiqudits.
