| Abstract: | This article discusses the complete separability and partial separability ofthe mixed states of quantum network of three nodes by means of thecriterion of entanglement in terms of the covariance correlation tensor inquantum network theory. |
| Keywords: | covariance correlation tensor in quantum network theory criterion of entanglement mixed state |
