    • Entanglement and separability of graph Laplacian quantum states 

      Joshi, Anoopa; Singh, Parvinder; Kumar, Atul (Springer, 2022-04-07)
      In this article, we study the entanglement properties of multi-qubit quantum states using a graph-theoretic approach. For this, we define entanglement and separability for m-qubit quantum states associated with a weighted ...
