          Abstract

          Construction of non-isomorphic cospectral graphs is a nontrivial problem in spectral graph theory specially for large graphs. In this paper, we establish that graph theoretical partial transpose of a graph is a potential tool to create non-isomorphic cospectral graphs by considering a graph as a clustered graph.

          Separability Criterion for Density Matrices

          Asher Peres (1996)
          A quantum system consisting of two subsystems is separable if its density matrix can be written as ρ=∑AwAρ′A⊗ρ″A, where ρ′A and ρ″A are density matrices for the two subsytems. In this Letter, it is shown that a necessary condition for separability is that a matrix, obtained by partial transposition of ρ, has only non-negative eigenvalues. This criterion is stronger than Bell's inequality.
