| Title: | The automorphism group of separable states in quantum information theory | Authors: | Friedland, S Li, CK Poon, YT Sze, NS |
Issue Date: | 2011 | Source: | Journal of mathematical physics, 2011, v. 52, no. 4, 42203 | Abstract: | We show that the linear group of automorphism of Hermitian matrices which preserves the set of separable states is generated by natural automorphisms: change of an orthonormal basis in each tensor factor, partial transpose in each tensor factor, and interchanging two tensor factors of the same dimension. We apply our results to the preservers of the product numerical range. | Publisher: | Amer Inst Physics | Journal: | Journal of Mathematical Physics | DOI: | 10.1063/1.3578015 |
