Matrix Tensor Product Approach to the Equivalence of Multipartite States under Local Unitary Transformations

by X. H. Gao, S. Alberverio, S. M. Fei, Z. X. Wang , 2006
"... The equivalence of multipartite quantum mixed states under local unitary transformations is studied. A criterion for the equivalence of non-degenerate mixed multipartite quantum states under local unitary transformations is presented. PACS numbers: 03.67.-a, 02.20.Hj, 03.65.-w Quantum entangled stat ..."

states are playing fundmental roles in quantum information processing such as quantum computation, quantum teleportation, dense coding, quantum cryptographic schemes quantum error correction, entanglement swapping, and remote state preparation (RSP) etc.. However the theory of quantum entanglement

Spotlight on Teachers

by James Lewis
"... This article discusses three recent reports that share two themes: good teachers matter and the education of mathematics teachers has special importance. Before It’s Too Late can be viewed as a political answer to an issue of national importance. Educating Teachers of Science, Mathematics, and Techn ..."

, and Technology provides a review of research that makes the case for the importance of a wellprepared teacher and then advocates a fundmental restructuring of teacher preparation and professional development. Finally, The Mathematical Education of Teachers offers a discipline-based response to the question
