Dynamics of initially entangled open quantum systems
Thomas F. Jordan, Anil Shaji, E. C. G. Sudarshan
Linear maps of matrices describing evolution of density matrices for a quantum system initially entangled with another are identified and found to be not always completely positive…

Affine maps of density matrices
Thomas F. Jordan
For quantum systems described by finite matrices, linear and affine maps of matrices are shown to provide equivalent descriptions of evolution of density matrices for a subsystem c…
