Classicality in discrete Wigner functions
Cecilia Cormick, Ernesto F. Galvao, Daniel Gottesman +2
Gibbons et al. [Phys. Rev. A 70, 062101(2004)] have recently defined a class of discrete Wigner functions W to represent quantum states in a Hilbert space with finite dimension. We…
Mutually Unbiased Bases, Generalized Spin Matrices and Separability
Arthur O. Pittenger, Morton H. Rubin
A collection of orthonormal bases for a complex dXd Hilbert space is called mutually unbiased (MUB) if for any two vectors v and w from different bases the square of the inner prod…
Unextendible product bases and the construction of inseparable states
Arthur O. Pittenger
Let H[N] denote the tensor product of n finite dimensional Hilbert spaces H(r). A state |phi> of H[N] is separable if |phi> is the tensor product of states in the respective produc…
Convexity and the Separability Problem of Quantum Mechanical Density Matrices
Arthur O. Pittenger, Morton H. Rubin
A finite dimensional quantum mechanical system is modeled by a density rho, a trace one, positive semi-definite matrix on a suitable tensor product space H[N] . For the system to d…
