Reexamination determinant-based separability qubits
2010/10/29
It was shown in [Augusiak et al.,\;Phys. Rev. A \textbf{77}, 030301(R) (2008)] that discrimination between entanglement and separability in a two qubit state can be achieved by a measurement of a sin...
Separability and Fourier representations of density matrices
Separability Fourier representations density matrices
2010/10/13
Using the finite Fourier transform, we introduce a generalization of Pauli-spin matrices for ddimensional spaces, and the resulting set of unitary matrices S (d) is a basis for d × d matrices. If N = ...
