Description:
Author(s): Omar Gamel We represent a two-qubit density matrix in the basis of Pauli matrix tensor products, with the coefficients constituting a Bloch matrix, analogous to the single qubit Bloch vector. We find the quantum state positivity requirements on the Bloch matrix components, leading to three important inequaliti… [Phys. Rev. A 93, 062320] Published Mon Jun 20, 2016
