Qubit portraits of qudit states and quantum correlations

Cosmo Lupo, V I Man'ko, G Marmo

The machinery of qubit-portraits of qudit states, recently presented, is consider here in more details in order to characterize the presence of quantum correlations in bipartite qudit states. In the tomographic representation of quantum mechanics, Bell-like inequalities are interpreted as peculiar properties of a family of classical joint probability distributions which describe the quantum state of two qudits. By means of the qubit-portraits machinery a semigroup of stochastic matrices can be associated to a given quantum state. The violation of the CHSH inequalities is discussed in this framework with some examples, we found that quantum correlations in qutrit isotropic states can be detected by the suggested method while it cannot in the case of qutrit Werner states.

Three Dimensional Visualization of Qutrit States

Vinod K. Mishra

The qutrit comes next in complexity after qubit as a resource for quantum information processing. The qubit density matrix can be easily visualized using Bloch sphere representation of its states. In contrast, this simplicity is in general unavailable for the 8-dimensional state space of a qutrit. In this work a new way to visualize them in a 3-dimensional Cartesian space is presented and compared with earlier similar efforts.
