Geometry and Entanglement of Two-Qubit States in the Quantum Probabilistic Representation

Geometry and Entanglement of Two-Qubit States in the Quantum Probabilistic Representation

A new geometric representation of qubit and qutrit states based on probability simplexes is used to describe the separability and entanglement properties of density matrices of two qubits. The Peres–Horodecki positive partial transpose (ppt) -criterion and the concurrence inequalities are...
