Tomographic and Improved Subadditivity Conditions for Two Qubits and a Qudit with j = 3/2

Tomographic and Improved Subadditivity Conditions for Two Qubits and a Qudit with j = 3/2

We obtain a new entropic inequality for quantum and tomographic Shannon information for systems of two qubits. We derive the inequality relating quantum information and spin-tomographic information for particles with spin j = 3/2. We recommend the method for obtaining new entropic and information in...

Zusammenfassung:We obtain a new entropic inequality for quantum and tomographic Shannon information for systems of two qubits. We derive the inequality relating quantum information and spin-tomographic information for particles with spin j = 3/2. We recommend the method for obtaining new entropic and information inequalities for composite systems of qudits, as well as for one qudit.
