Correlating Capability of Non Local HamiltonianAuthors: Sourav Chatterjee, S.K.Sazim,Indranil Chakrabarty,Harjinder Singh Conference: INTERNATIONAL CONFERENCE ON QUANTUM INFORMATION AND QUANTUM COMPUTING (ICQIQC 2013) Date: 2013-01-07 Report no: IIIT/TR/2013/30 AbstractIn this work we specify various parameters like 1) local quantumness 2) entangling capability 3) classical randomness and give a canonical rep- representation of two qubit mixed quantum states based on them. Here we investigate the correlating capability of a non local Hamiltonian acting on general two qubit states in context of these parameters. In particular we address the questions like: 1.What is the rate of change of the standard measures of correlation like Entanglement (E) and Discord (D). 2.How these measures get affected by the change of the parameters. 3.For what choice of initial parameters, these rates of change of correlation like dE/dt ; dD/dt are maximum. 4.We study its application on bistable and open systems. Our study and analysis are completely based on the mixed quantum states quite unlike to the previous investigations based on pure quantum states.
