چکیده

It is a popular idea that a multi-partite quantum system represented by a density matrix having no product eigenbasis possesses non-classical correlation. Supporting this idea, we define an entropic measure of non-classical correlation on the basis of the minimum uncertainty about a joint-system after we collect reports of particular local measurements. Numerical computation of this measure for several examples is performed. PACS numbers: 03.65.Ud, 05.30.Ch, 02.60.-x Non-classical correlation in a multi-partite quantum system reconsidered 2

Characterizing the combinatorics of distributed EPR pairs for multi-partite entanglement

We develop protocols for preparing a GHZ state and, in general, a pure multi-partite maximally entangled state in a distributed network with apriori quantum entanglement between agents using classical communication and local operations. We investigate and characterize the minimal combinatorics of the sharing of EPR pairs required amongst agents in a network for the creation of multi-partite ent...

Calculation of Kolmogorov Entropy in Cavity Quantum Electrodynamics

In this paper Kolomogorov entropy of a simulated cavity quantum electrodynamics in a multi-partite system consisting of eight quantum dots in interaction with one cavity mode has been estimated. It has been shown that the Kolmogorov Entropy monotonically increases with the increasing coupling strength, which is a sufficient condition for chaotic behavior under ultrastrong coupling regime. The a...

Multi-partite entanglement, communication complexity and quantum Helly-type theorems

We develop protocols for preparing the GHZ state (a pure tri-partite maximally entangled state) and, in general, a pure n-partite maximally entangled state using EPR pairs shared amongst n agents and classical communication between the agents. We observe that the combinatorial arrangement of EPR pairs required for this purpose is like that in Helly-type theorems in geometry. PACS numbers: 03.65...

Implication of Quantum Effects on Non-Linear Propagation of Electron Plasma Solitons

We have studied the electron exchange-correlation effect on thecharacteristics of the two-component unmagnetized dense quantum plasma withstreaming motion. For this purpose, we have used the quantum hydrodynamic model(including the effects of a quantum statistical Fermi electron temperature) for studyingthe propagation of an electrostatic electron plasma waves in such th...

Limitations on testing quantum theory

How much of quantum theory can be experimentally tested? We investigate this question in an extreme scenario, where the experimenter cannot make any assumptions on the quantum description of a device or state. Instead, she can only directly manipulate and interpret classical information. We prove that in this scenario, there is almost nothing that she can ascertain about the internal state of a...
