In this paper, we develop, a quantum key distribution protocol based on the Greenberger-Horne-Zeilinger states (GHZs). The
particles are exchanged among the users in blocks through two steps. In this protocol, for three-particle GHZs three keys
can be simultaneously generated. The advantage of this is that the users can select the most suitable key for communication.
The protocol can be generalized to N users to provide N keys. The protocol has two levels for checking the eavesdroppers. Moreover, we discuss the security of the protocol against
different attacks. 相似文献

Holographic dark energy (HDE), presents a dynamical view of dark energy which is consistent with the observational data and
has a solid theoretical background. Its definition follows from the entropy-area relation S(A), where S and A are entropy and area respectively. In the framework of loop quantum gravity, a modified definition of HDE called “entropy-corrected
holographic dark energy” (ECHDE) has been proposed recently to explain dark energy with the help of quantum corrections to
the entropy-area relation. Using this new definition, we establish a correspondence between modified variable Chaplygin gas,
new modified Chaplygin gas and the viscous generalized Chaplygin gas with the entropy corrected holographic dark energy and
reconstruct the corresponding scalar potentials which describe the dynamics of the scalar field. 相似文献

Motivated by several observational and theoretical developments concerning the variability of Newton’s gravitational constant
with time G(t), we calculate the varying G correction to the statefinder parameters for four models of dark energy namely interacting dark energy holographic dark energy,
new-agegraphic dark energy and generalized Chaplygin gas. 相似文献

We consider the λ model, a generalization of the Potts model, with spin values {1, 2, 3} on the order-two Cayley tree. We describe the model ground states and prove that translation-invariant Gibb measures exist, which means that a phase transition exists. We establish that two-periodic Gibbs measures exist. 相似文献

In this paper, we have calculated the statefinder parameters for the Friedmann-Robertson-Walker (FRW) Universe in the gravitational framework of loop quantum cosmology (LQC). As examples, we study two types of dark energy models namely Holographic dark energy and New-Agegraphic dark energy. 相似文献

In this paper, the metric approach of f(R) theory of gravity is used to investigate the exact vacuum solutions of spatially homogeneous rotating spacetimes. For this purpose, R is replaced by f(R) in the standard Einstein-Hilbert action and the set of modified Einstein field equations reduce to a single equation. We adopt the assumption of constant Ricci scalar which maybe zero or non-zero. Moreover, the energy density of the non-trivial solution has been evaluated by using the generalized Landau-Lifshitz energy-momentum complex in the perspective of f(R) gravity for some appropriate f(R) model, which turns out to be a constant quantity. 相似文献
