    Relations between entanglement, Bell-inequality violation and teleportation fidelity for the two-qubit X states

    Full text link
    Based on the assumption that the receiver Bob can apply any unitary transformation, Horodecki {\it et al.} [Phys. Lett. A {\bf 222}, 21 (1996)] proved that any mixed two spin-1/2 state which violates the Bell-CHSH inequality is useful for teleportation. Here, we further show that any X state which violates the Bell-CHSH inequality can also be used for nonclassical teleportation even if Bob can only perform the identity or the Pauli rotation operations. Moreover, we showed that the maximal difference between the two average fidelities achievable via Bob's arbitrary transformations and via the sole identity or the Pauli rotation is 1/9.Comment: 5 pages, to be published in "Quantum Information Processing

    Teleportation of the one-qubit state with environment-disturbed recovery operations

    We study standard protocol P0\mathcal{P}_0 for teleporting the one-qubit state with both the transmission process of the two qubits constitute the quantum channel and the recovery operations performed by Bob disturbed by the decohering environment. The results revealed that Bob's imperfect operations do not eliminate the possibility of nonclassical teleportation fidelity provided he shares an ideal channel state with Alice, while the transmission process is constrained by a critical time t0,ct_{0,c} longer than which will result in failure of P0\mathcal{P}_0 if the two qubits are corrupted by the decohering environment. Moreover, we found that under the condition of the same decoherence rate γ\gamma, the teleportation protocol is significantly more fragile when it is executed under the influence of the noisy environment than those under the influence of the dissipative and dephasing environments.Comment: 8 pages, 4 figure

    Various correlations in a Heisenberg XXZ spin chain both in thermal equilibrium and under the intrinsic decoherence

    Full text link
    In this paper we discuss various correlations measured by the concurrence (C), classical correlation (CC), quantum discord (QD), and geometric measure of discord (GMD) in a two-qubit Heisenberg XXZ spin chain in the presence of external magnetic field and Dzyaloshinskii-Moriya (DM) anisotropic antisymmetric interaction. Based on the analytically derived expressions for the correlations for the cases of thermal equilibrium and the inclusion of intrinsic decoherence, we discuss and compare the effects of various system parameters on the correlations in different cases. The results show that the anisotropy Jz is considerably crucial for the correlations in thermal equilibrium at zero temperature limit but ineffective under the consideration of the intrinsic decoherence, and these quantities decrease as temperature T rises on the whole. Besides, J turned out to be constructive, but B be detrimental in the manipulation and control of various quantities both in thermal equilibrium and under the intrinsic decoherence which can be avoided by tuning other system parameters, while D is constructive in thermal equilibrium, but destructive in the case of intrinsic decoherence in general. In addition, for the initial state Ψ1(0)>=12(01>+10>)|\Psi_1(0) > = \frac{1}{\sqrt{2}} (|01 > + |10 >), all the correlations except the CC, exhibit a damping oscillation to a stable value larger than zero following the time, while for the initial state Ψ2(0)>=12(00>+11>)|\Psi_2(0) > = \frac{1}{\sqrt{2}} (|00 > + |11 >), all the correlations monotonously decrease, but CC still remains maximum. Moreover, there is not a definite ordering of these quantities in thermal equilibrium, whereas there is a descending order of the CC, C, GMD and QD under the intrinsic decoherence with a nonnull B when the initial state is Ψ2(0)>|\Psi_2(0) >.Comment: 8 pages, 7 figure

    Search for sterile neutrino oscillation using RENO and NEOS data

    Full text link
    We present a reactor model independent search for sterile neutrino oscillation using 2\,509\,days of RENO near detector data and 180 days of NEOS data. The reactor related systematic uncertainties are significantly suppressed as both detectors are located at the same reactor complex of Hanbit Nuclear Power Plant. The search is performed by electron antineutrino\,(νe\overline{\nu}_e) disappearance between six reactors and two detectors with baselines of 294\,m\,(RENO) and 24\,m\,(NEOS). A spectral comparison of the NEOS prompt-energy spectrum with a no-oscillation prediction from the RENO measurement can explore reactor νe\overline{\nu}_e oscillations to sterile neutrino. Based on the comparison, we obtain a 95\% C.L. excluded region of 0.1<Δm412<70.1<|\Delta m_{41}^2|<7\,eV2^2. We also obtain a 68\% C.L. allowed region with the best fit of Δm412=2.41±0.03|\Delta m_{41}^2|=2.41\,\pm\,0.03\,\,eV2^2 and sin22θ14\sin^2 2\theta_{14}=0.08±\,\pm\,0.03 with a p-value of 8.2\%. Comparisons of obtained reactor antineutrino spectra at reactor sources are made among RENO, NEOS, and Daya Bay to find a possible spectral variation.Comment: 6 pages, 5 figures: This manuscript has been significantly revised by the joint reanalysis by RENO and NEOS Collaborations. (In the previous edition, the RENO collaboration used publicly available NEOS data to evaluate the expected neutrino spectrum at NEOS.

    Managing the Future of de Bijenkorf: Towards the Real Estate Management Strategy of a Dutch Upscale Department Store Chain

    No full text
    This master’s thesis is the advisory Real Estate Management Report for the future development strategy of the Dutch upscale department store, de Bijenkorf. Upscale department stores build its characteristic by having invited selected brands, and have specific target group who have higher purchasing power than average, and now de Bijenkorf is the only upscale department store brand in the Netherlands. To take care of its target customers, it has prepared for the commensurate assortment of brands with various departments for the customers’ tastes. As we realize that the department store itself has an image of an old fashioned retail format comparing to other newly developed retail formats, it may look decreasing retail business in these days. However, it still shows that the big retailer in the city center needs to be prepared more properly by predicting the future demands of the cities not only for their business profitability but also for the city’s image or branding. They need to keep this business and prepare more properly for the future. This report is not about how department stores can dominate the future retail market, but about how department stores sophisticatedly can keep and sustain their business more effectively into the retail market of the city. This is all about how to prepare the future of the department stores more strategically by providing research, business strategy, scenario planning and recommendation about efficient future transition of Dutch upscale department store chains, de Bijenkorf.Real Estate Management / Leisure & Retail LaboratoryReal Estate & HousingArchitectur
