Controlled Teleportation of Two-Partic le Entanglement via a Cluster State

In order to teleport an unknown two-particle entangled state via a cluster state,a controlled teleportation scheme is proposed.It is shown that an unknown two-particle entangled state can be successfully transmitted from the sender Alice to the receiver Bob with the help of the supervisor Charlie via the only one four-particle cluster state.The receiver can reconstruct the teleported state according to the measurement results of the sender and supervisor.Quantum Controlled-NOT (CNOT) gate and POVM are used,which have been accomplished in a quantum experiment,so it is believed that this scheme will be realized by experiment.By analysis,the success probability of the proposed scheme reaches 1.0.

A New Optimal Control System Design for Chemical Processes

Based on frequency response and convex optimization,a novel optimal control system was developed for chemical processes.The feedforward control is designed to improve the tracking performance of closed loop chemical systems.The parametric model is not required because the system directly utilizes the frequency response of the loop transfer function,which can be measured accurately.In particular,the extremal values of magnitude and phase can be solved according to constrained quadratic programming optimizer and convex optimization.Simulation examples show the effectiveness of the method.The design method is simple and easily adopted in chemical industry.

Solvothermal Preparation of Mn_3O_4 Nanoparticles and Effect of Temperature on Particle Size

Hausmannite Mn3O4 nanoparticles were successfully prepared via a facile one-step solvothermal route with Mn（CH3COO）2·4H2O as manganese source in the mixed solvent of acetone and water.Powder X-ray diffraction（XRD）,Fourier transform infrared（FTIR） spectrometry and transmission electron microscopy（TEM） were used to characterize Mn3O4 nanoparticles.It was found that the particle size could be tailored by varying the synthesis temperature.On the whole,the particle size becomes larger with the rising of solvothermal reaction temperature.But there is no linear relation between them.According to the different temperatures（60―140 °C）,the average particle size is from about 9 nm to 15 nm.Magnetic properties of Mn3O4 samples prepared at 60,100 and 140 °C were studied via a superconducting quantum interference device（SQUID）,respectively.

White organic light-emitting diodes based on emission from DPVBi-doped 4,48-bis (2,28-diphenylvinyl)-1,18-biphenyl

White organic light-emitting diodes were fabricated by using 4,48-bis （2,28-diphenylvinyl）-1,18-biphenyl （DPVBi） as a dopant with a structure of ITO/4,4′-bis[N-（1-naphthyl-1-）-N-phenyl-amino]-biphenyl （NPB,50 nm）/NPB:DPVBi （molecular weight ratio 10∶1,30 nm）/tris-（8-hydroxyquinoline）aluminum（Alq3,20 nm）/LiF（1 nm）/Al.A broad emissive band with four major peaks of 438,464,496 and 520 nm was obtained by electroluminescence spectra,of which 438 nm-,464 nm-and 520 nm-peak come from emission of NPB,DPVBi and Alq3,respectively,and 496 nm-one resulted from the emissive superposition of three materials above.The emission from DPVBi was attributed to the charge trapping from NPB.The emission region was transferred partly from Alq3 to DPVBi-doped NPB by introducing the dopant DPVBi,which leads to emission of DPVBi and an enhanced emission from NPB.The maximum luminance and current efficiency were 4721 cd/m2 at 22 V and 0.80 cd/A at 5V,respectively.
