Multimode entanglement in reconfigurable graph states using optical frequency combs
Nature Communications, 2017Co-Authors: Y Cai, F. Arzani, Jonathan Roslund, X. Xu, Gabriele Ferrini, Claude Fabre, Nicolas TrepsAbstract:Multimode entanglement is an essential resource for quantum information processing and quantum metrology. However, multimode entangled states are generally constructed by targeting a specific graph configuration. This yields to a fixed Experimental setup that therefore exhibits reduced versatility and scalability. Here we demonstrate an optical on-demand, reconfigurable multimode entangled state, using an intrinsically multimode quantum resource and a homodyne detection apparatus. Without altering either the initial squeezing source or Experimental architecture, we realize the construction of thirteen cluster states of various sizes and connectivities as well as the implementation of a secret sharing protocol. In particular, this system enables the interrogation of quantum correlations and fluctuations for any multimode Gaussian state. This initiates an avenue for implementing on-demand quantum information processing by only adapting the measurement process and not the Experimental Layout.

A new Experimental Layout for non-aqueous enzymatic syntheses
Journal of Molecular Catalysis B-enzymatic, 2001Co-Authors: Domenico Pirozzi, Guido GrecoAbstract:Abstract The lipase-catalysed synthesis of geranyl caproate has been carried out in a stirred batch reactor. A continuous flow of nitrogen is provided. The gas is pre-equilibrated by bubbling within different vessels upstream from the reactor, in order to insure controlled conditions in terms of water thermodynamic activity. In order to avoid a continuous stripping of the solvent, nitrogen is pre-saturated with the latter as well. Furthermore, nitrogen flow strips out the volatile reaction products, thus beneficially affecting reaction thermodynamics. In order to further exploit the advantages of gas injection, a three-phase fluidised reactor configuration has been tested, where the gas-induced turbulence avoids mechanical stirring.

Optimisation of the weld bead geometry in gas tungsten arc welding by the Taguchi method
The International Journal of Advanced Manufacturing Technology, 1998Co-Authors: Y. S. Tarng, W H YangAbstract:In this paper, determination of the welding process parameters for obtaining an optimal weld bead geometry in gas tungsten arc welding is presented. The Taguchi method is used to formulate the Experimental Layout, to analyse the effect of each welding process parameter on the weld bead geometry, and to predict the optimal setting for each welding process parameter. Experimental results are presented to explain the proposed approach.

application of the taguchi method to the optimization of the submerged arc welding process
Materials and Manufacturing Processes, 1998Co-Authors: Y. S. Tarng, W H YangAbstract:Abstract Application of the Taguchi method to the optimization of the submerged arc welding process is reported. The Taguchi method is used to formulate the Experimental Layout, to analyze the effect of each welding parameter on welding performance, and to predict the optimal setting for each welding parameter. Experimental results are provided to confirm the effectiveness of this approach.
