Microwaves in Quantum Computing

Quantum information processing systems rely on a broad range of microwave technologies and have spurred development of microwave devices and methods in new operating regimes. Here we review the use of microwave signals and systems in quantum computing, with specific reference to three leading quantum computing platforms: trapped atomic ion qubits, spin qubits in semiconductors, and superconducting qubits. We highlight some key results and progress in quantum computing achieved through the use of microwave systems, and discuss how quantum computing applications have pushed the frontiers of microwave technology in some areas. We also describe open microwave engineering challenges for the construction of large-scale, fault-tolerant quantum computers.Comment: Invited review article, to appear in IEEE Journal of Microwaves. 29 pages, 13 figures, $10^{6}$ to $10^{11}$ H

Fourth International Bagpipe Conference

The International Bagpipe Organisation organised the Fourth International Bagpipe Conference to mark International Bagpipe Day 2018 (10 March), a celebration of the world’s diverse bagpipes and bagpiping traditions. Following the success of previous conferences, the upcoming event spread over three days, starting on Friday evening with an opening concert and ending on Sunday afternoon. The conference was held in Palma, Mallorca, where there is a rich and unbroken piping tradition. The conferences are a productive and welcoming platform for all people interested in the study of bagpipes: musicologists, ethnomusicologists, music experts, instrument makers, musicians, composers, dancers and music lovers. This event is an exciting interdisciplinary opportunity to discuss various questions relating to the study of bagpipes both today and historically. All three days are open to the general public and bagpipe enthusiasts are encouraged to attend. As the conference will be held in Catalan speaking territory, papers were welcomed in English, Spanish and Catalan. Simultaneous translation from English to Spanish and Spanish to English was provide

Microbiology and atmospheric processes: an upcoming era of research on bio-meteorology

International audienceFor the past 200 years, the field of aerobiology has explored the abundance, diversity, survival and transport of micro-organisms in the atmosphere. Micro-organisms have been explored as passive and severely stressed riders of atmospheric transport systems. Recently, an interest in the active roles of these micro-organisms has emerged along with proposals that the atmosphere is a global biome for microbial metabolic activity and perhaps even multiplication. As part of a series of papers on the sources, distribution and roles in atmospheric processes of biological particles in the atmosphere, here we describe the pertinence of questions relating to the potential roles that air-borne micro-organisms might play in meteorological phenomena. For the upcoming era of research on the role of air-borne micro-organisms in meteorological phenomena, one important challenge is to go beyond descriptions of abundance of micro-organisms in the atmosphere toward an understanding of their dynamics in terms of both biological and physico-chemical properties and of the relevant transport processes at different scales. Another challenge is to develop this understanding under contexts pertinent to their potential role in processes related to atmospheric chemistry, the formation of clouds, precipitation and radiative forcing. This will require truly interdisciplinary approaches involving collaborators from the biological and physical sciences, from disciplines as disparate as agronomy, microbial genetics and atmosphere physics, for example

Experimental and Computational Study of the Dispersion and Combustion of Wheat Starch and Carbon-Black Particles During the Standard 20L Sphere Test

PresentationThe 20L sphere is one of the standard devices accepted as an international normativity used for dust explosivity characterization. One concern about the effectiveness and reliability of this test is related to the particle size variation due to particles agglomeration and de-agglomeration. These phenomena are determined by the turbulent regime of the dust cloud during the dispersion. This variable must be considered since it determines the uncertainty level of the ignitability and severity parameters of dust combustion. In this context, this study describes the influence of the cloud turbulence on the dust segregation and fragmentation through an experimental and computational study. The behavior of the gas-solid mixture evidenced with the standard rebound nozzle was compared with that observed with six new nozzle geometries. Thereafter, the variations of the Particle Size Distribution (PSD) that occur during the dispersion within the 20L sphere were analyzed for two different powders: carbon-black and micrometric wheat starch. This description is performed with the implementation of two complementary approaches. On the one hand, an experimental approach characterizes the turbulence levels with Particle Image Velocimetry (PIV) tests that are complemented by the description of the PSD variations with granulometric analyses. On the other hand, a computational approach described the dispersion process with CFD-DEM simulations developed in STAR-CCM+ v11.04.010. The simulation results established that the homogeneity assumption is not satisfied with the nozzles compared in this study. Nonetheless, the particles segregation levels can be reduced using nozzles that generate a better dust distribution in the gas-solid injections. Subsequently, an additional first-approach CFD model was established to study the behavior of the combustion step when a starch/air mixture. This model considers the gas- phase reactions of the combustible gases that are produced from the devolatilization of Wheat starch (CO, CH4, C2H4, C2H6, C2H2 and H2) and allowed to establish the approximate fraction of the particle mass that devolatilizes, as well as to confirm that the modelling of the pyrolysis stage is essential for the correct prediction of the maximum rate of pressure rise

WWGENPV 2.0 - A Monte Carlo Event Generator for Four-Fermion Production at e+ e- Colliders

The Monte Carlo program {\tt WWGENPV}, designed for computing distributions and generating events for four-fermion production in $e^+ e^-$ collisions, is described. The new version, 2.0, includes the full set of the electroweak (EW) tree-level matrix elements for double- and single-$W$ production, initial- and final-state photonic radiation including $p_T / p_L$ effects in the Structure Function formalism, all the relevant non-QED corrections (Coulomb correction, naive QCD, leading EW corrections). An hadronisation interface to {\tt JETSET} is also provided. The program can be used in a three-fold way: as a Monte Carlo integrator for weighted events, providing predictions for several observables relevant for $W$ physics; as an adaptive integrator, giving predictions for cross sections, energy and invariant mass losses with high numerical precision; as an event generator for unweighted events, both at partonic and hadronic level. In all the branches, the code can provide accurate and fast results.Comment: LateX file, 23 pages, in press on Computer Physics Communication
