Patent number: 11302856Abstract: The present invention relates to an inductive dipole element for a superconducting microwave quantum circuit. The dipole element comprises a DC-SQUID formed by a pair of Josephson junctions shunted by an inductance, wherein the Josephson junctions have equal energy, and the Josephson junctions and the inductance are arranged such that each of the junctions forms a loop with the inductance. The two loops are asymmetrically threaded with external magnetic DC fluxes ?ext1 and ?ext2, respectively, such that ?ext1=? and ?ext2=0, wherein parametric pumping is enabled by modulating the total flux ??=?ext,1+?ext,2 threading the dipole element, thereby allowing even-wave mixing between modes that participate in the dipole element with no Kerr-like interactions.Type: GrantFiled: January 24, 2020Date of Patent: April 12, 2022Assignees: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, ECOLE NATIONALE SUPERIEURE DES MINES DE PARIS, ASSOCIATION POUR LA RECHERCHE ET LE DEVELOPPEMENT DES METHODES ET PROCESSUS INDUSTRIELS-ARMINES, ECOLE NORMALE SUPERIEURE, SORBONNE UNIVERSITE, UNIVERSITE DE PARISInventors: Raphaël Lescanne, Zaki Leghtas

Patent number: 10301602Abstract: Production of virus occlusion bodies that occlude virions comprising genomes of different species of baculoviruses that can be used to combat insect pests. A method is presented for the production of occlusion derived virions (ODVs) that simultaneously comprise genomes of different baculovirus species, occluded in a viral occlusion body (OB) with the structural and morphological features characteristic of baculoviruses. Mixed genome ODVs and OBs can be produced by co-infecting insect cells or insect hosts using two or more different baculoviruses species. Co-infection may be achieved by simultaneous inoculation of the different baculoviruses or with a time interval between inoculations, which results in different proportions of each species' genomes in the ODVs and OBs that are produced. The produced OBs can be used either directly for preparing an insecticide, or to infect susceptible insects to produce larger quantities of mixed genome ODVs and OBs, also useful for combating pest insects.Type: GrantFiled: September 23, 2013Date of Patent: May 28, 2019Assignees: UNIVERSIDAD PÚBLICA DE NAVARRA, CONSEJO SUPERIOR DE INVESTIGACIONES CIENTÍFICAS, INSTITUTO DE ECOLOGÍA, A.C., ASSOCIATION POUR LA RECHERCHE ET LE DEVELOPPEMENT DES METHODES ET PROCESSUS INDUSTRIELS (ARMINES)Inventors: Primitivo Caballero Murillo, Inés Beperet Arive, Oihane Simón De Goñi, Trevor Williams, Miguel Lopez-Ferber
