There is provided a quantum computing circuit comprising first and second superconductive magnetic flux quantum bit elements (101, 102) and a coupling superconductive magnetic flux quantum bit element (103). The first and second superconductive magnetic flux quantum bit elements form superconductive loops including a plurality of Josephson junctions, are biased at a half-quantum magnetic flux, and have mutually different characteristic frequencies. The coupling superconductive magnetic flux quantum bit element performs variable control between the elements (101, 102) in a parametric way by applying a microwave magnetic field pulse equal tothe frequency difference between the elements (101, 102).
La présente invention concerne un circuit de calcul quantique comportant des premier et second éléments de bits quantiques de flux magnétique supraconducteur (101, 102) et un élément de bit quantique de flux magnétique de couplage (103). Les premier et second éléments de bits quantiques de flux magnétique supraconducteur forment des boucles supraconductrices comprenant une pluralité de jonctions de Josephson, sont polarisés à un flux magnétique semi-quantique, et ont des fréquences caractéristiques différentes. L'élément de bit quantique de flux magnétique de couplage effectue une commande variable entre les éléments (101, 102) de manière paramétrique par l'application d'une impulsion de champ magnétique hyperfréquence égale à la différence de fréquence entre les éléments (101, 102).
