Abstract
(EN)
According to some aspects, a circuit is provided comprising a plurality of Josephson junctions arranged in series in a loop, at least one magnetic element producing magnetic flux through the loop, a plurality of superconducting resonators, each resonator coupled to the loop between a different neighboring pair of Josephson junctions of the plurality of Josephson junctions, a plurality of ports, each port coupled to at least one of the plurality of resonators at ends of the resonators opposite to ends at which the resonators are coupled to the loop, and at least one controller configured to provide input energy to each of the plurality of ports that causes the circuit to function as a circulator between the plurality of ports.
(FR)
Selon certains aspects, l'invention concerne un circuit comprenant une pluralité de jonctions Josephson disposées en série dans une boucle, au moins un élément magnétique produisant un flux magnétique à travers la boucle, une pluralité de résonateurs supraconducteurs, chaque résonateur étant couplé à la boucle entre une paire de jonctions Josephson voisines différentes de la pluralité de jonctions de Josephson, une pluralité de ports, chaque port étant couplé à au moins l'un des résonateurs de la pluralité de résonateurs sur des extrémités des résonateurs opposées aux extrémités sur lesquelles les résonateurs sont couplés à la boucle, et au moins un contrôleur conçu pour fournir une énergie d'entrée à chacun des ports de la pluralité de ports, ce qui amène le circuit à fonctionner comme un circulateur entre la pluralité de ports.
