actualment s\u2019est\u00e0 instal\u00b7lant la primera unitat de processament qu\u00e0ntic: QPU (Quantum Processing Unit).<\/p>\n<p style=\"text-align: justify;\">Durant la visita s\u2019ha explicat\u00a0que la QPU es troba encara en una fase experimental, lluny d\u2019un \u00fas en producci\u00f3, per\u00f2 que el desenvolupament d\u2019algorismes de correcci\u00f3 d\u2019errors qu\u00e0ntics permetr\u00e0 millorar la fiabilitat del processament qu\u00e0ntic en un futur pr\u00f2xim.<\/p>\n<p style=\"text-align: justify;\">Format per qubits superconductors, extremadament sensibles a la temperatura i a les interfer\u00e8ncies, el sistema requerir\u00e0 un cri\u00f2stat de diluci\u00f3 (estructura recoberta d&#8217;or), que permet una refrigeraci\u00f3 per capes fins a temperatures molt a prop del zero absolut.<\/p>\n<p style=\"text-align: justify;\">Una visita molt enriquidora que ha apropat l\u2019alumnat a la supercomputaci\u00f3 i a la tecnologia qu\u00e0ntica del futur.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-large wp-image-18966 aligncenter\"
