Africa-Press – Senegal. <\/strong><\/span>Dans une avance\u0301e majeure, une e\u0301quipe de l’Universite\u0301 des sciences et technologies de Chine a de\u0301voile\u0301 le processeur quantique \u00ab\u00a0Zuchongzhi-3\u00a0\u00bb, une perce\u0301e dans la supre\u0301matie quantique.<\/p>\n

Compose\u0301 de 105 qubits, \u00ab\u00a0Zuchongzhi-3\u00a0\u00bb est l\u2019un des processeurs quantiques les plus avance\u0301s, capable d\u2019effectuer des calculs un million de fois plus rapides que les re\u0301sultats re\u0301cents de Google, et un quadrillion de fois plus rapide que les superordinateurs classiques.<\/p>\n

Ce de\u0301veloppement s\u2019inscrit dans la continuite\u0301 des succe\u0300s pre\u0301ce\u0301dents de l’e\u0301quipe avec \u00ab\u00a0Zuchongzhi-1\u00a0\u00bb et \u00ab\u00a0Zuchongzhi-2\u00a0\u00bb.<\/p>\n

Asmaa Ali, chercheuse en physique the\u0301orique a\u0300 l\u2019Universite\u0301 de Mansoura en E\u0301gypte, a de\u0301clare\u0301 que cette avance\u0301e repre\u0301sente un tournant dans la compre\u0301hension des capacite\u0301s naturelles au service de l’intelligence artificielle, de la technologie et de la civilisation humaine.<\/p>\n

Ordinateur tre\u0300s spe\u0301cial<\/b><\/p>\n

Contrairement aux ordinateurs classiques utilisant des bits (0 ou 1), l’ordinateur quantique utilise des qubits pouvant e\u0302tre 0 et 1 simultane\u0301ment, re\u0301alisant ainsi un grand nombre d’ope\u0301rations en paralle\u0300le.<\/p>\n

Asmaa Ali explique que le chevauchement quantique permet aux qubits de repre\u0301senter plusieurs e\u0301tats a\u0300 la fois, tandis que l’intrication quantique relie les qubits, leur permettant de re\u0301agir instantane\u0301ment l’un a\u0300 l’autre me\u0302me a\u0300 distance.<\/p>\n

Gra\u0302ce e\u0301galement aux interfe\u0301rences quantiques, les algorithmes peuvent renforcer les bons re\u0301sultats et annuler les erreurs, ce qui est impossible pour les ordinateurs classiques.<\/p>\n

Guerre froide quantique<\/b><\/p>\n

En 2019, Google a revendique\u0301 la supre\u0301matie quantique avec \u00ab\u00a0Sycamore\u00a0\u00bb (53 qubits), capable d\u2019effectuer en 200 secondes un calcul ne\u0301cessitant 10 000 ans pour un superordinateur classique.<\/p>\n

Cependant, l’e\u0301quipe chinoise a de\u0301fie\u0301 Google avec \u00ab\u00a0Zuchongzhi-3\u00a0\u00bb, surpassant ses meilleurs processeurs.<\/p>\n

Asmaa Ali souligne que la supre\u0301matie quantique permet de re\u0301soudre en quelques secondes des proble\u0300mes ne\u0301cessitant des milliards d’anne\u0301es pour les superordinateurs classiques.<\/p>\n

Ge\u0301nie de Zuchongzhi-3<\/b><\/p>\n

Asmaa Ali explique que le plus grand de\u0301fi est de mai\u0302triser le bruit qui pourrait faire s’effondrer l’e\u0301tat quantique. Le \u00ab\u00a0Zuchongzhi-3\u00a0\u00bb utilise des mate\u0301riaux spe\u0301ciaux et une architecture avance\u0301e pour minimiser les interfe\u0301rences et ame\u0301liorer la fiabilite\u0301.<\/p>\n

Le processeur atteint une dure\u0301e de cohe\u0301rence de 72 microsecondes et un taux de pre\u0301cision de 99,9 %, re\u0301duisant le besoin de corrections d\u2019erreurs et ame\u0301liorant la stabilite\u0301.<\/p>\n

Cela permet des simulations physiques avance\u0301es, la re\u0301solution de proble\u0300mes complexes et des applications en intelligence artificielle et cryptographie.<\/p>\n

Entre passe\u0301 et pre\u0301sent<\/b><\/p>\n

Le de\u0301veloppement de la technologie quantique vise a\u0300 maintenir les e\u0301tats quantiques tout en minimisant les perturbations.<\/p>\n

Le superordinateur est nomme\u0301 d’apre\u0300s Zuchongzhi, ce\u0301le\u0300bre mathe\u0301maticien chinois ayant contribue\u0301 a\u0300 des calculs astronomiques comme l\u2019approximation de \u03c0.<\/p>\n

Asmaa Ali note que la capacite\u0301 de l\u2019ordinateur quantique a\u0300 traiter des calculs complexes en exploitant la superposition et l\u2019intrication aurait stupe\u0301fie\u0301 Zuchongzhi, transformant notre compre\u0301hension classique des mathe\u0301matiques en un domaine probabiliste.<\/p>\n

Apre\u0300s cette perce\u0301e, l’e\u0301quipe chinoise travaille a\u0300 l’ame\u0301lioration de la correction d\u2019erreurs quantiques et du niveau d\u2019intrication, ouvrant la voie a\u0300 des applications re\u0301volutionnaires dans le monde entier.<\/p>\n
