[ ngjitur: nj\u00eb kriostat-kompjuter kuantik i “Qendr\u00ebs Kompjuterike Leibniz” (n\u00eb Garching, Bavari, Gjermani), qendra Leibniz e festonte 60-vjetorin e vet n\u00eb v. 2022 – dhe djathtas, Presidenti Joe Biden duke e shikuar nj\u00eb kompjuter kuantik gjat\u00eb vizit\u00ebs s\u00eb objektit t\u00eb IBM n\u00eb Nju Jork, 2022 – IBM pati njoftuar p\u00ebr nj\u00eb investim prej 20 miliard\u00eb $ n\u00eb Informatik\u00ebn Kuantike – fotot via Getty<\/em> ]<\/p>\n

N\u00eb v. 2019 Google pati th\u00ebn\u00eb se m\u00eb n\u00eb fund e kan\u00eb arritur “supremacin\u00eb kuantike” [ pata shkruar p\u00ebr k\u00ebt\u00eb nj\u00eb koment, mund t\u00eb lexohet n\u00eb blog-faqen personale<\/strong><\/a><\/em> ]
\nGoogle qe mburrur duke th\u00ebn\u00eb se, derisa kuantum-kompjuterit t\u00eb tyre i jan\u00eb nevojitur 200 sekonda, p\u00ebr ta kryer operacionin e nj\u00ebjt\u00eb super-kompjuterit t\u00eb IBM do i duheshin rreth 10.000 vjet. At\u00ebbot\u00eb IBM e kishte kompjuterin “klasik” m\u00eb t\u00eb fuqish\u00ebm, quhej “Summit” (tani nuk di kush \u00ebsht\u00eb kampion, mund t’jen\u00eb dhe kinez\u00ebt).<\/p>\n

Lidhur me pohimin e Google ekspert\u00ebve t\u00eb IBM u pati ardhur fort inat. Sakaq qen\u00eb p\u00ebrgjigjur me publikimin e nj\u00eb “letre” shkencore duke th\u00ebn\u00eb se super-kompjuterit t\u00eb tyre n\u00eb fakt do i nevojiteshin vet\u00ebm 2.5 dit\u00eb. IBM pati th\u00ebn\u00eb q\u00eb kuantist\u00ebt e Google flasin me superlativa jorealistik\u00eb, nuk \u00ebsht\u00eb e v\u00ebrtet\u00eb, nuk e kan\u00eb arritur “supremacin\u00eb kuantike”.<\/p>\n

P\u00ebr ta kuptuar (apo dhe moskuptuar) mosmarr\u00ebveshjen e tyre, sikur varet nga vet\u00eb termi “supremaci kuantike” – pata shkruar. \u00c7’do t\u00eb thot\u00eb termi ekzakt\u00ebsisht, kjo po ashtu sikur \u00ebsht\u00eb di\u00e7 “relative” dhe varet kujt i drejtohemi. Termin “supremaci\u2026” apo ep\u00ebrsi kuantike e pati kalitur fizikanti John Preskill n\u00eb v. 2012 (Instituti i Teknologjis\u00eb, Kaliforni). Atij i qe nevojitur p\u00ebr ta p\u00ebrshkruar momentin kur nj\u00eb kuantum-kompjuter m\u00eb n\u00eb fund e tejkalon kompjuterin m\u00eb t\u00eb fuqish\u00ebm klasik.<\/p>\n

N\u00eb Qershor t\u00eb 2023 (pra vitin e kaluar), pati ndodhur i “nj\u00ebjti skenar” i mburravecll\u00ebkut kuantik, k\u00ebsaj radhe nuk qe mburrur Google por ata t\u00eb IBM.<\/p>\n

Ekipi i informatik\u00ebs kuantike pran\u00eb IBM e pati p\u00ebrdorur nj\u00eb prototip t\u00eb kompjuterit kuantik p\u00ebr ta zgjidhur nj\u00eb problem t\u00eb nd\u00ebrlikuar t\u00eb fizik\u00ebs (lidhur me sjelljen e materialeve magnetike). IBM e pati krahasuar eksperimentin kuantik me nj\u00eb simulim klasik (n\u00eb nj\u00eb superkompjuter klasik). K\u00ebtij t\u00eb fundit do t’i nevojitej shum\u00eb m\u00eb shum\u00eb koh\u00eb p\u00ebr ta arritur t\u00eb nj\u00ebjtin rezultat (t\u00eb homologut kuantik), e po ashtu procesi shkonte duke u b\u00ebr\u00eb gjithnj\u00eb e m\u00eb i pasakt\u00eb, pasi ata vazhdonin me rritjen e kompleksitetit t\u00eb problemit. Dhe si\u00e7 pat\u00ebn konkluduar ekipi i IBM, kompjuteri klasik nuk do t’ishte n\u00eb gjendje ta vazhdonte “gar\u00ebn” me kuantikat.<\/p>\n

Mir\u00ebpo pretendimi i IBM nuk do zgjaste shum\u00eb, vet\u00ebm 2 jav\u00eb m\u00eb von\u00eb, nj\u00eb ekip i pavarur e pati demonstruar nj\u00eb simulim klasik, madje n\u00eb nj\u00eb kompjuter portativ (laptop). S\u00ebshpejti do pasonin dhe 6 simulime tjera klasike, duke p\u00ebrdorur teknika t\u00eb ndryshme. Pra as q\u00eb b\u00ebhej fjal\u00eb p\u00ebr “supremaci kuantike”, i bie se IBM mburrej kot. Google qe mburrur n\u00eb v. 2019, ata t\u00eb IBM u pat\u00ebn th\u00ebn\u00eb “s’keni pse ekzagjeroni”. Pak vite m\u00eb von\u00eb, n\u00eb v. 2023 vet\u00eb IBM pandeh arritjen e “supremacis\u00eb kuantike”, por s’u zgjati as 2 jav\u00eb, rishtas doli t’jet\u00eb e pav\u00ebrtet\u00eb : )<\/p>\n

E \u00e7uditshme, se p\u00ebrse ndodh\u00eb kjo gar\u00eb e mburravecll\u00ebkut mes tekno-gjigant\u00ebve mund vet\u00ebm t\u00eb hamend\u00ebsojm\u00eb. Sot, 5 Shkurt 2024, eksperti i stafit t\u00eb shkencave kompjuterike pran\u00eb revist\u00ebs “Quanta M”, Ben Brubaker, e paska publikuar nj\u00eb artikull rreth tem\u00ebs pse kompjuter\u00ebt kuantik\u00eb ende nuk i kan\u00eb tejkaluar bindsh\u00ebm “homolog\u00ebt” e tyre klasik\u00eb. Sapo e lexova shkrimin e tij, n\u00eb rregull autori Brubaker ia mbante pak\u00ebz m\u00eb rrotull, por dhe ai sikur buz\u00ebqeshte me mburravecll\u00ebkun rreth kuantikave.
