\u201eGoogle Quantum AI\u201c prane\u0161\u0117 pademonstravusi eksperimentin\u012f prover\u017e\u012f, kuris gali suma\u017einti vien\u0105 did\u017eiausi\u0173 kvantini\u0173 kompiuteri\u0173 kli\u016b\u010di\u0173 \u2013 vadinam\u0173j\u0173 magi\u0161k\u0173j\u0173 b\u016bsen\u0173 parengim\u0105.

Magi\u0161kosios b\u016bsenos yra specialios kvantin\u0117s b\u016bsenos, reikalingos universalioms kvantin\u0117ms operacijoms atlikti. Ilg\u0105 laik\u0105 tyr\u0117jai pabr\u0117\u017e\u0117, kad b\u016btent j\u0173 k\u016brimas ir klaid\u0173 taisymas gali \u201esuvalgyti\u201c did\u017ei\u0105j\u0105 dal\u012f kvantinio kompiuterio resurs\u0173, tod\u0117l net ir spar\u010diai tobul\u0117jant aparatin\u0117s \u012frangos kokybei, pa\u017eanga da\u017enai stringa ties \u0161iuo \u017eingsniu.<\/p>\n

Kas yra magi\u0161k\u0173j\u0173 b\u016bsen\u0173 auginimas<\/h2>\n

\u201eGoogle\u201c ai\u0161kina, kad magi\u0161k\u0173j\u0173 b\u016bsen\u0173 auginimas veikia tarsi filtras: \u012f ma\u017e\u0105 lusto srit\u012f \u012fvedama triuk\u0161minga b\u016bsena, o tuomet atliekama koordinuot\u0173 matavim\u0173 seka. Jos tikslas \u2013 aptikti klaidas ir \u201eatmesti\u201c nepavykusius bandymus, paliekant vis \u0161varesn\u0119, ma\u017eiau klaid\u0173 turin\u010di\u0105 b\u016bsen\u0105.<\/p>\n

Pasak bendrov\u0117s, taikant \u0161\u012f metod\u0105 pavyko pasiekti apie 40 kart\u0173 ma\u017eesn\u012f klaid\u0173 lyg\u012f ir T-b\u016bsen\u0173 s\u0105naudas, o loginis tikslumas es\u0105 pasiek\u0117 99,99 proc. Tai reik\u0161minga, nes b\u016btent magi\u0161k\u0173j\u0173 b\u016bsen\u0173 parengimas da\u017enai laikomas brangiausiu \u017eingsniu siekiant klaidoms atsparaus kvantinio skai\u010diavimo.<\/p>\n

K\u0105 tai rei\u0161kia \u201eQ-day\u201c kontekste<\/h2>\n

Diskusijose apie \u201eQ-day\u201c da\u017eniausiai turimas omenyje hipotetinis momentas, kai pakankamai galingas kvantinis kompiuteris gal\u0117t\u0173 prakti\u0161kai \u012fveikti dal\u012f \u0161iandien pla\u010diai naudojam\u0173 vie\u0161ojo rakto kriptografijos schem\u0173. Tokiu atveju rizika paliest\u0173 ne tik kriptovaliut\u0173 operacij\u0173 autorizavim\u0105, bet ir platesn\u0119 interneto bei finans\u0173 infrastrukt\u016br\u0105.<\/p>\n

Vis d\u0117lto pats \u201eGoogle\u201c pristatymas dar nerei\u0161kia, kad toks scenarijus yra \u010dia pat. Bendrov\u0117s tyr\u0117jai pabr\u0117\u017eia, kad reikia didesnio masto demonstracij\u0173, o iki realiai pritaikom\u0173 klaidoms atspari\u0173 kvantini\u0173 sistem\u0173 dar teks spr\u0119sti in\u017einerinius, mastelio ir stabilumo i\u0161\u0161\u016bkius.<\/p>\n

Kod\u0117l ruo\u0161iamasi jau dabar<\/h2>\n

Lygiagre\u010diai technologinei pa\u017eangai vyksta ir per\u0117jimas prie postkvantin\u0117s kriptografijos \u2013 algoritm\u0173, kuriuos b\u016bt\u0173 sunku atakuoti net ir turint didelio masto kvantin\u012f kompiuter\u012f. Organizacijos ir \u012fmon\u0117s vis da\u017eniau vertina, kur j\u0173 sistemose naudojama vie\u0161ojo rakto kriptografija, kiek ilgai turi b\u016bti saugomi duomenys ir kada verta prad\u0117ti migracij\u0105, kad netapt\u0173 aktuali vadinamoji strategija \u201epavogti dabar, i\u0161\u0161ifruoti v\u0117liau\u201c.<\/p>\n
