Kuvandudzwa kwekombuta yehuwandu inogona kugadzirisa matambudziko, ayo ekare makomputa anogona chete kugadzirisa nekuedza kukuru kana kusatombodaro-ichi ndicho chinangwa chiri kuteverwa nenhamba inoramba ichikura yezvikwata zvekutsvagisa pasi rese. Chikonzero: Quantum mhedzisiro, iyo inotangira kubva pasirese diki zvidimbu uye zvimiro, inogonesa akawanda matsva tekinoroji application. Vanodaidzwa kuti superconductors, iyo inobvumira kugadzirisa ruzivo uye zviratidzo maererano nemitemo ye quantum mechanics, inoonekwa sezvikamu zvinovimbisa zvekuziva quantum makomputa. Chinhu chinonamira che superconducting nanostructures, zvisinei, ndechekuti inongoshanda patembiricha yakadzika kwazvo uye saka yakaoma kuunza mune inoshanda maapplication. googletag.cmd.push(basa() {googletag.display('div-gpt-ad-1449240174198-2′);});
Vatsvakurudzi vepaYunivhesiti yeMünster uye Forschungszentrum Jülich ikozvino, kekutanga, vakaratidza izvo zvinozivikanwa sesimba quantization mu nanowires yakagadzirwa nepamusoro-tembiricha superconductors-kureva superconductors, umo tembiricha inokwidziridzwa pazasi iyo quantum mechanical madhara inotungamira. Iyo superconducting nanowire inobva yatora chete yakasarudzwa simba nyika inogona kushandiswa encode ruzivo. Mu-high-temperature superconductors, vatsvakurudzi vakakwanisawo kutarisa kwekutanga kutorwa kwephoton imwe chete, chiedza chechiedza chinoshumira kutumira ruzivo.
"Kune rimwe divi, mhedzisiro yedu inogona kubatsira mukushandiswa kwakareruka kutonhora tekinoroji mune quantum tekinoroji mune ramangwana, uye kune rimwe divi, vanotipa ruzivo rutsva mumaitiro anotonga superconducting nyika nemasimba adzo, ayo achiri. zvisinganzwisisike,” anosimbisa mutungamiriri wezvidzidzo Jun Prof. Carsten Schuck kubva kuInstitute of Physics paMünster University. Naizvozvo mhedzisiro yacho inogona kuve yakakosha pakuvandudzwa kwemhando itsva dzetekinoroji yekombuta. Chidzidzo ichi chakaburitswa mujenari Nature Communications.
Masayendisiti akashandisa superconductors akagadzirwa nezvinhu yttrium, barium, copper oxide uye oxygen, kana YBCO kwenguva pfupi, kubva kwavakagadzira mashoma nanometer waya dzakatetepa. Kana zviumbwa izvi zvinoitisa magetsi emazuva ano masimba anonzi 'phase slips' anoitika. Panyaya yeYBCO nanowires, kuchinjika kwechaji carrier density kunokonzera mutsauko mune supercurrent. Vatsvakurudzi vakaongorora maitiro mu nanowires patembiricha iri pasi pe20 Kelvin, iyo inoenderana ne253 degrees Celsius. Mukubatana nemuenzaniso kuverenga, vakaratidza quantization yesimba renyika mune nanowires. Tembiricha apo waya dzakapinda muquantum state yakawanikwa pa12 kusvika ku13 Kelvin—tembiricha yakapetwa nemazana akati wandei pane tembiricha inodiwa pazvinhu zvinowanzoshandiswa. Izvi zvakagonesa masayendisiti kuburitsa resonators, kureva masisitimu anotenderedza akaiswa kune chaiwo ma frequency, ane hupenyu hwakareba uye kuchengetedza quantum mechanicha nyika kwenguva refu. Ichi chinhu chinodiwa pakuvandudzwa kwenguva refu kwemakomputa akakura equantum.
Zvimwe zvakakosha zvekuvandudza tekinoroji yequantum, asi zvingangoita zvekuongorora zvekurapa, madetector anogona kunyoresa kunyange mafotoni mamwechete. Boka rekutsvagisa raCarsten Schuck paMünster University rave richishanda kwemakore akati wandei mukugadzira maonesheni e-single-photon anoenderana nemasuperconductors. Izvo zvinotoshanda zvakanaka pakudziya kwakadzika, masayendisiti pasi rese anga achiedza kuita nepamusoro-tembiricha superconductors kweanopfuura makore gumi. MuYBCO nanowires inoshandiswa pakudzidza, kuedza uku kwabudirira kekutanga. "Zvatinowana zvitsva zvinovhura nzira yetsananguro itsva dzinogoneka dzedzidziso uye budiriro yetekinoroji," anodaro munyori pamwe naye Martin Wolff weboka rekutsvaga reSchuck.
