Ukuphuhliswa kwekhompyutheni ye-quantum enokusombulula iingxaki, ezinokuthi iikhompyutheni ze-classical zizisombulule kuphela ngomzamo omkhulu okanye kungekhona konke-le njongo ngoku ilandelwa yinani elikhulayo lamaqela ophando emhlabeni jikelele. Isizathu: Iziphumo zeQuantum, ezisuka kwihlabathi lezona zinto zincinci kunye nezakhiwo, zivumela usetyenziso olutsha lwetekhnoloji. Okubizwa ngokuba yi-superconductors, evumela ukusetyenzwa kolwazi kunye nemiqondiso ngokwemithetho ye-quantum mechanics, ithathwa njengamacandelo athembisayo okuqonda iikhomputha ze-quantum. Inqaku lokubambelela kwi-superconducting nanostructures, nangona kunjalo, kukuba zisebenza kuphela kumaqondo aphantsi kakhulu kwaye ngoko ke kunzima ukuzisa kwizicelo eziphathekayo. googletag.cmd.push(umsebenzi () {googletag.display('div-gpt-ad-1449240174198-2′);});
Abaphandi kwiYunivesithi yaseMünster kunye neForschungszentrum Jülich ngoku, okokuqala, babonise oko kwaziwa ngokuba yi-quantization yamandla kwi-nanowires eyenziwe ngama-superconductors aphezulu-okuthi i-superconductors, apho iqondo lokushisa liphakanyisiwe ngaphantsi apho i-quantum mechanical effects ilawula. I-superconducting nanowire ke ithatha kuphela amandla akhethiweyo anokuthi asetyenziswe ukubethelela ulwazi. Kwi-superconductors ephezulu yokushisa, abaphandi baye bakwazi ukujonga okokuqala ukuxutywa kwe-photon enye, i-particle yokukhanya ekhonza ukuhambisa ulwazi.
Kwelinye icala, iziphumo zethu zinokufaka isandla ekusetyenzisweni kwetekhnoloji yokupholisa ngokulula kakhulu kwitekhnoloji ye-quantum kwixesha elizayo, kwaye kwelinye icala, zisinika ulwazi olutsha ngokupheleleyo kwiinkqubo ezilawula i-superconducting states kunye ne-dynamics yazo, ekhoyo nangoku. ayiqondwa,” ugxininisa inkokeli yophando uNjingalwazi uCarsten Schuck weZiko leFiziksi kwiYunivesithi yaseMünster. Iziphumo ke ngoko zinokuba zezifanelekileyo kuphuhliso lweentlobo ezintsha zeteknoloji yekhompyutha. Uphononongo lupapashwe kwiphephancwadi loNxibelelwano lweNdalo.
Izazinzulu zasebenzisa ii-superconductors ezenziwe ngezinto ze-yttrium, i-barium, i-copper oxide kunye ne-oxygen, okanye i-YBCO ngokufutshane, apho benza khona iingcingo ezincinci ze-nanometer. Xa ezi zakhiwo ziqhuba amandla ombane akhoyo abizwa ngokuba 'yi-phase slips' iyenzeka. Kwimeko ye-YBCO nanowires, ukuguquguquka koxinzelelo lwe-carrier carrier kubangela ukuhluka kwi-supercurrent. Abaphandi baphanda iinkqubo kwii-nanowires kumaqondo okushisa angaphantsi kwe-20 Kelvin, ehambelana ne-253 degrees Celsius. Ngokudibanisa nezibalo zemodeli, babonise ubuninzi belizwe lamandla kwi-nanowires. Iqondo lobushushu eziye langena ngalo iingcingo kwi-quantum state lafunyanwa kwi-12 ukuya kwi-13 iKelvin—iqondo lobushushu eliphindwe kalikhulu kunobushushu obufunekayo kwizinto eziqhelekileyo ezisetyenziswayo. Oku kwenze ukuba oosonzululwazi bakwazi ukuvelisa iiresonators, oko kukuthi, ii-oscillating systems ezilungelelaniswe neefrikhweri ezithile, ezinobomi obude kunye nokugcina ubume bomatshini bequantum ixesha elide. Oku yimfuneko kuphuhliso lwexesha elide lweekhompyuter ezininzi ezihlala zinkulu.
Amanye amacandelo abalulekileyo kuphuhliso lwetekhnoloji yequantum, kodwa okunokwenzeka kuxilongo lwezonyango, zizichongi ezinokubhalisa neefotoni enye. Iqela lophando likaCarsten Schuck kwiYunivesithi yaseMünster sele lisebenze iminyaka eliqela ekuphuhliseni ezo detectors zinefoto enye esekwe kwiisuperconductors. Yintoni esele isebenza kakuhle kumaqondo okushisa aphantsi, izazinzulu emhlabeni wonke ziye zazama ukufikelela kunye ne-high-temperature superconductors iminyaka engaphezu kweshumi. Kwi-YBCO nanowires esetyenziselwa isifundo, lo mzamo uphumelele ngoku okokuqala. "Izinto esizifumeneyo ezitsha zivula indlela yeenkcazo zethiyori ezingqinisisekayo kunye nophuhliso lwetekhnoloji," utshilo umbhali-mbhali uMartin Wolff ophuma kwiqela lophando laseSchuck.
