Ubuchwepheshe be-Quantum: Ukuqonda okusha ngezinqubo ze-superconducting

Ukuthuthukiswa kwekhompuyutha ye-quantum ekwazi ukuxazulula izinkinga, amakhompiyutha we-classical akwazi ukuzixazulula kuphela ngomzamo omkhulu noma cha nhlobo-lena inhloso okwamanje elandelwa inani elikhulayo lamaqembu ocwaningo emhlabeni wonke. Isizathu: Imiphumela ye-Quantum, eqhamuka emhlabeni wezinhlayiya nezakhiwo ezincane kakhulu, inika amandla izinhlelo eziningi zobuchwepheshe ezintsha. Okubizwa ngokuthi ama-superconductors, avumela ukucutshungulwa kolwazi kanye namasignali ngokuvumelana nemithetho ye-quantum mechanics, kubhekwa njengezingxenye ezithembisayo zokuqaphela amakhompyutha we-quantum. Iphuzu elinamathelayo lama-superconducting nanostructures, nokho, ukuthi asebenza kuphela emazingeni okushisa aphansi kakhulu ngakho-ke kunzima ukuwenza ekusebenzeni okungokoqobo. googletag.cmd.push(umsebenzi() {googletag.display('div-gpt-ad-1449240174198-2′); });

Abacwaningi baseNyuvesi yaseMünster kanye neForschungszentrum Jülich manje, ngokokuqala ngqa, babonise lokho okwaziwa ngokuthi amandla quantization kuma-nanowires enziwe ngama-superconductors asezingeni eliphezulu—okungukuthi ama-superconductors, lapho izinga lokushisa likhuphuka ngezansi lapho imiphumela yemishini ye-quantum ibusa kakhulu. I-superconducting nanowire bese ithatha izifunda zamandla ezikhethiwe kuphela ezingasetshenziswa ukufaka ikhodi yolwazi. Ku-high-temperature superconductors, abacwaningi bakwazi nokubona okokuqala ukumuncwa kwe-photon eyodwa, inhlayiya yokukhanya ekhonza ukudlulisa ulwazi.

“Ngakolunye uhlangothi, imiphumela yethu ingaba nomthelela ekusetshenzisweni kobuchwepheshe bokupholisa obenziwe lula kakhulu kubuchwepheshe be-quantum esikhathini esizayo, futhi ngakolunye uhlangothi, isinikeza imininingwane emisha ngokuphelele ngezinqubo ezilawula izifundazwe ezinamandla amakhulu kanye namandla azo, namanje. akuqondakali,” kugcizelela umholi wocwaningo uJun. Prof. Carsten Schuck wase-Institute of Physics eMünster University. Ngakho-ke imiphumela ingase ifaneleke ekuthuthukisweni kwezinhlobo ezintsha zobuchwepheshe bekhompyutha. Ucwaningo lushicilelwe ephephabhukwini le-Nature Communications.

Ososayensi basebenzisa ama-superconductors enziwe ngezinto i-yttrium, i-barium, i-copper oxide ne-oxygen, noma i-YBCO ngamafuphi, lapho benza khona izintambo ezincane ze-nanometer. Uma lezi zakhiwo zenza amandla kagesi amanje abonakalayo abizwa ngokuthi 'ama-phase slips' ayenzeka. Esimeni se-YBCO nanowires, ukushintshashintsha kokuminyana kwenkampani yenethiwekhi kubangela ukuhluka ku-supercurrent. Abacwaningi baphenye izinqubo kuma-nanowires emazingeni okushisa angaphansi kuka-20 Kelvin, okuhambisana nokususa ama-253 degrees Celsius. Ngokuhambisana nezibalo zemodeli, babonise ubuningi bezifunda zamandla kuma-nanowires. Izinga lokushisa izintambo ezangena ngalo esimweni se-quantum latholakala ku-12 kuya ku-13 Kelvin—izinga lokushisa eliphindwe izikhathi ezingamakhulu ambalwa kunezinga lokushisa elidingekayo ezintweni ezivame ukusetshenziswa. Lokhu kwenze ososayensi bakwazi ukukhiqiza ama-resonator, okungukuthi amasistimu e-oscillating ashuthelwe kumaza athile, anesikhathi eside sokuphila kanye nokugcina i-quantum mechanical states isikhathi eside. Lokhu kuyimfuneko yokuthuthukiswa kwesikhathi eside kwamakhompiyutha e-quantum amakhulu kakhulu.

Ezinye izingxenye ezibalulekile zokuthuthukiswa kobuchwepheshe be-quantum, kodwa okungenzeka futhi ezokuxilongwa kwezokwelapha, yizitholi ezingabhalisa ngisho nama-photon eyodwa. Iqembu locwaningo likaCarsten Schuck eNyuvesi yaseMünster selineminyaka eminingana lisebenza ekwakheni imitshina enjalo enesithombe esisodwa esekelwe kuma-superconductors. Okuvele kusebenza kahle emazingeni okushisa aphansi, ososayensi emhlabeni wonke bebezama ukufeza ngama-superconductors asezingeni eliphezulu iminyaka engaphezu kweshumi. Ku-YBCO nanowires esetshenziselwa ucwaningo, lo mzamo manje usuphumelele okokuqala ngqa. "Okutholakele kwethu okusha kuvula indlela yezincazelo ezintsha zethiyori nentuthuko yobuchwepheshe engaqinisekiswa ngokuhlolwa," kusho omunye umbhali u-Martin Wolff ovela eqenjini locwaningo lwe-Schuck.

Ungaqiniseka ukuthi abahleli bethu baqaphe ngokucophelela yonke impendulo ethunyelwayo futhi bazothatha izinyathelo ezifanele. Imibono yakho ibalulekile kithi.

Ikheli lakho le-imeyili lisetshenziselwa ukwazisa kuphela umamukeli othumele i-imeyili. Ikheli lakho noma ikheli lomamukeli ngeke lisetshenziselwe enye injongo. Ulwazi olufakayo luzovela emlayezo wakho we-imeyili futhi alugcinwa yi-Phys.org nganoma yiluphi uhlobo.

Thola izibuyekezo zamasonto onke kanye/noma zansuku zonke zilethwe ebhokisini lakho lokungenayo. Ungazikhipha ohlwini noma nini futhi ngeke sabelane ngemininingwane yakho kwabanye abantu.

Le sayithi isebenzisa amakhukhi ukuze ikusize ngokuzulazula, ihlaziye ukusebenzisa kwakho amasevisi ethu, futhi inikeze okuqukethwe okuvela kwabanye abantu. Ngokusebenzisa isayithi lethu, uyavuma ukuthi ufunde futhi waqonda Inqubomgomo yethu Yobumfihlo kanye Nemibandela Yokusebenzisa.
