Kupanga makompyuta a quantum omwe amatha kuthetsa mavuto, omwe makompyuta akale amatha kuthetsa ndi khama lalikulu kapena ayi - ichi ndi cholinga chomwe chikutsatiridwa ndi chiwerengero chochulukira cha magulu ofufuza padziko lonse lapansi. Chifukwa: Zotsatira za Quantum, zomwe zimachokera kudziko la tinthu tating'onoting'ono ndi zomangira, zimalola kugwiritsa ntchito ukadaulo watsopano. Zomwe zimatchedwa superconductors, zomwe zimalola kuti zidziwitso ndi ma signature malinga ndi malamulo a quantum mechanics, zimatengedwa ngati zigawo zolonjeza kuti zizindikire makompyuta a quantum. Mfundo yomamatira ya superconducting nanostructures, komabe, ndi yakuti amangogwira ntchito pamtunda wotsika kwambiri ndipo motero ndi ovuta kubweretsa ntchito zothandiza. googletag.cmd.push(function() {googletag.display('div-gpt-ad-1449240174198-2′);});
Ofufuza pa yunivesite ya Münster ndi Forschungszentrum Jülich tsopano, kwa nthawi yoyamba, adawonetsa zomwe zimadziwika kuti mphamvu quantization mu nanowires zopangidwa ndi superconductors zotentha kwambiri - mwachitsanzo, ma superconductors, momwe kutentha kumakwera pansi komwe kumayendera ma quantum mechanical. Superconducting nanowire ndiye imangotengera mphamvu zosankhidwa zokha zomwe zingagwiritsidwe ntchito kulembera zidziwitso. Mu superconductors kutentha kwambiri, ochita kafukufuku adathanso kuyang'ana kwa nthawi yoyamba kuyamwa kwa photon imodzi, tinthu tating'onoting'ono tomwe timatumiza uthenga.
"Kumbali imodzi, zotsatira zathu zitha kuthandizira kugwiritsa ntchito ukadaulo wosavuta wozizira kwambiri muukadaulo wa quantum m'tsogolomu, ndipo kumbali ina, zimatipatsa chidziwitso chatsopano panjira zomwe zimayang'anira mayiko a superconducting ndi mphamvu zawo, zomwe zikadalipobe. osamvetsetseka,” akutsindika motero mtsogoleri wa kafukufukuyu Jun. Prof. Carsten Schuck wa ku Institute of Physics pa yunivesite ya Münster. Zotsatira zake zingakhale zofunikira pakupanga mitundu yatsopano yaukadaulo wamakompyuta. Kafukufukuyu adasindikizidwa mu nyuzipepala ya Nature Communications.
Asayansi adagwiritsa ntchito ma superconductors opangidwa ndi zinthu yttrium, barium, copper oxide ndi oxygen, kapena YBCO mwachidule, pomwe adapanga mawaya ochepa a nanometer. Mapangidwewa akamayendetsa mphamvu zamagetsi zomwe zimatchedwa 'phase slips' zimachitika. Pankhani ya YBCO nanowires, kusinthasintha kwa kachulukidwe kacharge carriers kumayambitsa kusiyanasiyana kwa supercurrent. Ofufuzawo adafufuza njira za nanowires pa kutentha kosachepera 20 Kelvin, komwe kumafanana ndi madigiri 253 Celsius. Kuphatikiza ndi kuwerengera kwachitsanzo, adawonetsa kuchuluka kwa mphamvu zamagetsi mu nanowires. Kutentha kumene mawayawo analowa m’chigawo cha quantum kunapezeka pa 12 mpaka 13 Kelvin—kutentha kuŵirikiza mazana angapo kuposa kutentha kofunikira pa zipangizo zogwiritsiridwa ntchito nthaŵi zonse. Izi zinathandiza asayansi kupanga ma resonator, mwachitsanzo, makina ozungulira omwe amayendera ma frequency enieni, okhala ndi moyo wautali komanso kusunga ma quantum mechanical states kwautali. Ichi ndi chofunikira pakupanga kwanthawi yayitali kwamakompyuta ochulukirachulukira.
Zinanso zofunika pakupanga matekinoloje a quantum, komanso mwinanso zowunikira zamankhwala, ndi zowunikira zomwe zimatha kulembetsa ngakhale mafotoni amodzi. Gulu lofufuza la Carsten Schuck ku Yunivesite ya Münster lakhala likugwira ntchito kwa zaka zingapo popanga zowunikira zamtundu umodzi zotengera ma superconductors. Zomwe zimagwira ntchito bwino pa kutentha kochepa, asayansi padziko lonse lapansi akhala akuyesera kuti akwaniritse ndi ma superconductors apamwamba kwambiri kwa zaka zoposa khumi. Mu ma YBCO nanowires omwe amagwiritsidwa ntchito pophunzira, kuyesa uku kwapambana kwa nthawi yoyamba. "Zomwe tapeza zatsopano zimatsegulira njira zofotokozera zatsopano zotsimikiziridwa ndiukadaulo," akutero wolemba mnzake Martin Wolff wa gulu lofufuza la Schuck.
Mutha kutsimikiziridwa kuti akonzi athu amayang'anitsitsa ndemanga zonse zomwe zatumizidwa ndipo adzachitapo kanthu. Malingaliro anu ndi ofunikira kwa ife.
Imelo yanu imagwiritsidwa ntchito podziwitsa wolandirayo amene watumiza imeloyo. Adilesi yanu kapena adilesi ya wolandila sizigwiritsidwa ntchito pazifukwa zina zilizonse. Zomwe mumalemba ziziwoneka mu imelo yanu ndipo sizisungidwa ndi Phys.org mwanjira iliyonse.
Pezani zosintha zapamlungu ndi/kapena zatsiku ndi tsiku zimatumizidwa ku bokosi lanu. Mutha kusiya kulembetsa nthawi iliyonse ndipo sitidzagawana zambiri zanu ndi ena.
Tsambali limagwiritsa ntchito makeke kukuthandizani kuyenda, kusanthula momwe mumagwiritsira ntchito ntchito zathu, ndikupereka zomwe zili kuchokera kwa ena. Pogwiritsa ntchito tsamba lathu, mumavomereza kuti mwawerenga ndikumvetsetsa Mfundo Zazinsinsi ndi Migwirizano yathu.
