Helium-3 (He-3) ili ndi zinthu zapadera zomwe zimapangitsa kuti ikhale yofunika kwambiri m'magawo angapo, kuphatikizapo mphamvu ya nyukiliya ndi quantum computing. Ngakhale kuti He-3 ndi yosowa kwambiri ndipo kupanga kwake kumakhala kovuta, ili ndi lonjezo lalikulu la tsogolo la quantum computing. M'nkhaniyi, tikambirana za kupanga He-3 ndi momwe imagwiritsidwira ntchito ngati refrigerant m'makompyuta a quantum.

Kupanga Helium 3

Akuti Helium 3 ilipo pang'ono kwambiri padziko lapansi. Ambiri mwa He-3 padziko lapansi lathu lapansi akuganiziridwa kuti amapangidwa ndi dzuwa ndi nyenyezi zina, ndipo akukhulupiriranso kuti imapezeka pang'ono m'nthaka ya mwezi. Ngakhale kuti He-3 yonse padziko lonse lapansi siidziwika, akuyerekezeredwa kuti imakhala ndi makilogalamu mazana angapo pachaka.

Kupanga He-3 ndi njira yovuta komanso yovuta yomwe imaphatikizapo kulekanitsa He-3 ndi ma isotope ena a helium. Njira yayikulu yopangira ndi kuunikira mpweya wachilengedwe, kupanga He-3 ngati chinthu china. Njirayi ndi yovuta kwambiri, imafuna zida zapadera, ndipo ndi njira yokwera mtengo. Mtengo wopanga He-3 wachepetsa kugwiritsidwa ntchito kwake konse, ndipo ikadali chinthu chosowa komanso chamtengo wapatali.

Kugwiritsa ntchito Helium-3 mu Quantum Computing

Kuwerenga kwa quantum ndi gawo lomwe likutukuka kumene lomwe lingathe kusintha kwambiri mafakitale kuyambira zachuma ndi chisamaliro chaumoyo mpaka kulemba mawu ndi luntha lochita kupanga. Chimodzi mwazovuta zazikulu popanga makompyuta a quantum ndikufunika kosungira firiji kuti iziziritse ma quantum bits (qubits) kufika pa kutentha komwe amagwira ntchito.

He-3 yakhala chisankho chabwino kwambiri choziziritsira ma qubits m'makompyuta a quantum. He-3 ili ndi zinthu zingapo zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito, kuphatikizapo kutentha kwake kochepa, kutentha kwambiri, komanso kuthekera kokhalabe ndi madzi kutentha kochepa. Magulu angapo ofufuza, kuphatikiza gulu la asayansi ku University of Innsbruck ku Austria, awonetsa kugwiritsa ntchito He-3 ngati refrigerant m'makompyuta a quantum. Mu kafukufuku wofalitsidwa mu magazini ya Nature Communications, gululo linawonetsa kuti He-3 ingagwiritsidwe ntchito kuziziritsa ma qubits a purosesa ya quantum yopitilira muyeso mpaka kutentha koyenera, kusonyeza kuti imagwira ntchito bwino ngati quantum computing refrigerant.

Ubwino wa Helium-3 mu Quantum Computing

Pali ubwino wambiri wogwiritsa ntchito He-3 ngati choziziritsira mu kompyuta ya quantum. Choyamba, imapereka malo okhazikika a qubits, kuchepetsa chiopsezo cha zolakwika ndikuwonjezera kudalirika kwa makompyuta a quantum. Izi ndizofunikira kwambiri pankhani ya quantum computing, komwe ngakhale zolakwika zazing'ono zimatha kukhudza kwambiri zotsatira zake.

Chachiwiri, He-3 ili ndi kutentha kochepa kuposa ma refrigerant ena, zomwe zikutanthauza kuti ma qubit amatha kuziziritsidwa kutentha kozizira ndikugwira ntchito bwino. Kuwonjezeka kwa mphamvu kumeneku kungapangitse kuti pakhale kuwerengera mwachangu komanso kolondola, zomwe zimapangitsa He-3 kukhala gawo lofunikira pakupanga makompyuta a quantum.

Pomaliza, He-3 ndi refrigerant yosapsa, yosayaka moto yomwe ndi yotetezeka komanso yosamalira chilengedwe kuposa ma refrigerant ena monga liquid helium. M'dziko lomwe nkhawa za chilengedwe zikukhala zofunika kwambiri, kugwiritsa ntchito He-3 mu quantum computing kumapereka njira ina yobiriwira yomwe imathandiza kuchepetsa mpweya wa carbon womwe umagwiritsidwa ntchito paukadaulo.

Mavuto ndi Tsogolo la Helium-3 mu Quantum Computing

Ngakhale kuti He-3 ili ndi ubwino woonekeratu pakugwiritsa ntchito kwa quantum computing, kupanga ndi kupereka He-3 kukadali vuto lalikulu, ndi zovuta zambiri zaukadaulo, zoyendera komanso zachuma zomwe ziyenera kuthetsedwa. Kupanga He-3 ndi njira yovuta komanso yokwera mtengo, ndipo pali kupezeka kochepa kwa isotope komwe kulipo. Kuphatikiza apo, kunyamula He-3 kuchokera pamalo ake opangira kupita kumalo ake ogwiritsira ntchito ndi ntchito yovuta, zomwe zimapangitsa kuti unyolo wake woperekera zinthu ukhale wovuta kwambiri.

Ngakhale kuti pali mavuto amenewa, ubwino wa He-3 mu quantum computing umapangitsa kuti ikhale ndalama yopindulitsa, ndipo ofufuza ndi makampani akupitiliza kufufuza njira zopangira kupanga kwake ndikugwiritsa ntchito zenizeni. Kupitilizabe kwa He-3 ndi kugwiritsa ntchito kwake mu quantum computing kuli ndi lonjezo la tsogolo la gawo lomwe likukula mofulumirali.
