Ubushakashatsi bushya bwakorewe muri kaminuza ya Chicago na kaminuza ya Shanxi bwavumbuye uburyo bwo kwigana imbaraga zidasanzwe hakoreshejwe urumuri rwa laser. Superconductivity ibaho mugihe impapuro ebyiri za graphene zigoretse gato nkuko zishyizwe hamwe. Ubuhanga bwabo bushya bwakoreshwa mugusobanukirwa neza imyitwarire yibikoresho kandi birashobora gukingura inzira ya tekinoroji ya kwant cyangwa ibikoresho bya elegitoroniki. Ibisubizo bijyanye nubushakashatsi biherutse gusohoka mu kinyamakuru Kamere.
Imyaka ine irashize, abashakashatsi bo muri MIT bakoze ikintu gitangaje: Niba impapuro zisanzwe za atome ya karubone zigoramye uko zegeranye, zirashobora guhinduka mumashanyarazi. Ibikoresho bidasanzwe nka "superconductor" bifite ubushobozi bwihariye bwo kohereza ingufu zitagira inenge. Amashanyarazi nayo niyo shingiro ryamashusho ya magnetiki resonance yerekana amashusho, kuburyo abahanga naba injeniyeri bashobora kubona byinshi kubakoresha. Ariko, bafite ibibi byinshi, nko gusaba gukonja munsi ya zeru kugirango ikore neza. Abashakashatsi bemeza ko niba basobanukiwe neza na fiziki n'ingaruka, bashobora guteza imbere imiyoboro mishya kandi bagafungura uburyo butandukanye bw'ikoranabuhanga. Laboratwari ya Chin hamwe nitsinda ryubushakashatsi bwa kaminuza ya Shanxi babanje kuvumbura uburyo bwo kwigana ibikoresho bya kwant bigoye ukoresheje atome ikonje na laseri kugirango byoroshye kubisesengura. Hagati aho, bizeye gukora kimwe na sisitemu ya bilayeri. Itsinda ry’ubushakashatsi n’abahanga bo muri kaminuza ya Shanxi bakoze uburyo bushya bwo "kwigana" utwo tuntu twagoramye. Nyuma yo gukonjesha atome, bakoresheje laser kugirango bategure atome ya rubidium mubice bibiri, bishyizwe hejuru yundi. Abahanga baca bakoresha microwave kugirango borohereze imikoranire hagati ya latike zombi. Biragaragara ko bombi bakorana neza. Ibice birashobora kunyura mubikoresho bitagabanijwe no guterana amagambo, bitewe nikintu kizwi nka "superfluidity", gisa na superconductivity. Ubushobozi bwa sisitemu yo guhindura icyerekezo cya latike ebyiri zatumye abashakashatsi bamenya ubwoko bushya bwa superfluid muri atome. Abashakashatsi basanze bashobora guhuza imbaraga z’imikoranire ya za latike zombi mu guhindura ubukana bwa microwave, kandi bashobora kuzunguruka utwo tubiri tubiri na lazeri nta mbaraga nyinshi - bigatuma iba uburyo bworoshye. Kurugero, niba umushakashatsi ashaka gukora ubushakashatsi burenze ibice bibiri kugeza kuri bitatu cyangwa bine, ibice byasobanuwe haruguru byoroshe kubikora. Igihe cyose umuntu avumbuye superconductor nshya, isi ya fiziki ireba hejuru. Ariko iki gihe ibisubizo birashimishije cyane kuko bishingiye kubintu byoroshye kandi bisanzwe nka graphene.
