Uphononongo olutsha oluvela kwiYunivesithi yaseChicago kunye neYunivesithi yaseShanxi lufumene indlela yokulinganisa i-superconductivity usebenzisa ukukhanya kwe-laser. I-Superconductivity yenzeke xa amaphepha amabini egraphene ejijwa kancinane njengoko ebekwe kunye. Ubuchule babo obutsha bunokusetyenziselwa ukuqonda ngcono indlela yokuziphatha kwemathiriyeli kwaye kunokuvula indlela yetekhnoloji yequantum yexesha elizayo okanye i-elektroniki. Iziphumo zophando ezifanelekileyo zisanda kupapashwa kwijenali yeNdalo.

Kwiminyaka emine eyadlulayo, abaphandi baseMIT bafumanisa into eyothusayo: Ukuba amaphepha aqhelekileyo e-athomu yekhabhoni ajijekile njengoko apakishwe, anokuguqulwa abe zii-superconductors. Izinto ezinqabileyo ezifana ne "superconductors" zinekhono elilodwa lokuhambisa amandla ngokungenasiphako. Ii-Superconductors zikwasisiseko sokucinga ngemagnethi yangoku, ngoko ke izazinzulu kunye neenjineli zinokuzifumana iindlela ezininzi zokuzisebenzisa. Nangona kunjalo, banezinto ezininzi ezingalunganga, ezifana nokufuna ukupholisa ngaphantsi kwe-zero ngokupheleleyo ukuze kusebenze ngokufanelekileyo. Abaphandi bakholelwa ukuba ukuba bayayiqonda ngokupheleleyo i-physics kunye nemiphumo, banokuphuhlisa ii-superconductors ezintsha kwaye bavule amathuba ahlukeneyo eteknoloji. Ilebhu kaChin kunye neqela lophando leDyunivesithi yaseShanxi ngaphambili baqulunqe iindlela zokuphindaphinda izinto ezintsonkothileyo zequantum zisebenzisa iiathom ezipholileyo kunye nelases ukuze kube lula ukuzihlalutya. Okwangoku, banethemba lokwenza okufanayo ngenkqubo yebilayer ejijekileyo. Ngoko ke, iqela lophando kunye noososayensi abavela kwiYunivesithi yaseShanxi baphuhlise indlela entsha "yokulinganisa" ezi zixhobo zijijekileyo. Emva kokupholisa iiathom, basebenzisa i<em>laser ukuze balungelelanise iiathom zerubidium zibe ngamagumbi amabini abekwe phezu kwenye. Izazinzulu emva koko zasebenzisa ii-microwaves ukuququzelela intsebenziswano phakathi kweelathisi ezimbini. Kuyavela ukuba bobabini basebenzisana kakuhle. Amacandelo angakwazi ukuhamba kwizinto ngaphandle kokunciphisa ukungqubuzana, ngenxa yento eyaziwa ngokuba yi "superfluidity," efana ne-superconductivity. Ukukwazi kwesistim ukuguqula i-twist orientation ye-lattices ezimbini kwavumela abaphandi ukuba babone uhlobo olutsha lwe-superfluid kwii-athomu. Abaphandi bafumanise ukuba banokutshintsha amandla onxibelelwano lwee-lattices ezimbini ngokutshintsha ubukhulu bee-microwaves, kwaye banokujikelezisa iileyile ezimbini ngelaser ngaphandle komzamo omkhulu - beyenza ibe yinkqubo ebhetyebhetye ngokumangalisayo. Umzekelo, ukuba umphandi ufuna ukuphonononga ngaphaya kwezibini ukuya kwezintathu okanye ezine umaleko, ukuseta okuchazwe ngasentla kwenza kube lula ukwenza njalo. Ngalo lonke ixesha umntu efumana i-superconductor entsha, umhlaba wefiziksi ujonge phezulu ngokuncoma. Kodwa ngeli xesha isiphumo sisonwabisa ngakumbi kuba sisekwe kwizinto ezilula neziqhelekileyo njengegraphene.
