Ukadaulo watsopano wa chowunikira zithunzi cha quantum

Ukadaulo watsopano wachowunikira zithunzi cha quantum

Chidutswa chaching'ono kwambiri cha silicon chip padziko lonse lapansichowunikira zithunzi

Posachedwapa, gulu lofufuza ku United Kingdom lapanga chitukuko chofunikira kwambiri pakuchepetsa ukadaulo wa quantum, ndipo laphatikiza bwino chowunikira chaching'ono kwambiri padziko lonse lapansi cha quantum mu silicon chip. Ntchitoyi, yotchedwa "A Bi-CMOS electronic photonic integrated circuit quantum light detector," yafalitsidwa mu Science Advances. M'zaka za m'ma 1960, asayansi ndi mainjiniya adayika ma transistors ang'onoang'ono pa ma microchip otsika mtengo, luso lomwe linayambitsa nthawi ya chidziwitso. Tsopano, asayansi awonetsa koyamba kuphatikiza kwa zowunikira za quantum zoonda kuposa tsitsi la munthu pa silicon chip, zomwe zikutibweretsa pafupi ndi nthawi yaukadaulo wa quantum womwe umagwiritsa ntchito kuwala. Kuti tikwaniritse mbadwo wotsatira waukadaulo wapamwamba wazidziwitso, kupanga kwakukulu kwa zida zamagetsi ndi za photonic zomwe zimagwira ntchito bwino ndiye maziko. Kupanga ukadaulo wa quantum m'malo ogulitsa omwe alipo ndi vuto lomwe likupitilira kwa kafukufuku wa mayunivesite ndi makampani padziko lonse lapansi. Kutha kupanga zida zapamwamba za quantum pamlingo waukulu ndikofunikira kwambiri pakompyuta ya quantum, chifukwa ngakhale kupanga kompyuta ya quantum kumafuna zigawo zambiri.

Ofufuza ku United Kingdom awonetsa chipangizo chowunikira zithunzi cha quantum chokhala ndi dera lozungulira lokhala ndi ma microns 80 okha ndi ma microns 220. Kukula kochepa koteroko kumalola kuti zida zowunikira zithunzi za quantum zikhale zachangu kwambiri, zomwe ndizofunikira kwambiri kuti zitsegule liwiro lapamwamba.kulankhulana kwa quantumkomanso kulola kuti makompyuta a quantum agwiritsidwe ntchito mwachangu kwambiri. Kugwiritsa ntchito njira zopangira zomwe zakhazikitsidwa kale komanso zomwe zikupezeka m'masitolo kumathandiza kugwiritsa ntchito koyambirira m'magawo ena aukadaulo monga kuzindikira ndi kulumikizana. Zipangizo zoyesera zoterezi zimagwiritsidwa ntchito m'njira zosiyanasiyana mu quantum optics, zimatha kugwira ntchito kutentha kwa chipinda, ndipo ndizoyenera kulumikizana ndi quantum, masensa ozindikira kwambiri monga zowunikira mafunde amphamvu yokoka, komanso popanga makompyuta ena a quantum.

Ngakhale kuti zowunikira izi ndi zachangu komanso zazing'ono, zimakhalanso zomvera kwambiri. Chinsinsi choyezera kuwala kwa quantum ndi kukhudzidwa ndi phokoso la quantum. Makina a quantum amapanga phokoso laling'ono, loyambira m'makina onse owonera. Khalidwe la phokosoli limavumbula zambiri zokhudza mtundu wa kuwala kwa quantum komwe kumatumizidwa mu dongosololi, kumatha kudziwa kukhudzidwa kwa sensa ya optical, ndipo kungagwiritsidwe ntchito kukonzanso momwe quantum ilili mwamasamu. Kafukufukuyu adawonetsa kuti kupanga chowunikira cha optical kukhala chaching'ono komanso chofulumira sikunalepheretse kukhudzidwa kwake ndi kuyeza quantum states. M'tsogolomu, ofufuza akukonzekera kuphatikiza zida zina zosokoneza ukadaulo wa quantum ku chilinganizo cha chip, ndikupititsa patsogolo magwiridwe antchito atsopano.chowunikira cha kuwala, ndikuyesa m'njira zosiyanasiyana. Kuti chipangizo chowunikira chipezeke mosavuta, gulu lofufuza linachipanga pogwiritsa ntchito ma founters omwe amapezeka m'masitolo. Komabe, gululo likugogomezera kuti ndikofunikira kupitiliza kuthana ndi mavuto opanga zinthu zokulira pogwiritsa ntchito ukadaulo wa quantum. Popanda kuwonetsa kupanga zida za quantum zokulira, zotsatira ndi zabwino za ukadaulo wa quantum zidzachedwa komanso zochepa. Kupambana kumeneku ndi sitepe yofunika kwambiri pakukwaniritsa kugwiritsa ntchito kwakukulu kwaukadaulo wa kwantumu, ndipo tsogolo la quantum computing ndi quantum communication lili ndi mwayi wochuluka.
