Zaukadaulo zatsopano zaquantum photodetector

Kachitsulo kakang'ono kwambiri padziko lapansi ka silicon chip quantumPhotodetector

Posachedwapa, gulu lofufuza ku United Kingdom lachita bwino kwambiri pakupanga ukadaulo wocheperako wa quantum, adaphatikiza bwino kachipangizo kakang'ono kwambiri padziko lonse lapansi ka quantum photodetector mu silicon chip. Ntchitoyi, yotchedwa "A Bi-CMOS electronic photonic integrated circuit quantum light detector," idasindikizidwa mu Science Advances. M'zaka za m'ma 1960, asayansi ndi mainjiniya adayamba kupanga ma transistors ang'onoang'ono kukhala ma microchips otsika mtengo, luso lomwe linayambitsa nthawi ya chidziwitso. Tsopano, asayansi awonetsa kwa nthawi yoyamba kuphatikiza kwa quantum photodetectors woonda kuposa tsitsi la munthu pa silicon chip, kutibweretsa ife sitepe imodzi pafupi ndi nthawi yaukadaulo wa quantum yomwe imagwiritsa ntchito kuwala. Kuzindikira m'badwo wotsatira waukadaulo wazidziwitso, kupanga kwakukulu kwa zida zamagetsi zamagetsi ndi zithunzi ndizo maziko. Kupanga ukadaulo wa quantum m'malo azamalonda omwe alipo ndizovuta zomwe zikuchitika pa kafukufuku wamayunivesite ndi makampani padziko lonse lapansi. Kutha kupanga zida zamtundu wapamwamba kwambiri pamlingo waukulu ndikofunikira pakompyuta ya quantum, chifukwa ngakhale kupanga komputa ya quantum kumafuna zigawo zambiri.

Ofufuza ku United Kingdom awonetsa quantum photodetector yokhala ndi dera lophatikizika la ma microns 80 okha ndi ma microns 220. Kukula kochepa kotereku kumapangitsa kuti ma quantum photodetectors akhale othamanga kwambiri, omwe ndi ofunikira kuti atsegule mwachangu.quantum communicationndikuthandizira kuthamanga kwambiri kwa makompyuta a optical quantum. Kugwiritsa ntchito njira zopangira zokhazikika komanso zopezeka pazamalonda kumathandizira kugwiritsa ntchito koyambirira kumadera ena aukadaulo monga kumva ndi kulumikizana. Zowunikira zotere zimagwiritsidwa ntchito m'njira zosiyanasiyana mu quantum optics, zimatha kugwira ntchito kutentha kwa chipinda, ndipo ndizoyenera kulumikizana ndi ma quantum, masensa ovuta kwambiri monga zowunikira zamakono zokokera mafunde, komanso kupanga ma quantum ena. makompyuta.

Ngakhale kuti zodziwira izi ndizofulumira komanso zazing'ono, zimakhalanso zovuta kwambiri. Chinsinsi choyezera kuwala kwa quantum ndikukhudzidwa ndi phokoso la quantum. Makina a Quantum amapanga phokoso laling'ono, loyambira pamakina onse a kuwala. Khalidwe la phokosoli limasonyeza zambiri za mtundu wa kuwala kwa quantum komwe kumaperekedwa mu dongosolo, kungathe kudziwa kukhudzidwa kwa optical sensor, ndipo kungagwiritsidwe ntchito pomanganso masamu a quantum state. Kafukufukuyu adawonetsa kuti kupanga detector ya optical kukhala yaying'ono komanso yofulumira sikunalepheretse chidwi chake pakuyesa kuchuluka kwa mayiko. M'tsogolomu, ofufuzawo akukonzekera kuphatikizira zida zina zosokoneza ukadaulo wa quantum ku chip scale, kupititsa patsogolo luso la zatsopano.chowunikira chowunikira, ndikuyesani m'njira zosiyanasiyana. Kuti chowunikiracho chipezeke kwambiri, gulu lofufuza lidachipanga pogwiritsa ntchito akasupe omwe amapezeka pamalonda. Komabe, gululi likugogomezera kuti ndikofunikira kuti tipitirizebe kuthana ndi zovuta za kupanga scalable ndi teknoloji ya quantum. Popanda kuwonetsa kupanga kowonjezereka kwa quantum hardware, zotsatira ndi ubwino wa teknoloji ya quantum zidzachedwa ndi zochepa. Kupambana uku ndi gawo lofunikira pakukwaniritsa ntchito zazikulu zateknoloji ya quantum, ndipo tsogolo la quantum computing ndi quantum communication lili ndi zotheka zopanda malire.
