Ubuchwepheshe obusha be-i-quantum photodetector

I-quantum encane kunazo zonke emhlabeni ye-silicon chipumshini wokuthola izithombe

Muva nje, ithimba labacwaningi e-United Kingdom lenze intuthuko ebalulekile ekuncishisweni kobuchwepheshe be-quantum, bahlanganise ngempumelelo i-photodetector encane kunazo zonke emhlabeni ye-quantum emhlabeni ibe yi-silicon chip. Lo msebenzi, onesihloko esithi “A Bi-CMOS electronic photonic integrated circuit quantum light detector,” ushicilelwe ku-Science Advances. Ngawo-1960, ososayensi nonjiniyela baqala ukufaka ama-transistors amancane kuma-microchip ashibhile, okuwukusungula okusha okwaletha inkathi yolwazi. Manje, ososayensi babonise okokuqala ukuhlanganiswa kwama-photodetector e-quantum amancane kunezinwele zomuntu kwi-silicon chip, okusisondeza enkathini yobuchwepheshe be-quantum obusebenzisa ukukhanya. Ukuze kuqashelwe isizukulwane esilandelayo sobuchwepheshe bolwazi obuthuthukisiwe, ukukhiqizwa okukhulu kwemishini ye-electronic kanye ne-photonic esebenza kahle kakhulu kuyisisekelo. Ukukhiqiza ubuchwepheshe be-quantum ezindaweni zezentengiselwano ezikhona kuyinselele eqhubekayo yocwaningo lwaseyunivesithi kanye nezinkampani emhlabeni jikelele. Ukukwazi ukukhiqiza ihadiwe ye-quantum esebenza kahle kakhulu ngezinga elikhulu kubalulekile kwi-quantum computing, ngoba ngisho nokwakha ikhompyutha ye-quantum kudinga inani elikhulu lezingxenye.

Abacwaningi e-United Kingdom babonise i-quantum photodetector enendawo yesekethe ehlanganisiwe engama-micron angu-80 kuphela ngama-micron angu-220. Usayizi omncane kangaka uvumela ama-quantum photodetector ukuba asheshe kakhulu, okuyinto ebalulekile ekuvuleni isivinini esikhulu.ukuxhumana kwe-quantumkanye nokuvumela ukusebenza okusheshayo kwamakhompyutha e-optical quantum. Ukusebenzisa amasu okukhiqiza asevele ekhona futhi atholakala kwezentengiselwano kwenza kube lula ukusetshenziswa kwasekuqaleni kwezinye izindawo zobuchwepheshe ezifana nokuzwa nokuxhumana. Ama-detector anjalo asetshenziswa ezinhlobonhlobo zezicelo kuma-quantum optics, angasebenza ekushiseni kwegumbi, futhi afanelekela ukuxhumana kwe-quantum, izinzwa ezibucayi kakhulu njengezinzwa zamagagasi adonsela phansi ezisezingeni eliphezulu, kanye nasekuklanyweni kwamakhompyutha athile e-quantum.

Nakuba la ma-detector eshesha futhi emancane, nawo ayazwela kakhulu. Isihluthulelo sokulinganisa ukukhanya kwe-quantum ukuzwela komsindo we-quantum. I-Quantum mechanics ikhiqiza amazinga amancane, ayisisekelo omsindo kuzo zonke izinhlelo ze-optical. Ukuziphatha kwalo msindo kwembula ulwazi mayelana nohlobo lokukhanya kwe-quantum oludluliselwa ohlelweni, kunganquma ukuzwela kwenzwa ye-optical, futhi kungasetshenziswa ukwakha kabusha ngokwezibalo isimo se-quantum. Ucwaningo lukhombisile ukuthi ukwenza i-optical detector ibe ncane futhi isheshe akuzange kuvimbele ukuzwela kwayo ekulinganiseni izimo ze-quantum. Esikhathini esizayo, abacwaningi bahlela ukuhlanganisa ezinye ihadiwe yobuchwepheshe be-quantum ephazamisayo esikalini se-chip, bathuthukise ukusebenza kahle kwentsha.isitholi sokubona, futhi uyihlole ezinhlotsheni ezahlukene zezicelo. Ukuze kwenziwe i-detector itholakale kabanzi, ithimba locwaningo layikhiqiza kusetshenziswa ama-founters atholakala kwezentengiselwano. Kodwa-ke, ithimba ligcizelela ukuthi kubalulekile ukuqhubeka nokubhekana nezinselele zokukhiqiza okunwebekayo ngobuchwepheshe be-quantum. Ngaphandle kokubonisa ukukhiqizwa kwehadiwe ye-quantum okunwebekayo ngempela, umthelela kanye nezinzuzo zobuchwepheshe be-quantum kuzobambezeleka futhi kunqunyelwe. Lokhu kuphumelela kuphawula isinyathelo esibalulekile ekufinyeleleni ukusetshenziswa okukhulu kwe-ubuchwepheshe be-quantum, futhi ikusasa lokubala kwe-quantum kanye nokuxhumana kwe-quantum ligcwele amathuba angenamkhawulo.
