Ubuchwepheshe obusha bei-quantum photodetector
I-silicon chip quantum encane kunazo zonke emhlabenii-photodetector
Muva nje, ithimba labacwaningi e-United Kingdom lenze impumelelo ebalulekile ekwenzeni kancane kobuchwepheshe be-quantum, bahlanganise ngempumelelo i-quantum photodetector encane kunazo zonke emhlabeni ibe yi-silicon chip. Umsebenzi, onesihloko esithi “A Bi-CMOS electronic photonic integrated circuit quantum light detector,” ushicilelwe ku-Science Advances. Ngawo-1960, ososayensi nonjiniyela baqala ukwenza ama-transistors amancane kuma-microchips ashibhile, into entsha eyangenisa inkathi yolwazi. Manje, ososayensi baye babonisa okokuqala ukuhlanganiswa kwe-quantum photodetectors mncane kunezinwele zomuntu ku-silicon chip, okusiletha isinyathelo esisodwa enkathini yobuchwepheshe be-quantum esebenzisa ukukhanya. Ukuze uthole isizukulwane esilandelayo sobuchwepheshe bolwazi obuthuthukile, ukukhiqizwa okukhulu kwemishini kagesi neyezithombe kuyisisekelo. Ukukhiqiza ubuchwepheshe be-quantum ezindaweni zokuhweba ezikhona kuyinselelo eqhubekayo yocwaningo lwamanyuvesi nezinkampani emhlabeni jikelele. Ukwazi ukwenza i-hardware ye-quantum esebenza kakhulu ngezinga elikhulu kubalulekile ku-quantum computing, ngoba ngisho nokwakha ikhompuyutha ye-quantum kudinga inani elikhulu lezingxenye.
Abacwaningi base-United Kingdom babonise i-quantum photodetector enendawo ehlanganisiwe yesekethe yama-microns angama-80 ngama-microns angama-220. Usayizi omncane kangako uvumela ama-photodetectors we-quantum ukuthi asheshe kakhulu, okubalulekile ekuvuleni ngesivinini esikhulu.ukuxhumana kwe-quantumkanye nokuvumela ukusebenza ngesivinini esiphezulu kwamakhompiyutha e-optical quantum. Ukusebenzisa amasu okukhiqiza asunguliwe futhi atholakala ngokwentengiso kusiza ukusetshenziswa kusenesikhathi kwezinye izindawo zobuchwepheshe ezifana nokuzwa nokuxhumana. Imitshina enjalo isetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ku-quantum optics, ingasebenza ekamelweni lokushisa, futhi ifanele ukuxhumana kwe-quantum, izinzwa ezizwela kakhulu njenge-state-of-the-art gravitational wave detectors, kanye nasekuklanyweni kwe-quantum ethile. amakhompyutha.
Nakuba le mitshina ishesha futhi incane, ibuye ibe bucayi kakhulu. Isihluthulelo sokulinganisa ukukhanya kwe-quantum ukuzwela kumsindo we-quantum. I-Quantum mechanics ikhiqiza amazinga amancane, ayisisekelo womsindo kuzo zonke izinhlelo zokubona. Ukuziphatha kwalo msindo kuveza ulwazi mayelana nohlobo lokukhanya kwe-quantum okudluliselwa ohlelweni, kunganquma ukuzwela kwenzwa yokubona, futhi kungasetshenziswa ukuze kwakhiwe kabusha ngokwezibalo isimo se-quantum. Ucwaningo lubonise ukuthi ukwenza umtshina we-optical ube mncane futhi usheshe akuzange kuvimbe ukuzwela kwawo ekulinganiseni izifunda ze-quantum. Ngokuzayo, abacwaningi bahlela ukuhlanganisa enye i-hardware yobuchwepheshe be-quantum ephazamisayo esikalini se-chip, bathuthukise ukusebenza kahle kwentsha.umtshina optical, futhi uyihlole kuzinhlelo zokusebenza ezihlukene. Ukwenza umtshina utholakale kabanzi, ithimba labacwaningi uwenze kusetshenziswa imithombo etholakalayo ethengiswayo. Kodwa-ke, ithimba ligcizelela ukuthi kubalulekile ukuqhubeka nokubhekana nezinselele zokukhiqiza okunoshukela ngobuchwepheshe be-quantum. Ngaphandle kokubonisa ukukhiqizwa kwezingxenyekazi zekhompuyutha ze-quantum ezingaka ngempela, umthelela kanye nezinzuzo zobuchwepheshe be-quantum zizobambezeleka futhi zibe nomkhawulo. Lokhu kuphumelela kubonisa isinyathelo esibalulekile ekufezeni izicelo ezinkuluubuchwepheshe be-quantum, kanye nekusasa le-quantum computing kanye nokuxhumana kwe-quantum kugcwele amathuba angapheli.
