Mafi ƙarancin guntun silicon a duniyana'urar gano hoto

Kwanan nan, wata ƙungiyar bincike a Burtaniya ta yi wani muhimmin ci gaba a fannin rage girman fasahar kwantum, inda suka yi nasarar haɗa ƙaramin na'urar gano kwantum a duniya cikin guntun silicon. An buga aikin, mai taken "A Bi-CMOS electronic photonic integrated circuit quantum light detector," a cikin Science Advances. A shekarun 1960, masana kimiyya da injiniyoyi sun fara rage girman transistor zuwa ƙananan na'urori masu araha, wani sabon abu da ya kawo zamanin bayanai. Yanzu, masana kimiyya sun fara nuna haɗakar na'urorin gano kwantum sirara fiye da gashin ɗan adam zuwa guntun silicon, wanda ya kawo mu mataki ɗaya kusa da zamanin fasahar kwantum wanda ke amfani da haske. Don cimma ƙarni na gaba na fasahar bayanai mai ci gaba, kera kayan aikin lantarki da na'urorin photonic masu aiki sosai shine tushe. Kera fasahar kwantum a wuraren kasuwanci da ake da su ƙalubale ne da ke ci gaba da gudana ga bincike na jami'o'i da kamfanoni a duk faɗin duniya. Samun damar kera kayan aikin tantance kwantum masu aiki sosai a babban sikelin yana da mahimmanci ga ƙididdigar kwantum, saboda ko da gina kwamfutar kwantum yana buƙatar adadi mai yawa na kayan aiki.

Masu bincike a Burtaniya sun nuna na'urar gano ƙwayoyin halitta mai siffar kwantum mai girman microns 80 kawai da microns 220. Irin wannan ƙaramin girman yana bawa na'urorin gano ƙwayoyin halitta damar yin sauri sosai, wanda yake da mahimmanci don buɗe manyan na'urori masu sauri.sadarwar kwantumda kuma ba da damar yin amfani da kwamfutocin kwantum mai saurin gaske. Amfani da dabarun kera kayayyaki da aka kafa kuma waɗanda ake da su a kasuwa yana sauƙaƙa amfani da su da wuri zuwa wasu fannoni na fasaha kamar ji da sadarwa. Ana amfani da irin waɗannan na'urorin gano abubuwa a cikin aikace-aikace iri-iri a cikin na'urorin hangen nesa na kwantum, suna iya aiki a zafin ɗaki, kuma sun dace da sadarwa ta kwantum, na'urori masu auna firikwensin masu matuƙar tasiri kamar na'urorin gano raƙuman nauyi na zamani, da kuma ƙirar wasu kwamfutocin kwantum.

Duk da cewa waɗannan na'urorin ganowa suna da sauri da ƙanana, suna da matuƙar saurin amsawa. Mabuɗin auna hasken kwantum shine ƙarfin amsawa ga hayaniyar kwantum. Makanikan kwantum suna samar da ƙananan matakan hayaniya na asali a cikin dukkan tsarin gani. Halayyar wannan hayaniyar tana bayyana bayanai game da nau'in hasken kwantum da ake watsawa a cikin tsarin, yana iya tantance ƙarfin amsawar na'urar hangen nesa, kuma ana iya amfani da shi don sake gina yanayin kwantum ta hanyar lissafi. Binciken ya nuna cewa sanya na'urar gano haske ƙarami da sauri bai hana shi jin daɗin auna yanayin kwantum ba. A nan gaba, masu binciken suna shirin haɗa sauran kayan aikin fasahar kwantum masu rikitarwa zuwa sikelin guntu, ƙara inganta ingancin sabon na'urarna'urar gano gani, kuma a gwada shi ta hanyoyi daban-daban. Domin samar da na'urar gano ...fasahar kwantum, kuma makomar kwamfutocin kwantum da sadarwa ta kwantum cike take da damarmaki marasa iyaka.
