Lub ntiaj teb me tshaj plaws silicon chip quantumlub tshuab ntes duab

Tsis ntev los no, ib pab pawg tshawb fawb hauv tebchaws United Kingdom tau ua tiav qhov kev tshawb pom tseem ceeb hauv kev ua kom me me ntawm cov thev naus laus zis quantum, lawv tau ua tiav kev koom ua ke lub ntiaj teb me tshaj plaws quantum photodetector rau hauv lub silicon chip. Cov haujlwm, hu ua "A Bi-CMOS electronic photonic integrated circuit quantum light detector," tau luam tawm hauv Science Advances. Xyoo 1960, cov kws tshawb fawb thiab cov engineers tau ua thawj zaug miniaturized transistors rau ntawm cov microchips pheej yig, ib qho kev tsim kho tshiab uas coj mus rau hauv lub hnub nyoog ntaub ntawv. Tam sim no, cov kws tshawb fawb tau ua thawj zaug qhia txog kev koom ua ke ntawm quantum photodetectors nyias dua li cov plaub hau tib neeg rau ntawm lub silicon chip, coj peb ib kauj ruam ze rau lub sijhawm ntawm quantum technology uas siv lub teeb. Txhawm rau kom paub txog tiam tom ntej ntawm cov thev naus laus zis siab heev, kev tsim khoom loj ntawm cov khoom siv hluav taws xob thiab photonic ua tau zoo yog lub hauv paus. Kev tsim cov thev naus laus zis quantum hauv cov chaw lag luam uas twb muaj lawm yog qhov kev sib tw tas mus li rau kev tshawb fawb hauv tsev kawm qib siab thiab cov tuam txhab thoob ntiaj teb. Kev muaj peev xwm tsim cov khoom siv quantum ua tau zoo ntawm qhov loj yog qhov tseem ceeb rau kev suav lej quantum, vim tias txawm tias tsim lub khoos phis tawj quantum xav tau ntau yam khoom.

Cov kws tshawb fawb hauv tebchaws United Kingdom tau ua qauv qhia txog lub tshuab quantum photodetector nrog thaj tsam integrated circuit ntawm tsuas yog 80 microns los ntawm 220 microns. Qhov me me no ua rau cov tshuab quantum photodetectors ua haujlwm sai heev, uas yog qhov tseem ceeb rau kev qhib qhov ceev ceev.kev sib txuas lus quantumthiab ua kom muaj kev ua haujlwm ceev ntawm cov khoos phis tawj quantum optical. Kev siv cov txheej txheem tsim khoom uas tau tsim thiab muaj nyob hauv khw ua rau muaj kev siv thaum ntxov rau lwm qhov chaw thev naus laus zis xws li kev ntsuas thiab kev sib txuas lus. Cov khoom siv ntes no siv rau ntau yam kev siv hauv quantum optics, tuaj yeem ua haujlwm ntawm chav tsev kub, thiab tsim nyog rau kev sib txuas lus quantum, cov sensors rhiab heev xws li cov khoom siv ntes nthwv dej gravitational wave detectors, thiab hauv kev tsim cov khoos phis tawj quantum.

Txawm hais tias cov khoom siv no ceev thiab me me, lawv kuj rhiab heev. Qhov tseem ceeb rau kev ntsuas lub teeb quantum yog qhov rhiab heev rau lub suab nrov quantum. Quantum mechanics tsim cov suab nrov me me, yooj yim hauv txhua lub tshuab optical. Tus cwj pwm ntawm lub suab nrov no qhia cov ntaub ntawv hais txog hom lub teeb quantum xa mus rau hauv lub system, tuaj yeem txiav txim siab qhov rhiab heev ntawm lub sensor optical, thiab tuaj yeem siv los tsim kho dua tshiab lub xeev quantum. Kev tshawb fawb qhia tau hais tias kev ua kom lub tshuab optical me dua thiab sai dua tsis cuam tshuam nws qhov rhiab heev rau kev ntsuas lub xeev quantum. Yav tom ntej, cov kws tshawb fawb npaj yuav koom ua ke lwm yam khoom siv thev naus laus zis quantum cuam tshuam rau qhov ntsuas chip, txhim kho qhov ua tau zoo ntawm qhov tshiab.lub tshuab ntes teeb pom kev zoo, thiab sim nws hauv ntau yam kev siv sib txawv. Yuav kom ua rau lub tshuab ntes tau dav dua, pab pawg tshawb fawb tau tsim nws siv cov tshuab ua kom muaj nyob hauv khw. Txawm li cas los xij, pab pawg hais tias nws yog qhov tseem ceeb heev uas yuav tsum txuas ntxiv daws cov teeb meem ntawm kev tsim khoom loj nrog cov thev naus laus zis quantum. Yog tsis ua pov thawj tias kev tsim khoom siv quantum muaj peev xwm loj tiag tiag, qhov cuam tshuam thiab cov txiaj ntsig ntawm cov thev naus laus zis quantum yuav raug ncua thiab txwv. Qhov kev tawg ua tiav no yog ib kauj ruam tseem ceeb rau kev ua tiav cov ntawv thov loj ntawmkev siv tshuab quantum, thiab yav tom ntej ntawm kev suav lej quantum thiab kev sib txuas lus quantum yog puv nrog ntau yam tsis kawg.
