Kugwiritsa ntchito ukadaulo wa quantum microwave photonics

Kugwiritsa ntchito kwa quantumteknoloji ya microwave photonics

Kuzindikira kofooka kwa chizindikiro
Chimodzi mwazinthu zodalirika kwambiri zaukadaulo wa quantum microwave photonics ndikuzindikira ma siginecha ofooka kwambiri a microwave/RF. Pogwiritsa ntchito kujambula kwa photon imodzi, machitidwewa ndi ovuta kwambiri kuposa njira zamakono. Mwachitsanzo, ochita kafukufuku awonetsa quantum microwave photonic system yomwe imatha kuzindikira zizindikiro zotsika -112.8 dBm popanda kukulitsa kwamagetsi. Kukhudzika kwakukulu kumeneku kumapangitsa kukhala koyenera kwa mapulogalamu monga kulumikizana kwakuya kwamlengalenga.

Zithunzi za Microwavekukonza chizindikiro
Quantum microwave photonics imagwiritsanso ntchito ma siginecha apamwamba a bandwidth monga kusuntha ndi kusefa. Pogwiritsa ntchito mawonekedwe owoneka bwino komanso kusintha kutalika kwa kuwala, ofufuzawo adawonetsa kuti gawo la RF limasinthira mpaka 8 GHz RF kusefa ma bandwidth mpaka 8 GHz. Chofunika kwambiri, zonsezi zimatheka pogwiritsa ntchito magetsi a 3 GHz, zomwe zimasonyeza kuti ntchitoyo imadutsa malire achikhalidwe.

Kusawerengeka kwanthawi kochepa kwanthawi
Kuthekera kumodzi kosangalatsa komwe kumabwera chifukwa cha kuchuluka kwachulukidwe ndikujambula mafupipafupi omwe si amderalo mpaka nthawi. Njirayi imatha kupanga mapu amtundu wa gwero lachithunzi chimodzi lomwe limapopedwa mosalekeza kupita kumalo akutali komwe kuli kutali. Dongosololi limagwiritsa ntchito ma photon awiriawiri omangika momwe mtengo umodzi umadutsa pasefa yowoneka bwino ndipo inayo imadutsa pagawo lobalalitsa. Chifukwa cha kudalira kwafupipafupi kwa ma photon otsekeredwa, mawonekedwe osefera amawonekedwe osakhala apafupi ndi nthawi.
Chithunzi 1 chikuwonetsa lingaliro ili:

Njirayi imatha kukwaniritsa kuyeza kowoneka bwino popanda kuwongolera mwachindunji gwero la kuwala.

Kumverera kopanikizika
Quantummicrowave kuwalaukadaulo umaperekanso njira yatsopano yolumikizira ma siginecha a Broadband. Pogwiritsa ntchito kusakhazikika komwe kumapezeka pakuzindikira kuchuluka, ofufuza awonetsa kachitidwe ka quantum compressed sensor system yomwe imatha kuchira.10 GHz RFmawonekedwe. Dongosololi limasinthira siginecha ya RF ku chikhalidwe cha polarization cha photon yogwirizana. Kuzindikira kwa chithunzi chimodzi kumapereka matrix oyezera mwachisawawa kuti mumve mopanikizika. Mwanjira iyi, chizindikiro cha Broadband chikhoza kubwezeretsedwanso pamlingo wa Yarnyquist sampling.

Kugawa makiyi a Quantum
Kuphatikiza pa kupititsa patsogolo ntchito zachikhalidwe za microwave photonic, ukadaulo wa quantum ukhozanso kupititsa patsogolo njira zoyankhulirana zochulukira monga quantum key distribution (QKD). Ofufuzawa adawonetsa subcarrier multiplex quantum key distribution (SCM-QKD) pochulukitsa ma microwave photons subcarrier pa quantum key distribution (QKD) system. Izi zimalola makiyi angapo odziyimira pawokha kuti azitha kufalikira pamtunda umodzi wokha wa kuwala, potero kumakulitsa luso la mawonekedwe.
Chithunzi 2 chikuwonetsa lingaliro ndi zotsatira zoyeserera za machitidwe awiri a SCM-QKD:

Ngakhale ukadaulo wa quantum microwave photonics ukulonjeza, pali zovuta zina:
1. Zochepa zenizeni zenizeni: Dongosolo lamakono limafuna nthawi yochuluka yosonkhanitsa kuti amangenso chizindikiro.
2. Kuvuta kuthana ndi zizindikiro zowonongeka / kumodzi: Chiwerengero cha kumangidwanso chimachepetsa kugwiritsidwa ntchito kwa zizindikiro zosabwerezabwereza.
3. Sinthani kukhala mawonekedwe enieni a microwave: Njira zowonjezera zimafunikira kuti musinthe histogram yomangidwanso kukhala mawonekedwe ogwiritsiridwa ntchito.
4. Mawonekedwe a chipangizo: Kuphunziranso mozama za machitidwe a zida za quantum ndi ma microwave photonic mumakina ophatikizika ndikofunikira.
5. Kuphatikiza: Machitidwe ambiri masiku ano amagwiritsa ntchito zigawo zazikulu za discrete.

Kuti athetse mavutowa ndikupititsa patsogolo gawoli, njira zingapo zowunikira zikutuluka:
1. Pangani njira zatsopano zowonetsera nthawi yeniyeni ndi kuzindikira kamodzi.
2. Onani mapulogalamu atsopano omwe amagwiritsa ntchito tcheru kwambiri, monga kuyeza kwa microsphere.
3. Tsatirani kukwaniritsidwa kwa ma photon ophatikizika ndi ma electron kuti muchepetse kukula ndi zovuta.
4. Phunzirani kuyanjana kwamphamvu kwa zinthu zowunikira mumayendedwe ophatikizika a quantum microwave photonic.
5. Phatikizani ukadaulo wa quantum microwave photon ndi matekinoloje ena omwe akubwera.
