Quantum microwave Optical Technology

Quantummicrowave kuwalaluso
Microwave Optical Technologywakhala munda wamphamvu, kuphatikiza ubwino wa kuwala ndi microwave luso pokonza siginecha, kulankhulana, kumva ndi mbali zina. Komabe, machitidwe ochiritsira a microwave photonic amakumana ndi zoletsa zina, makamaka pankhani ya bandwidth ndi kukhudzika. Kuti athane ndi zovuta izi, ofufuza ayamba kufufuza ma quantum microwave photonics - gawo latsopano losangalatsa lomwe limaphatikiza malingaliro aukadaulo wa quantum ndi ma microwave photonics.

Zofunikira zaukadaulo wa quantum microwave Optical
Pakatikati paukadaulo waukadaulo wa quantum microwave Optical ndikusintha mawonekedwe achikhalidwePhotodetectormumicrowave photon linkyokhala ndi chowunikira chimodzi cha photon champhamvu kwambiri. Izi zimalola kuti dongosololi lizigwira ntchito pamagetsi otsika kwambiri, ngakhale mpaka pamlingo umodzi wa photon, komanso kuwonjezereka kwa bandwidth.
Makina amtundu wa quantum microwave photon ndi awa: 1. Mafotoni amtundu umodzi (monga ma laser attenuated 2.Electro-optic modulatorkwa ma encoding ma siginecha a microwave/RF 3. Chigawo chowongolera ma siginecha4. Zodziwira ma photon imodzi (monga Superconducting nanowire detectors) 5. Zida zamagetsi zodalira ma photon Counting (TCSPC)
Chithunzi 1 chikuwonetsa kufananitsa pakati pa maulalo amtundu wa microwave photon ndi maulalo a quantum microwave photon:

Kusiyana kwakukulu ndiko kugwiritsa ntchito ma photon detectors amodzi ndi ma module a TCSPC m'malo mwa ma photodiodes othamanga kwambiri. Izi zimathandiza kuzindikira zizindikiro zofooka kwambiri, pamene mwachiyembekezo zimakankhira bandwidth kupitirira malire a photodetectors achikhalidwe.

Single photon kuzindikira ndondomeko
Chiwembu chodziwikiratu cha photon ndi chofunikira kwambiri pamakina a quantum microwave photon. Mfundo yogwira ntchito ili motere: 1. Chizindikiro cha periodic choyambitsa chogwirizanitsa ndi chizindikiro choyezera chimatumizidwa ku gawo la TCSPC. 2. Chojambulira chimodzi cha photon chimatulutsa ma pulse angapo omwe amaimira ma photon omwe amadziwika. 3. Module ya TCSPC imayesa kusiyana kwa nthawi pakati pa chizindikiro choyambitsa ndi photon iliyonse yodziwika. 4. Pambuyo pa malupu angapo oyambitsa, histogram ya nthawi yodziwika imakhazikitsidwa. 5. Histogram ikhoza kukonzanso mawonekedwe a mawonekedwe a chizindikiro choyambirira.Masamu, zikhoza kuwonetsedwa kuti mwayi wopeza chithunzithunzi pa nthawi yoperekedwa ndi wofanana ndi mphamvu ya kuwala panthawiyo. Chifukwa chake, histogram ya nthawi yodziwikiratu imatha kuyimira molondola mawonekedwe amtundu wa chizindikiro choyezedwa.

Ubwino waukulu waukadaulo wa quantum microwave optical
Poyerekeza ndi makina owoneka bwino a ma microwave, ma quantum microwave photonics ali ndi maubwino angapo: 1. Kukhudzika kwakukulu: Imazindikira ma siginecha ofooka kwambiri mpaka pamlingo umodzi wa photon. 2. Kuwonjezeka kwa bandwidth: osati kokha ndi bandwidth ya photodetector, yokhayo yomwe imakhudzidwa ndi jitter ya nthawi ya detector imodzi ya photon. 3. Zowonjezera zotsutsana ndi kusokoneza: Kumanganso kwa TCSPC kungathe kusefa zizindikiro zomwe sizinatsekeredwe ku choyambitsa. 4. Phokoso lapansi: Pewani phokoso lomwe limabwera chifukwa cha kuzindikirika kwamtundu wamagetsi ndi kukulitsa.
