Quantum encrypted kutaurirana
Quantum yakavanzika kutaurirana, inozivikanwawo se quantum kiyi yekugovera, ndiyo yega nzira yekutaura yakaratidzirwa kuve yakachengeteka chose padanho rekuziva remunhu. Basa rayo ndere kugovera zvine simba kiyi pakati paAlice naBob munguva chaiyo kuti ive nechokwadi chekuchengetedzwa kwakakwana kwekutaurirana.
Kutaurirana kwakachengeteka kwechinyakare ndekwekufanosarudza uye kupa kiyi kana Alice naBob vasangana, kana kutumira munhu akakosha kuti aendese kiyi. Iyi nzira haina kunaka uye inodhura, uye inowanzoshandiswa mumamiriro ezvinhu anokosha akadai sekukurukurirana pakati pe submarine ne base. Quantum kiyi yekugovera inogona kumisikidza quantum chiteshi pakati paAlice naBob, uye kupa makiyi munguva chaiyo zvinoenderana nezvinodiwa. Kana kurwiswa kana kuterera kukaitika panguva yekugovera kiyi, Alice naBob vanogona kuzviona.
Quantum kiyi yekugovera uye imwe chete yekuona photon ndiwo akakosha matekinoroji ehuwandu hwakachengeteka kutaurirana. Mumakore achangopfuura, mayunivhesiti makuru uye masangano ekutsvagisa akaita nhamba huru yezvidzidzo zvekuyedza pane akakosha matekinoroji ehuwandu hwekutaurirana.Electro-optic modulatorsuyenhete linewidth lasersyakazvimiririra yakagadziridzwa nekambani yedu yakashandiswa zvakanyanya muquantum kiyi yekugovera masisitimu. Tora inoenderera inoshanduka quantum kiyi yekugovera semuenzaniso, sezvakaratidzwa mumufananidzo unotevera.
Zvinoenderana nemisimboti iri pamusoro, iyo electro-optical modulator (AM, PM) chikamu chakakosha cheiyo quantum kiyi yekugovera bvunzo sisitimu, iyo inokwanisa kugadzirisa amplitude kana nhanho yenzvimbo yemaziso, kuitira kuti chiratidzo chekuisa chigone kuve. inoparidzirwa kuburikidza ne optical quantum. Iyo sisitimu inoda iyo light intensity modulator kuti ive nereshiyo yekutsakatika kwepamusoro uye kurasikirwa kwekuisa pasi kuitira kuti ibudise yakakura yekudzima reshiyo pulsed chiedza chiratidzo.
| Zvigadzirwa zvinoenderana | Muenzaniso uye tsananguro |
| Narrow linewidth laser | ROF-NLS yakatevedzana laser, RIO faibha laser, NKT faibha laser |
| ns pulse light source (laser) | ROF-PLS yakatevedzana pulse light source, yemukati nekunze inokonzeresa sarudzo, pulse hupamhi uye yekudzokorora frequency inogadziriswa. |
| Kusimba modulator | ROF-AM akatevedzana modulators, anosvika 20GHz bandwidth, yakakwira yekudzima chiyero kusvika ku40dB |
| Phase modulator | ROF-PM yakatevedzana modulator, yakajairika bandwidth 12GHz, hafu wave voltage kudzika kusvika 2.5V |
| Microwave amplifier | ROF-RF yakatevedzana analog amplifier, inotsigira 10G, 20G, 40G microwave chiratidzo chekusimudzira, ye electro-optical modulator drive. |
| Balanced Photodetector | ROF-BPR yakatevedzana, yakakwira yakajairika-modhi yekuramba ratio, yakaderera ruzha |
