Ukuxhumana okubethelwe nge-Quantum
Ukuxhumana okuyimfihlo kwe-quantum, okwaziwa nangokuthi ukusatshalaliswa kokhiye we-quantum, kuyindlela yokuxhumana kuphela eye yafakazelwa ukuthi iphephile ngokuphelele ezingeni lamanje lokuqonda komuntu. Umsebenzi wayo ukusabalalisa ngokuguquguqukayo ukhiye phakathi kuka-Alice noBob ngesikhathi sangempela ukuqinisekisa ukuphepha okuphelele kokuxhumana.
Ukuxhumana okuphephile kwendabuko ukukhetha kusengaphambili nokunikeza ukhiye lapho u-Alice noBob behlangana, noma ukuthumela umuntu okhethekile ukuzoletha ukhiye. Le ndlela ayisebenzi kahle futhi iyabiza, futhi ivame ukusetshenziswa ezimweni ezikhethekile njengokuxhumana phakathi komkhumbi-ngwenya kanye nesisekelo. Ukusatshalaliswa kokhiye we-Quantum kungasungula isiteshi se-quantum phakathi kuka-Alice noBob, futhi kunikeze okhiye ngesikhathi sangempela ngokwezidingo. Uma kwenzeka ukuhlaselwa noma ukulalelwa kwemfihlo ngesikhathi sokusabalalisa okhiye, bobabili u-Alice noBob bangabathola.
Ukusatshalaliswa kokhiye we-quantum kanye nokutholwa kwe-photon eyodwa kuyizinto zobuchwepheshe ezibalulekile zokuxhumana okuphephile kwe-quantum. Eminyakeni yamuva nje, amanyuvesi amakhulu kanye nezikhungo zocwaningo zenze inani elikhulu lezifundo zokuhlola kubuchwepheshe obubalulekile zokuxhumana kwe-quantum.Ama-modulators e-Electro-opticfuthiama-laser obubanzi bomugqa omncaneIthuthukiswe ngokuzimela yinkampani yethu isetshenziswe kabanzi ezinhlelweni zokusabalalisa izihluthulelo ze-quantum. Thatha ukusatshalaliswa kwezihluthulelo ze-quantum eziguquguqukayo okuqhubekayo njengesibonelo, njengoba kuboniswe esithombeni esilandelayo.
Ngokwezimiso ezingenhla, i-electro-optical modulator (AM, PM) iyingxenye ebalulekile yesistimu yokuhlola ukusabalalisa ukhiye we-quantum, enekhono lokuguqula ubukhulu noma isigaba sensimu ye-optical, ukuze isignali yokufaka idluliselwe nge-optical quantum. Uhlelo ludinga ukuthi i-light intensity modulator ibe ne-high extinction ratio kanye nokulahlekelwa okuphansi kokufakwa ukuze ikhiqize isignali yokukhanya evunguzayo ye-high extinction ratio.
