Puisano e patiloeng ea Quantum

Puisano ea lekunutu ea Quantum, eo hape e tsejoang e le quantum key distribution, ke eona feela mokhoa oa puisano o pakiloeng o bolokehile ka botlalo maemong a hajoale a kelello ea motho. Mosebetsi oa eona ke ho fana ka senotlolo lipakeng tsa Alice le Bob ka nako ea nnete ho netefatsa polokeho e felletseng ea puisano.

Puisano e sireletsehileng ea setso ke ho khetha esale pele le ho abela senotlolo ha Alice le Bob ba kopana, kapa ho romela motho ea khethehileng ho tlisa senotlolo. Mokhoa ona ha o bonolo ebile o theko e boima, 'me hangata o sebelisoa maemong a khethehileng a kang puisano pakeng tsa sekepe sa metsing le setsi. Kabo ea senotlolo sa Quantum e ka theha mocha oa quantum lipakeng tsa Alice le Bob, 'me ea abela linotlolo ka nako ea nnete ho latela litlhoko. Haeba litlhaselo kapa ho mamela li etsahala nakong ea kabo ea linotlolo, Alice le Bob ba ka li lemoha.

Kabo ea senotlolo sa Quantum le ho lemoha ha photon e le 'ngoe ke mahlale a bohlokoa a puisano e sireletsehileng ea quantum. Lilemong tsa morao tjena, liunivesithi tse kholo le litsi tsa lipatlisiso li entse palo e kholo ea lithuto tsa liteko mabapi le mahlale a bohlokoa a puisano ea quantum.Li-modulators tsa elektro-opticleli-lasers tsa bophara ba mola o moqotetsanee ikemetseng e ntlafalitsoeng ke k'hamphani ea rona e sebelisitsoe haholo lits'ebetsong tsa kabo ea bohlokoa ea quantum. Nka kabo ea bohlokoa e tsoelang pele ea quantum joalo ka mohlala, joalo ka ha ho bonts'itsoe setšoantšong se latelang.

Ho ea ka melao-motheo e ka holimo, electro-optical modulator (AM, PM) ke karolo ea bohlokoa ea quantum key distribution test system, e nang le bokhoni ba ho fetola amplitude kapa karolo ea sebaka sa optical, e le hore pontšo ea ho kenya e ka ba teng. e fetisoa ka optical quantum. Sistimi e hloka hore modulator ea matla a khanya e be le tekanyo e phahameng ea ho timela le tahlehelo e tlase ea ho kenya e le ho hlahisa sekhahla se phahameng sa ho timela ha lets'oao la leseli la pulsed.

Lihlahisoa tse amanang Mohlala le tlhaloso
Laser ea bophara ba mola o moqotetsane ROF-NLS letoto la laser, RIO fiber laser, NKT fiber laser
mohloli oa leseli la ns pulse (laser) ROF-PLS series pulse light source, ka hare le ka ntle trigger ea boikhethelo, bophara ba pulse le ho pheta-pheta khafetsa ho ka fetoloa.
Modulator ea matla ROF-AM letoto la li-modulator, ho fihla ho 20GHz bandwidth, tekanyo e phahameng ea ho timela ho fihla ho 40dB
Modulator ea mohato ROF-PM letoto la modulator, bandwidth e tloaelehileng ea 12GHz, halofo ea maqhubu a motlakase ho ea ho 2.5V
Microwave amplifier ROF-RF letoto la li-analogue amplifier, tšehetso ea 10G, 20G, 40G microwave amplification, bakeng sa koloi ea electro-optical modulator.
Photodetector e leka-lekaneng Letoto la ROF-BPR, tekanyo e phahameng ea ho hana mokhoa o tloaelehileng, lerata le tlase
