Toshiba (enye yezinto ezinzima kwihlabathi lobuchwepheshe) ibhengeze kule veki ukuba igqithise ngempumelelo ulwazi lobungakanani kwi-fiber optics I-600 km ubude.
Abaphandi beenkampani setha irekhodi elitsha lomgama kwaye uxele ikamva elitsha lenethiwekhi ezinkulu ze-quantum Banokuthumela ulwazi ngokukhuselekileyo phakathi kwezixeko kunye namazwe. Ezi nzulu-lwazi zibonise ukuba zinokuhambisa izixa ze-quantum ngaphezulu kwamakhulu eekhilomitha zefayibha ebonakalayo ngaphandle kokufaka ikhowudi kwidatha e-ethe-ethe ekhompyutheni.
Ngokwabo, Isizathu sempumelelo yayo kungenxa yetekhnoloji entsha ezinzisa ukuguquguquka kwemo engqongileyo ezenzeka kwifayibha. Oku kufumanisa kungahamba indlela ende ekwenzeni i-intanethi yesizukulwana esilandelayo, apho izazinzulu zinethemba lokuba ngenye imini ziya kuhamba imigama yehlabathi.
Ukujongana neemeko ezingazinzanga ngaphakathi kweentsinga zamehlo, abaphandi baseToshiba Baqulunqe indlela entsha ebizwa ngokuba 'kukuzinza kwebhendi ezimbini'. Inkqubo entsha ithumela imiqondiso emibini yokubonisa kwimilinganiselo eyahlukeneyo, ukunciphisa i-jitter kwimicu emide.
Ubude bokuqala busetyenziselwa ukucima ukutshintsha okukhawulezayo, ngelixa elesibini, elinobude obulinganayo obufana ne-optical qubits, ivumela uhlengahlengiso lwesigaba.
Abaphandi ifumanise ukuba kunokwenzeka ukugcina isigaba se-optical ye-quantum signal rhoqo kwiqhekeza lobude, Ngokuchaneka kwamashumi amabini eeanometer, nasemva kokusasazeka kumakhulu eekhilomitha yefayibha. Ukuba oku kungaguquguquki akuhlawulwanga ngexesha lokwenyani, ifayibha iyanda kwaye ineekhontrakthi ngokomahluko wobushushu, ofaka ulwazi lobungakanani.
Omnye kwezicelo zokuqala zale ndlela kwilizwe lokwenyani iya kuba kukuhanjiswa kwezitshixo ze-quantum (QKD) kwimigama emide. Ngokwengxelo epapashwe nguToshiba kwiveki ephelileyo, iinkqubo ze-QKD zorhwebo ngoku zikhawulelwe kwi-100-200 km ye-fiber optics. Iqela lophando lenkampani sele lisebenzise itekhnoloji yokuvavanya i-QKD kumgama omde.
Inkqubo Ixhomekeke kumanethiwekhi amaninzi ukudala izitshixo ezikhuselekileyo ezingenakunqandwa, Oko kuthetha ukuba abasebenzisi banokutshintshiselana ngokukhuselekileyo ngolwazi oluyimfihlo, olufana neengxelo zebhanki okanye iingxelo zonyango, ngejelo lonxibelelwano elingathembekanga, njenge-Intanethi.
“Kwiminyaka yakutshanje, iQKD ibisetyenziselwa ukukhusela uthungelwano lweMetro. Le nkqubela phambili yamva nje yandisa ukufikelela kwelona khonkco liphezulu, ukwenzela ukuba izixeko zinokudityaniswa kumazwe nakwilizwekazi, ngaphandle kokusebenzisa iindawo ezinokuthenjwa eziphakathi. Ukufezekiswa kweQKD kusetyenziswa isathelayithi, izakusivumela ukuba sakhe uthungelwano olunqabisekileyo lomhlaba jikelele, "utshilo u-Andrew Shields, uMlawuli weeQuantum Technologies eToshiba Europe.
Ngexesha lonxibelelwano, i I-QKD isebenza ngokwenza elinye lamaqela amabini libethele idatha ngokufaka iikhowudi iqhosha lokufihla kwii-qubit kwaye uthumele ezi qubit kwelinye iqela ngomnatha wobungakanani. Nangona kunjalo, ngenxa yemithetho ye-quantum mechanics, akunakwenzeka ukuba i-spy ibambe i-qubits ngaphandle kokushiya i-evesdrop ebonakalayo kubasebenzisi, abanokuthi emva koko bathathe amanyathelo okukhusela ulwazi, ngokweqela leToshiba.
Ngokungafaniyo nokubhala i-classical, i-QKD ayixhomekekanga kubunzima bemathematika kwisisombululo sezokhuseleko, kodwa isekwe kwimithetho ye-physics. Oku kuthetha ukuba neekhompyuter ezinamandla azinakho ukuqhekeza izitshixo ezisekwe qubit. Ke kulula ukubona ukuba kutheni umbono utsalela umdla wabadlala kuwo onke amabakala obomi, ukusuka kumaziko emali ukuya kwiiarhente zobuntlola.
Uphando lukaToshiba luxhaswe inxenye yi-European Union, Ukubonisa umdla omkhulu kuphuhliso lonxibelelwano lobungakanani. Kwangelo xesha, isicwangciso seminyaka emihlanu sase China sikwabeka ugxininiso olukhethekileyo kuthungelwano lwe-quantum, ngelixa i-United States kutshanje ipapashe isicwangciso sobuchule esibonisa isikhokelo sinyathelo nenyathelo sokuseka i-Intanethi ye-Intanethi.
I-intanethi ye-intanethi kulindeleke ukuba isebenzise izinto ezingenakwenzeka ngezicelo zewebhu zanamhlanje Kwaye oku kuphuma kwisizukulwana sonxibelelwano oluphantse lube bubungqina ekudalweni kwamaqela ezixhobo zonxibelelwano ezidityanisiweyo, ngokudibeneyo, ezinokugqitha amandla ekhompyuter yezixhobo eziqhelekileyo.

Kuya kufuneka ulahlekise kakhulu ukungqina into enjalo. Akukho, kwaye ayisoze ibekho, akukho nto ingenakungenwa, akukho nto inokuphinda isuswe, kodwa ukuba umntu unomdla wokwenene, baya kuyikhahlela ngo-0.5.
