Quantum kutaurirana ndiyo yepakati chikamu che quantum ruzivo tekinoroji. Iine zvakanakira kuvanzika kwakazara, hukuru hwekutaurirana kugona, kukurumidza kutapurirana kumhanya, zvichingodaro. Inogona kupedzisa mamwe mabasa ayo ekirasi kutaurirana asingakwanisi kuita. Kukurukurirana kweQuantum kunogona kushandisa yakavanzika kiyi sisitimu, iyo isingakwanise kutsanangurwa kuti ione iyo chaiyo pfungwa yekutaurirana kwakachengeteka, saka quantum kutaurirana kwave kumberi kwesainzi uye tekinoroji munyika. Kukurukurirana kweQuantum kunoshandisa iyo quantum state sechinhu cheruzivo kuona kufambiswa kwakanaka kweruzivo. Ndiyo imwe shanduko munhoroondo yekutaurirana mushure mefoni uye kutaurirana kwemaziso.
Izvo zvakakosha zve quantum kutaurirana:
Quantum chakavanzika kiyi kugovera:
Quantum yakavanzika kiyi yekugovera haishandiswe kufambisa zvakavanzika zvemukati. Zvakadaro, ndeyekumisikidza uye kutaurirana bhuku recipher, ndiko kuti, kugovera kiyi yakavanzika kumativi ese ekutaurirana, anowanzozivikanwa se quantum cryptography kutaurirana.
Muna 1984, Bennett wekuUnited States nebrassart yeCanada vakakurudzira BB84 protocol, iyo inoshandisa quantum bits sevatakuri veruzivo kuvharidzira quantum states nekushandisa polarization maitiro echiedza kuona chizvarwa uye kugoverwa kwakachengeteka kwemakiyi akavanzika. Muna 1992, Bennett akakurudzira B92 protocol yakavakirwa pane mbiri dzisiri dzenonorthogonal quantum dziine kuyerera kuri nyore uye hafu inoshanda. Zvose izvi zvirongwa zvakavakirwa pane imwechete kana kupfuura seti ye orthogonal uye nonorthogonal single quantum states. Chekupedzisira, muna 1991, Ekert wekuUK akakurudzira E91 zvichibva pane maviri-particle maximum entanglement state, inova EPR pair.
Muna 1998, imwe nhanhatu-nyika quantum yekukurukurirana chirongwa yakakurudzirwa kusarudzwa kwepolarization pamabhesi matatu akasanganiswa anoumbwa neina polarization nyika uye kuruboshwe uye kwakaringana kutenderera muBB84 protocol. BB84 protocol yakaratidza kuve yakachengeteka yakakosha nzira yekugovera, iyo isati yatyorwa chero munhu kusvika zvino. Nheyo yehuwandu hwekusavimbika uye quantum isiri-cloning inovimbisa kuchengetedzwa kwayo kwakakwana. Naizvozvo, iyo EPR protocol ine yakakosha theoretical kukosha. Iyo inobatanidza iyo yakasungwa quantum state neyakachengetedzeka quantum kutaurirana uye inovhura nzira nyowani yekuchengetedza quantum kutaurirana.
quantum teleportation:
Dzidziso ye quantum teleportation yakakurudzirwa naBennett nemamwe masayendisiti munyika nhanhatu muna 1993 ndeye pure quantum transmission mode inoshandisa chiteshi chezvikamu zviviri zvakasungirirwa nyika kuendesa isingazivikanwe quantum state, uye budiriro ye teleportation ichasvika 100% [ 2].
Muna 199, a. Zeilinger boka reAustria rakapedza yekutanga kuyedza ongororo yemusimboti wequantum teleportation murabhoritari. Mumafirimu mazhinji, chirongwa chakadaro chinowanzoitika: chimiro chisinganzwisisike chinongoerekana chanyangarika munzvimbo imwe kamwe kamwe chinoratidzika chiri munzvimbo. Nekudaro, nekuti quantum teleportation inotyora musimboti wekuti quantum non-cloning uye Heisenberg kusagadzikana mune quantum mechanics, ingori imhando yengano yesainzi mukutaurirana kwekirasi.
Nekudaro, iyo yakasarudzika pfungwa yequantum entanglement inounzwa muhuwandu hwekutaurirana, iyo inokamura iyo isingazivikanwe quantum mamiriro eruzivo rwekutanga kuita zvikamu zviviri: ruzivo rwehuwandu uye ruzivo rwekirasi, izvo zvinoita kuti ichi chishamiso chinoshamisa chiitike. Quantum ruzivo irwo ruzivo rusina kuburitswa mukuyera maitiro, uye ruzivo rwechinyakare ndiyo chiyero chepakutanga.
Kufambira mberi muhuwandu hwekukurukurirana:
Kubva 1994, quantum kutaurirana zvishoma nezvishoma yakapinda muyedzo nhanho uye ichienderera mberi kune inoshanda chinangwa, iyo ine yakanakisa budiriro kukosha uye mabhenefiti ehupfumi. Muna 1997, pan Jianwei, musayendisiti wechidiki weChinese, uye Bow meister, sainzi wechiDutch, akaedza uye akaziva kutapurirana kure kweasingazivikanwe quantum states.
Muna Kubvumbi 2004, Sorensen et al. Yakazadzikiswa 1.45km dhata kufambisa pakati pemabhangi kekutanga nekushandisa quantum entanglement kugovera, ichimaka iyo quantum kutaurirana kubva murabhoritari kuenda padanho rekushandisa. Parizvino, tekinoroji yehuwandu hwekutaurirana yakwezva kutarisisa kwakanyanya kubva kuhurumende, indasitiri, uye dzidzo. Mamwe makambani epasi rese ane mukurumbira ari kusimudzira kushambadzira kweruzivo rwehuwandu, seBritish runhare neTelegraph Company, bhero, IBM, ku & T marabhoritari muUnited States, kambani yeToshiba kuJapan, kambani yeSiemens kuGermany, nezvimwe. 2008, European Union's "yepasi rose yakachengeteka kutaurirana network yekuvandudza chirongwa chakavakirwa pahuwandu cryptography" yakamisa 7-node yakachengeteka kutaurirana Kuratidzira uye verification network.
Muna 2010, magazini yeTime yekuUnited States yakashuma kubudirira kwekuyedza kweChina 16 km quantum teleportation muchikamu che "nhau dzinoputika" ine zita rekuti "kusvetuka kweChina Quantum Sayenzi," zvichiratidza kuti China inogona kumisa quantum communication network pakati penyika. pasi uye satellite [3]. Muna 2010, National intelligence and Communication Research Institute yeJapan neMitsubishi Electric neNEC, ID yakaverengerwa kuSwitzerland, Toshiba Europe Limited, uye Vienna yese yekuAustria yakamisa nodes nhanhatu metropolitan quantum communication network "Tokyo QKD network" muTokyo. Iyo network inotarisa pane yazvino tsvakiridzo mhedzisiro yemasangano ekutsvagisa uye makambani ane yepamusoro soro yebudiriro muhuwandu hwekutaurirana tekinoroji muJapan neEurope.
Beijing Rofea Optoelectronics Co., Ltd. iri muChina "Silicon Valley" - Beijing Zhongguancun, ibhizimusi repamusoro-soro rakatsaurirwa kushandira masangano ekutsvagisa epamba nekunze, masangano ekutsvagisa, mayunivhesiti uye bhizinesi vashandi vezvesainzi. Kambani yedu inonyanya kuita mukutsvagisa yakazvimirira uye kusimudzira, dhizaini, kugadzira, kutengesa kwezvigadzirwa zveoptoelectronic, uye inopa mhinduro nyowani uye nehunyanzvi, masevhisi emunhu evaongorori vesainzi uye mainjiniya emaindasitiri. Mushure memakore ekuzvimiririra innovation, yakagadzira akapfuma uye akakwana akatevedzana ezvigadzirwa zvemafotoelectric, ayo anoshandiswa zvakanyanya mumaspala, mauto, zvekufambisa, simba remagetsi, mari, dzidzo, zvekurapa uye mamwe maindasitiri.
Tiri kutarisira kubatana newe!
