Ubuchwepheshe bolwazi lwe-Quantum buyibuchwepheshe obusha bolwazi ubuchwepheshe obususelwa kuma-quantum mechanics, amakhodi, amakhaza futhi adlulisele imininingwane engokomzimba equkethweuhlelo lwe-quantum. Ukuthuthukiswa kanye nokusetshenziswa kobuchwepheshe bolwazi lwe-quantum kuzosilethela ku "Quantum Age", futhi kufezeke ukusebenza kahle komsebenzi, izindlela zokuxhumana ezivikelekile nendlela yokuphila elula futhi eluhlaza.
Ukusebenza kahle kokuxhumana phakathi kwezinhlelo ze-quantum kuncike emandleni abo okusebenzisana nokukhanya. Kodwa-ke, kunzima kakhulu ukuthola impahla engasebenzisa ngokugcwele izakhiwo ze-quantum ze-optical.
Muva nje, ithimba lokucwaninga elisesikhungweni samakhemikhali eParis naseKarlsruhe Institute of Technology ndawonye ikhombisa amandla e-crystal yamangqamuzana asuselwa kuma-rare Earth Europuum Ions (EU³ +) ukuthola izinhlelo ezinhlelweni ze-quantum ze-optical. Bathole ukuthi ukukhishwa kwe-linewidth kwe-lintra-nsundu yale e-EU³ + i-molecular crystal inika amandla ukusebenzisana okusebenzayo ngokukhanya futhi kunenani elibalulekile ngaphakathiUkuxhumana kwe-Quantumkanye ne-quantum computing.
Umdwebo 1: Ukuxhumana kwe-Quantum kususelwa ku-Rare Earth Europrouum ama-crystals
I-Quantum States ingaba ngcono, ngakho-ke ulwazi lwe-quantum lungahle lube khona. I-quet eyodwa ingamelela ngasikhathi sinye izizwe ezahlukahlukene ezihlukene phakathi kuka-0 no-1, okuvumela idatha ukuthi icutshungulwe ngokufana kuma-batches. Ngenxa yalokho, amandla okukhokhisa amakhompyutha we-quantum azokhulisa ngokuqhathaniswa namakhompyutha endabuko wendabuko. Kodwa-ke, ukuze wenze imisebenzi ye-computational, i-suppoposition of qubits kumele ikwazi ukuphikelela ngokuqinile isikhathi esithile. Kumakhenikhi we-quantum, lesi sikhathi sokuqina saziwa ngokuthi isikhathi sokuhlangana. Ama-spins enuzi ama-molekyuli ayinkimbinkimbi angafinyelela ama-superposition asho ngezikhathi zokuphila ezomile zomile ngoba ithonya lemvelo ezinhlolweni zenuzi livikelwe ngempumelelo.
Ama-Ion angu-Rare Eon kanye namakristalu ama-moleculal kuyizinhlelo ezimbili ezisetshenzisiwe kubuchwepheshe be-quantum. I-Rare Ears ion inezakhiwo ezinhle kakhulu ze-Optical and Spin, kepha zinzima ukuhlanganiswa kuyoAmadivayisi we-Optical. Amakristalu ama-Molecular kulula ukuhlanganisa, kepha kunzima ukusungula ukuxhumana okuthembekile phakathi kwe-spin nokukhanya ngoba amabhendi wokuphuma abanzi kakhulu.
Amakristalu omhlaba aqabulayo asungulwe kulo msebenzi ahlanganisa kahle izinzuzo zazo zombili kulokho, ngaphansi kokuxoshwa kwe-laser, eu³ + angakhipha izithombe ziphethe imininingwane nge-nuclear spin. Ngokuhlola okuthile kwe-laser, interface ebonakalayo ye-Optical / Nuclear Spin ingenziwa. Ngalesi sisekelo, abacwaningi baphinde bathola ukubhekana nezinga le-Nuclear Spin Level, ukugcinwa kwama-photons, kanye nokwenza umsebenzi wokuqala we-quantum.
Ukuze uthole i-computing esebenza kahle ye-quantum, i-qubits eminingi ebambekile imvamisa iyadingeka. Abaphenyi babonise ukuthi amakristalu e-EU³ + kulezi zinhlaka ezingenhla ama-moleculals angakwazi ukufezekisa ukuhlanganiswa kwe-quantum ngokuhlangana kwegesi kagesi elahlekile, ngaleyo ndlela kuvumele ukucubungula ulwazi lwe-quantum. Ngoba amakristalu ama-molefanelar aqukethe izindawo eziningi zomhlaba ezingandile, izinqumo eziphakeme ze-quet ahlukahlukene zingatholakala.
Enye imfuneko ye-computing ye-quantum ukuphendula kwe-qubits yomuntu ngamunye. Indlela yokulungisa ekwakheni kulo msebenzi ingathuthukisa ijubane lokufunda futhi ivikele ukuphazanyiswa kwesiginali yesekethe. Uma kuqhathaniswa nezifundo ezedlule, ukuhlangana kwamakristalu e-EU³ + ama-moleculals abikiwe kulo msebenzi kuthuthukiswa cishe ngenkulungwane, ukuze iziqubu ze-nuclear spin zingakhokhwa ngendlela ethile.
Amasiginali we-Optical nawo alungele ukusatshalaliswa kolwazi lwe-quatum olude ukuxhuma amakhompyutha we-quantum ukuze kukhulunywe ngokukude kwe-quantum. Ukucatshangelwa okwengeziwe kunganikezwa ekuhlanganiseni amakristalu amasha + ama-molecular ama-crystals esithombeni se-photoc ukuthuthukisa isinali elikhanyayo. Lo msebenzi usebenzisa ama-molekyuli omhlaba angavamile njengesisekelo se-Quantum Internet, futhi kuthatha isinyathelo esibalulekile kwi-Metual Quantum Communication Archites.
