Horumarinta tignoolajiyada isgaarsiinta quantum ee Shiinaha waxay soo martay heerar kala duwan. Laga bilaabo wejigii daraasadda iyo cilmi-baarista ee 1995, sannadkii 2000, Shiinuhu wuxuu dhammaystiray tijaabada qaybinta quantum-ka oo dhan 1.1 km. Muddadii u dhaxaysay 2001 ilaa 2005 waxay ahayd weji horumar degdeg ah oo lagu guulaystay tijaabooyin qaybinta furaha quantum ee masaafo dhan 50 km iyo 125 km [1].
Sanadihii la soo dhaafay, Shiinuhu wuxuu horumarro la taaban karo ka sameeyay isgaarsiinta tirada. Shiinuhu waxa uu ahaa kii ugu horeeyey ee hawada u dira dayax-gacmeed tijaabo ah oo saynis ah, “Micius”, waxa aanu dhisay khad isgaarsiineed sugan oo sugan oo kummanaan kiiloomitir ah inta u dhaxaysa Beijing iyo Shanghai. Shiinuhu waxa uu si guul leh u dhisay shabakad isgaadhsiineed oo isku xidhan oo ka bilaabmaysa dhulka ilaa hawada sare oo dhererkeedu dhan yahay 4600 kilomitir. Taas waxa dheer, Shiinuhu waxa kale oo uu horumar la taaban karo ka gaadhay xisaabinta tirada. Tusaale ahaan, Shiinuhu waxa uu soo saaray noocii ugu horreeyay adduunka ee kumbiyuutarka quantum-ka, waxa uu si guul leh u dhisay prototype quantum computing “Jiuzhang” oo wata 76 photon, waxa uu si guul leh u dhisay prototype-ka superconducting quantum computing “Zu Chongzhi” oo ka kooban 62 qubits.
Isticmaalka qayb dadban ee hababka isgaarsiinta quantum waa muhiimada ugu weyn. Tusaale ahaan, aaladaha ay ka midka yihiin attenuators microwave-ka, lamaanayaasha jihaynta, qaybiyayaal koronto, filtarrada mikrowave, wejiga wareejinta, iyo go'doominta mikrowave ayaa laga yaabaa in la isticmaalo. Aaladahan waxaa ugu horrayn loo shaqeeyaa si ay u farsameeyaan oo ay u xakameeyaan calaamadaha microwave-ka ee ay dhaliso quantum bits.
Attenuators Microwave waxay yareyn kartaa awoodda calaamadaha microwave-ka si looga hortago faragelinta qaybaha kale ee nidaamka sababtoo ah xoogga signalada xad-dhaafka ah. Lammaanayaasha jihooyinku waxay u kala qaybin karaan calaamadaha microwave-ka laba qaybood, iyagoo fududaynaya habaynta calaamadaha kakan. Shaandhooyinka Microwave-ku waxay shaandheyn karaan calaamadaha soo noqnoqoshada gaarka ah ee falanqaynta calaamadaha iyo habaynta. Wareejinta marxaladaha waxay bedeli karaan wajiga calaamadaha microwave-ka, ee loo isticmaalo in lagu xakameeyo xaaladda quantum bits. Go'doominta mikrowave-ku waxay hubin karaan in calaamadaha microwave-ku ay ku faafaan hal jiho oo keliya, ka hortagga calaamadaha dib-u-socodka iyo faragelinta nidaamka.
Si kastaba ha ahaatee, kuwani waa qayb ka mid ah qaybaha microwave-ka ee dadban ee laga yaabo in loo isticmaalo isgaadhsiinta tirada. Qaybaha gaarka ah ee la adeegsan doono waxay u baahan doonaan in la go'aamiyo iyadoo lagu salaynayo naqshadaynta iyo shuruudaha nidaamka isgaarsiinta tirada gaarka ah.
Fikradda ayaa bixisa qaybo badan oo ka mid ah mikrowave dadban ee isgaarsiinta quantum
