Ngomhla we-20 kaJulayi, uDkt James Quach, ingcali kwi-quantum physics, wajoyina iYunivesithi yaseAdelaide e-Australia njengomfundi otyeleleyo ukukhuthaza ukusetyenziswa okusebenzayo kweebhetri ze-quantum.

UGqr Quark uphumelele kwiYunivesithi yaseMelbourne kwaye wasebenza njengomphandi kwiYunivesithi yaseTokyo kunye neYunivesithi yaseMelbourne ngokulandelelana. Ibhetri yequantum yibhetri ephezulu ngokwethiyori ekwaziyo ukutshaja ngoko nangoko. Le ngcamango yacetywa okokuqala ngo-2013.

Uphononongo lubonise ukuba, kwinkqubo yokutshaja, xa kuthelekiswa ne-quantum engabanjwanga, i-quantum edibeneyo ihamba umgama omfutshane phakathi kwe-low-energy state kunye ne-high-energy state. I-qubits ngakumbi, i-entanglement yomelele, kwaye ngokukhawuleza inkqubo yokutshaja iya kuba ngenxa “ye-quantum acceleration” eyenzekayo. Ukucinga ukuba i-1 qubit ithatha iyure ye-1 ukuhlawula, i-6 qubits idinga kuphela imizuzu ye-10.

“Ukuba kukho i-10,000 qubits, inokuhlawuliswa ngokupheleleyo ngaphantsi kwesibini,” kusho uDkt Quark.

I-Quantum physics ifunda imithetho yentshukumo kwinqanaba leathomu kunye nemolekyuli, ngoko ke i-physics eqhelekileyo ayinakucacisa imithetho yentshukumo yesuntswana kwinqanaba le-quantum. Ibhetri ye-quantum, evakala ngathi “engaqhelekanga”, ixhomekeke “kwi-entanglement” ekhethekileyo ye-quantum ekufuneka ifezekiswe.

I-Quantum entanglement ibhekisela kwinto yokuba emva kokuba iinqununu ezininzi zisetyenzisiwe omnye komnye, ekubeni iimpawu zengqungquthela nganye ziye zadibaniswa kwindalo yonke, akunakwenzeka ukuchaza uhlobo lwesicatshulwa ngasinye, kuphela uhlobo lwenkqubo yonke.

“Kungenxa yokuba (quantum) entanglement ukuba kunokwenzeka ukukhawulezisa inkqubo yokutshaja ibhetri.” UGqr Quark uthe.

Nangona kunjalo, kusekho iingxaki ezimbini ezaziwayo ezingasonjululwanga ekusebenziseni okusebenzayo kweebhetri ze-quantum: i-quantum decoherence kunye nokugcinwa kwamandla aphantsi.

I-Quantum entanglement ineemfuno eziphezulu kakhulu kokusingqongileyo, oko kukuthi, ubushushu obuphantsi kunye neenkqubo ezizimeleyo. Inkqubo ye-quantum eqhelekileyo ayiyona inkqubo yodwa, kwaye akunakwenzeka ukugcina isimo se-quantum ixesha elide. Ngethuba nje le miqathango iguquka, i-quantum kunye nendalo yangaphandle iya kusetyenziswa kwaye ukuhambelana kwe-quantum kuya kuncitshiswa, oko kukuthi, “i-decoherence” effect, kunye ne-quantum entanglement iya kunyamalala.

Ngokuphathelele ukugcinwa kwamandla kwiibhetri ze-quantum, isazi sefilosofi sase-Italiya uJohn Gould sathi ngo-2015: “Ukugcinwa kwamandla kwiinkqubo ze-quantum zininzi ii-odolo zobukhulu ezincinci kunezo zezixhobo zombane zemihla ngemihla. Sisanda kuqinisekisa ngokwethiyori ukuba ifaka inkqubo. Xa kuziwa kumandla, i-quantum physics inokuzisa isantya. ”

Nokuba kusekho iingxaki ekufuneka zisonjululwe, uGqr Quark useqinisekile ngokusetyenziswa okusebenzayo kweebhetri ze-quantum. Uthe: “Uninzi lweengcali zefiziksi kufuneka zicinge njengam, zicinga ukuba iibhetri zequantum zibuchwephesha besicelo esingenakuzifumana ngokutsiba nje kube kanye.”

Injongo yokuqala kaGqr. Quark kukwandisa ithiyori yeebhetri ze-quantum, ukwakha imeko-bume evumela ukuba i-quantum entanglement kwibhubhoratri, kunye nokudala ibhetri yokuqala ye-quantum.

Nje ukuba zikhuthazwe ngempumelelo ukuba zisetyenziswe ngokubonakalayo, iibhetri zequantum ziya kuthatha indawo yeebhetri eziqhelekileyo ezisetyenziswa kwizixhobo ezincinci zombane ezifana neeselfowuni. Ukuba ibhetri yequantum enomthamo omkhulu owaneleyo inokuveliswa, inokusebenzisa izixhobo ezinkulu ezinikwa amandla ahlaziyekayo njengezithuthi zamandla amatsha.
