Ngomhla zingama-20 kuJulayi, uDkt James Quach, uchwepheshe we-quantum physics, wajoyina iNyuvesi yase-Adelaide e-Australia njengesazi esivakashile ukuze akhuthaze ukusetshenziswa okungokoqobo kwamabhethri e-quantum.

UDkt. Quark uthweswe iziqu eNyuvesi yaseMelbourne futhi wasebenza njengomcwaningi eNyuvesi yaseTokyo naseNyuvesi yaseMelbourne ngokulandelana. Ibhethri ye-Quantum ibhethri elikhulu ngokomcabango elinamandla okushaja ngaso leso sikhathi. Lo mqondo wahlongozwa okokuqala ngo-2013.

Ucwaningo luye lwabonisa ukuthi, enqubweni yokushaja, uma kuqhathaniswa ne-quantum engabanjwanga, i-quantum eboshiwe ihamba ibanga elifushane phakathi kombuso wamandla aphansi kanye nesimo samandla aphezulu. Ama-qubits amaningi, kuqina ukubopha, futhi ngokushesha inqubo yokushaja izoba ngenxa “yokusheshisa kwe-quantum” okwenzekayo. Uma sicabanga ukuthi i-qubit engu-1 ithatha ihora elingu-1 ukushaja, ama-qubits angu-6 adinga imizuzu eyi-10 kuphela.

“Uma kukhona ama-qubits angu-10,000, angashajwa ngokugcwele ngaphansi kwesekhondi,” kusho uDkt. Quark.

I-Quantum physics ifunda imithetho yokunyakaza ezingeni le-athomu nelamangqamuzana, ngakho-ke i-physics evamile ayikwazi ukuchaza imithetho yokunyakaza kwezinhlayiyana ezingeni le-quantum. Ibhethri ye-quantum, ezwakala “engavamile”, incike “ekungeneni” okukhethekile kwe-quantum okumele kufezeke.

I-Quantum entanglement ibhekisela eqinisweni lokuthi ngemva kokuba izinhlayiya eziningana zisetshenziselwa omunye nomunye, njengoba izici zezinhlayiyana ngayinye zihlanganiswe nemvelo yonke, akunakwenzeka ukuchaza uhlobo lwezinhlayiyana ngayinye, kuphela uhlobo lwesistimu jikelele.

“Kungenxa yokubanjwa kwe-(quantum) ukuthi kungenzeka ukusheshisa inqubo yokushaja ibhethri.” Kusho uDkt Quark.

Kodwa-ke, kusenezinkinga ezimbili ezaziwayo ezingakaxazululiwe ekusetshenzisweni okungokoqobo kwamabhethri e-quantum: ukuhlukaniswa kwe-quantum kanye nesitoreji samandla aphansi.

I-Quantum entanglement inezidingo eziphakeme kakhulu emvelweni, okungukuthi, izinga lokushisa eliphansi kanye nezinhlelo ezizimele. Uhlelo olujwayelekile lwe-quantum aluyona uhlelo oluzimele, futhi akunakwenzeka ukugcina isimo se-quantum isikhathi eside kangaka. Uma nje lezi zimo zishintsha, i-quantum kanye nemvelo yangaphandle izosetshenziswa futhi ukuhambisana kwe-quantum kuzoncishiswa, okungukuthi, umphumela “wokuhlakazeka”, futhi ukuhlanganiswa kwe-quantum kuzonyamalala.

Mayelana nokugcinwa kwamandla kwamabhethri e-quantum, isazi sefiziksi sase-Italy uJohn Gould sathi ngo-2015: “Isitoreji samandla sezinhlelo ze-quantum siyimiyalo eminingana yobukhulu emincane kunaleyo yemishini kagesi yansuku zonke. Sisanda kufakazela ngokombono ukuthi ifaka isistimu. Uma kukhulunywa ngamandla, i-quantum physics ingaletha ukusheshisa. ”

Ngisho noma kusenezinkinga okufanele zixazululwe, uDkt. Quark usazethemba ekusetshenzisweni okungokoqobo kwamabhethri e-quantum. Uthe: “Iningi lezazi zefiziksi kufanele licabange njengami, licabanga ukuthi amabhethri e-quantum awubuchwepheshe bokusebenza esingakwazi ukubuthola ngokugxuma okukodwa’.”

Umgomo wokuqala kaDkt. Quark uwukukhulisa ithiyori yamabhethri e-quantum, kwakhiwe indawo evumela ukuthi kungene i-quantum elabhorethri, nokudala ibhethri lokuqala le-quantum.

Uma esekhuthazwe ngempumelelo ukuze asetshenziswe ngendlela engokoqobo, amabhethri e-quantum azothatha indawo yamabhethri endabuko asetshenziswa kumishini emincane kagesi efana nomakhalekhukhwini. Uma ibhethri lequantum elinomthamo omkhulu owanele lingakhiqizwa, lingasebenzisa izisetshenziswa ezinkulu ezinikezwa amandla avuselelekayo njengezimoto zamandla amasha.
