Ko te hangarau mōhiohio kuantum he hangarau mōhiohio hou e hangai ana ki te miihini kuantum, e waehere ana, e tatau ana, e tuku ana hoki i ngā mōhiohio ā-tinana kei rotopūnaha irahikoMā te whanaketanga me te whakamahinga o te hangarau mōhiohio irahiko tātou e kawe ki te "ao irahiko", ā, ka kitea he pai ake te mahi, he haumaru ake ngā tikanga whakawhitiwhiti kōrero, me te noho watea ake, matomato ake hoki.
Ko te whai huatanga o te whakawhitiwhiti kōrero i waenga i ngā pūnaha irahiko e whakawhirinaki ana ki tō rātou kaha ki te taunekeneke ki te mārama. Heoi, he tino uaua ki te kimi i tētahi rauemi ka taea te whakamahi katoa i ngā āhuatanga irahiko o te whatu.
Nō nā tata nei, i whakaatuhia ngātahitia e tētahi rōpū rangahau i te Institute of Chemistry i Parī me te Karlsruhe Institute of Technology te pūmanawa o tētahi tioata ngota i hangaia i runga i ngā iona europium whenua onge (Eu³ +) mō ngā tono i roto i ngā pūnaha irahiko o te whatu. I kitea e rātou ko te tukunga whānui-raina tino whaiti o tēnei tioata ngota Eu³ + ka taea te taunekeneke whai hua ki te mārama, ā, he uara nui tōna i roto i...whakawhitiwhiti kōrero matūme te rorohiko matatini.
Pikitia 1: Te whakawhitiwhiti kōrero matū i runga i ngā tioata ngota europium whenua onge
Ka taea te tāpiri i ngā āhua irahiko, kia taea ai te tāpiri i ngā mōhiohio irahiko. Ka taea e te qubit kotahi te whakaatu i ngā momo āhua rerekē i waenga i te 0 me te 1 i te wā kotahi, ka taea ai te tukatuka i ngā raraunga i roto i ngā puranga. Nō reira, ka piki ake te kaha rorohiko o ngā rorohiko irahiko ki te whakataurite ki ngā rorohiko matihiko tuku iho. Heoi, kia taea ai te mahi i ngā mahi rorohiko, me kaha te pupuri tonu i te taunga o ngā qubit mō tētahi wā. I roto i te miihini irahiko, e mōhiotia ana tēnei wā pumau ko te roanga o te noho tahi. Ka taea e ngā takahuri karihi o ngā ngota matatini te whakatutuki i ngā āhua taunga me ngā roanga roa o te ora maroke nā te mea ka tiakina pai te awe o te taiao ki ngā takahuri karihi.
Ko ngā katote whenua onge me ngā tioata ngota ngā pūnaha e rua kua whakamahia i roto i te hangarau matūriki. He tino pai ngā āhuatanga whatu me te hurihanga o ngā katote whenua onge, engari he uaua ki te whakauru ki roto.ngā taputapu whatuHe māmā ake te whakauru i ngā tioata ngota, engari he uaua ki te whakatū i tētahi hononga pono i waenga i te hurihuri me te mārama nā te mea he whānui rawa ngā roopu tukunga.
Ko ngā tioata ngota ngota whenua onge i whakawhanakehia i tēnei mahi e whakakotahi pai ana i ngā painga o ngā mea e rua, arā, i raro i te whakaoho laser, ka taea e Eu³+ te tuku i ngā photon e kawe ana i ngā mōhiohio mō te takahuri karihi. Mā roto i ngā whakamātautau laser motuhake, ka taea te whakaputa i tētahi atanga takahuri whatu/karihi whai hua. I runga i tēnei kaupapa, i kitea anō e ngā kairangahau te arotau taumata takahuri karihi, te rokiroki ōrite o ngā photon, me te whakahaere i te mahi kuantum tuatahi.
Mō te rorohiko irahiko whai hua, e hiahiatia ana ngā qubit maha e hono ana. I whakaatuhia e ngā kairangahau ka taea e te Eu³+ i roto i ngā tioata ngota i runga ake nei te whakatutuki i te hononga irahiko mā te hononga hiko hē, ā, ka taea ai te tukatuka mōhiohio irahiko. Nā te mea he maha ngā katote whenua onge kei roto i ngā tioata ngota, ka taea te whakatutuki i ngā kiato qubit teitei.
Ko tētahi atu whakaritenga mō te rorohiko matū ko te āheinga ki te wāhitau o ngā qubit takitahi. Ka taea e te tikanga wāhitau whatu i roto i tēnei mahi te whakapai ake i te tere pānui me te ārai i te pokanoa o te tohu ara iahiko. Ki te whakatauritea ki ngā rangahau o mua, kua pai ake te ōritetanga whatu o ngā tioata ngota Eu³+ i pūrongohia i roto i tēnei mahi mā te tata ki te mano ngā wā, kia taea ai te whakarerekē whatu i ngā āhua hurihuri karihi i roto i tētahi huarahi motuhake.
He pai hoki ngā tohu whatu mō te tohatoha mōhiohio irahiko tawhiti hei hono i ngā rorohiko irahiko mō te whakawhitiwhiti irahiko mamao. Tērā pea ka whai whakaaro anō ki te whakaurunga o ngā tioata ngota Eu³+ hou ki roto i te hanganga whakaahua hei whakarei ake i te tohu kanapa. Ka whakamahia e tēnei mahi ngā ngota whenua onge hei pūtake mō te Ipurangi irahiko, ā, ka whai i tētahi taahiraa nui ki ngā hoahoa whakawhitiwhiti irahiko ā muri ake nei.
