Izazinzulu zinika ingxelo yokwenziwa kweepolaritons zemata-wave kwilathisi yokukhanya, ukufunyanwa kovavanyo olwenza ukuba kuphononongwe ubungakanani obuphakathi besayensi kunye nethekhnoloji paradigm ngokulinganisa ubungakanani obuthe ngqo kusetyenziswa iiathom ze-ultracold.
Ukufunyanwa kweMatter-Wave Polaritons kuKhanya okutsha kwiTekhnoloji yeFotonic yeQuantum
Uphando olupapashwe kwiphephancwadi iNature Physics lubonelela ngeqonga elinoveli 'lesecond quantum revolution.'
Uphuhliso lwamaqonga okulinga aqhubela phambili icandelo lenzululwazi nobuchwepheshe bequantum (QIST) iza neseti eyodwa yeenzuzo kunye nemingeni eqhelekileyo kubo nabuphi na ubugcisa obuvelayo. Abaphandi kwiYunivesithi yaseStony Brook, ekhokelwa nguDominik Schneble, PhD, baxela ukubunjwa kwe-polaritons ye-mata-wave kwi-lattice optical, ukufunyanwa kovavanyo oluvumela izifundo ze-paradigm ye-QIST ephakathi ngokusebenzisa ukulinganisa kwe-quantum ngokuthe ngqo usebenzisa i-athomu ze-ultracold. Izazinzulu ziqikelela ukuba iinoveli zazo zequasiparticles, ezilinganisa ngamandla iifotoni ezisebenzisanayo kwimathiriyeli kunye nezixhobo kodwa zithintele eminye yemiceli mngeni ekhoyo, ziya kuxhamla kuphuhliso oluqhubekayo lwamaqonga e-QIST alungele ukuguqula itekhnoloji yekhompyuter kunye nonxibelelwano.
Iziphumo zophando zichazwe kwiphepha elipapashwe kwijenali IFizikiki yendalo.
Uphononongo lunika ukukhanya kwiipropathi ezisisiseko ze-polariton kunye nezinto ezinxulumene nemizimba emininzi, kwaye ivula amathuba amatsha kwizifundo zomba we-polaritonic quantum.
Umceli mngeni obalulekileyo ekusebenzeni kunye neeplatifti ze-QIST ezisekelwe kwifoton kukuba ngelixa iifotoni zinokuba ngabathwali abafanelekileyo bolwazi lwe-quantum abaqhelekanga ukusebenzisana. Ukungabikho konxibelelwano olunjalo kwakhona kuthintela utshintshiselwano olulawulwayo lolwazi lwe-quantum phakathi kwabo. Izazinzulu ziye zafumana indlela yokujikeleza oku ngokudibanisa iiphoton kwi-excitetions enzima kwizinto, ngaloo ndlela zenza ii-polaritons, i-chimera-like hybrids phakathi kokukhanya kunye nento. Ukungqubana phakathi kwezi quasiparticles zinzima ke zenza ukuba kwenzeke ukuba iifotoni zisebenze ngokufanelekileyo. Oku kunokwenza ukuphunyezwa kwe-photon-based quantum gate operations kwaye ekugqibeleni isiseko se-QIST siphela.
Nangona kunjalo, umceli mngeni omkhulu kubomi obunqamlekileyo bezi polaritons ezisekelwe kwiifotoni ngenxa yokudibanisa kwazo okunemitha kwindalo engqongileyo, okukhokelela ekuboleni okungalawulekiyo okuzenzekelayo kunye nokunyaniseka.
Unikezelo lobugcisa lweziphumo zophando kuphononongo lwe-polariton lubonisa ii-athom kwileti yokubona zenza isigaba sokugquma (ekhohlo); iiathom ezijika zibe ziipolaritons zemaza ngokudibanisa ivacuum elamlwa yimitha yemicrowave emelwe ngumbala oluhlaza (embindini); iipolaritons ziyashukuma kwaye zenze inqanaba elingaphezu kwamanzi okudibanisa okuqinileyo (ngasekunene).

Ngokutsho kukaSchneble kunye noogxa, uphando lwabo olupapashiweyo lwe-polariton luyithintele imida enjalo ebangelwa ukubola okuzenzekelayo ngokupheleleyo. Imiba ye-photon yee-polaritons zabo zithwalwa ngokupheleleyo ngamaza e-athomu, apho iinkqubo zokubola ezingafunekiyo azikho. Olu phawu luvula ukufikelela kwiinkqubo zeparameter ezingekabikho, okanye ezingekafikeleleki, kwiinkqubo ze-photon-based polaritonic.
"Uphuhliso lwe-quantum mechanics lulawula kwinkulungwane edlulileyo, kwaye 'inguqu yesibini ye-quantum' ekuphuhliseni i-QIST kunye nezicelo zayo ngoku ziyaqhubeka kwihlabathi jikelele, kubandakanywa neenkampani ezifana ne-IBM, i-Google ne-Amazon," kusho uSchneble, uNjingalwazi kwiSebe leFiziksi kunye neNkwenkwezi kwiKholeji yoBugcisa kunye neSayensi. "Umsebenzi wethu uqaqambisa ezinye iziphumo ezisisiseko ze-quantum mechanical quantum ezinomdla kwiinkqubo ze-photonic quantum kwi-QIST ukusuka kwi-semiconductor nanophotonics ukuya kwi-circuit quantum electrodynamics."
Abaphandi baseStony Brook baqhube imifuniselo yabo ngeqonga elineathom ezipholileyo kwilathisi ebonakalayo, indawo enokubakho efana neqanda-ikreyiti eyenziwe ngamaza okukhanya amileyo. Besebenzisa isixhobo sokufunxa esizinikezeleyo esinee-lasers ezahlukeneyo kunye nemimandla yolawulo kwaye sisebenza kubushushu be-nanokelvin, baphumeze imeko apho iiathom zivaleleke kwiletisi “zinxibe” ngokwazo ngamafu ezinto zokufunxa ezenziwe ngamaza athambileyo, aphumayo.
Iqela lifumene ukuba, ngenxa yoko, amasuntswana e-polaritonic ahamba kakhulu. Abaphandi bakwazi ukukhangela ngokuthe ngqo ubume babo bangaphakathi ngokugungqa ngobunono i-lattice, ngaloo ndlela bafikelele kwiminikelo yomcimbi wamaza kunye ne-atomic lattice excitation. Xa ishiywe yodwa, i-mata-wave polaritons ixhuma kwi-lattice, isebenzisana enye kwenye, kwaye yenze izigaba ezizinzileyo ze-quasiparticle matter.
"Ngovavanyo lwethu senze ukulinganisa kwe-quantum yenkqubo ye-exciton-polariton kulawulo lwenoveli," kuchaza uSchneble. “Ukufuna ukwenza njalo analogue’ simulations, which in addition areI-analog` ngengqiqo yokuba iiparamitha ezifanelekileyo zinokudayilwa ngokukhululekileyo, ngokwayo zenza umkhombandlela obalulekileyo ngaphakathi kwe-QIST.
