Itumanaho rya Quantum: molekile, isi idasanzwe na optique

Ikoranabuhanga rya Quantum ni ikoranabuhanga rishya ryamakuru rishingiye ku bukanishi bwa kwant, bukoresha, bubara kandi bwohereza amakuru yumubiri arimosisitemu ya kwant. Gutezimbere no gukoresha ikoreshwa rya tekinoroji yamakuru azatuzanira "imyaka ya kwant", kandi tumenye imikorere myiza yakazi, uburyo bwitumanaho bwizewe hamwe nubuzima bworoshye kandi bubisi.

Imikorere yitumanaho hagati ya sisitemu ya kwant biterwa nubushobozi bwabo bwo gukorana numucyo. Ariko, biragoye cyane kubona ibikoresho bishobora kwifashisha byuzuye kumiterere ya optique.

Vuba aha, itsinda ry’ubushakashatsi mu kigo cya chimie i Paris hamwe n’ikigo cy’ikoranabuhanga cya Karlsruhe hamwe ryerekanye ubushobozi bwa kirisiti ya molekile ishingiye ku isi idasanzwe ya europium ion (Eu³ +) kugira ngo ikoreshwe muri sisitemu ya optique ya optique. Basanze ko ultra-dar linewidth isohora iyi Eu³ + molekulari ya kirisiti ituma imikoranire myiza numucyo kandi ifite agaciro gakomeye muriitumanaho rya kwantna comptabilite.

Igishushanyo 1: Itumanaho rya Quantum rishingiye ku isi idasanzwe ya europium molekulari

Imiterere ya Quantum irashobora kurengerwa, kubwibyo kwant amakuru arashobora kurengerwa. Qubit imwe irashobora icyarimwe guhagararira leta zitandukanye zitandukanye hagati ya 0 na 1, bigatuma amakuru yatunganyirizwa murwego rumwe. Nkigisubizo, imbaraga zo kubara za mudasobwa ya kwant iziyongera cyane ugereranije na mudasobwa gakondo. Ariko, kugirango ukore ibikorwa byo kubara, superbosition ya qubits igomba kuba ishobora gukomeza gushikama mugihe runaka. Mubukanishi bwa kwant, iki gihe cyumutekano kizwi nka coherence ubuzima bwose. Izunguruka za kirimbuzi za molekile zigoye zirashobora kugera kuri superpression hamwe nigihe kirekire cyumye kuko ingaruka zibidukikije kumuzinga wa kirimbuzi zirinzwe neza.

Ntibisanzwe isi ion hamwe na kristu ya kirisiti ni sisitemu ebyiri zakoreshejwe mubuhanga bwa kwant. Ntibisanzwe isi ion ifite ibyiza bya optique na spin, ariko biragoye kubishyiramoibikoresho byiza. Molekula ya kristu iroroshye guhuza, ariko biragoye gushiraho isano yizewe hagati ya spin n'umucyo kuko imirongo isohora imyanda ni nini cyane.

Isi idasanzwe ya kirisiti ya kirisitu yatejwe imbere muri iki gikorwa ihuza neza ibyiza byombi muri ibyo, mu byishimo bya laser, Eu³ + irashobora gusohora fotone itwara amakuru ajyanye no kuzunguruka kirimbuzi. Binyuze mubushakashatsi bwihariye bwa laser, interineti ikora neza ya optique / nucleaire. Hashingiwe kuri ibyo, abashakashatsi barushijeho kumenya urwego rwa kirimbuzi ruzenguruka, kubika hamwe na fotone, hamwe no gukora kwant kwa mbere.

Kubara comptabilite ikora neza, qubits nyinshi zifunze mubisanzwe zirakenewe. Abashakashatsi berekanye ko Eu³ + muri kristu ya molekile yavuzwe haruguru ishobora kugera ku kwangirika kwa kwant binyuze mu guhuza amashanyarazi yataye umurongo, bityo bigafasha gutunganya amakuru ya kwant. Kuberako kristu ya kirisiti irimo isi nyinshi zidasanzwe, ugereranije uburebure bwa qubit burashobora kugerwaho.

Ikindi gisabwa kuri comptabilite ni adresse ya qubits kugiti cye. Tekinike yo gukemura neza muriyi mirimo irashobora kunoza umuvuduko wo gusoma kandi ikabuza kwangiriza ibimenyetso byumuzunguruko. Ugereranije n’ubushakashatsi bwabanjirije iki, guhuza neza kwa kristu ya Eu³ + molekulari ivugwa muri iki gikorwa byatejwe imbere inshuro zigera ku gihumbi, ku buryo ibihugu bizunguruka bya kirimbuzi bishobora gukoreshwa mu buryo bwihariye.

Ibimenyetso bya optique birakwiriye kandi intera ndende ya kwant amakuru yo gukwirakwiza kugirango ihuze mudasobwa ya mudasobwa yo gutumanaho kwa kure. Ibindi bishobora kwitabwaho muguhuza kristu nshya ya Eu³ + molekulari mumiterere ya fotonike kugirango yongere ibimenyetso bimurika. Aka kazi gakoresha isi idasanzwe ya molekile nkibanze kuri enterineti, kandi igatera intambwe yingenzi igana ahazaza hubatswe itumanaho.
