Quantum kutaurirana: mamorekuru, zvisingawanzo pasi uye optical

Quantum ruzivo tekinoroji inyanzvi yeruzivo tekinoroji yakavakirwa pa quantum mechanics, inokodha, compute uye kuendesa ruzivo rwemuviri rwuri mukati.quantum system. Iko kuvandudza uye kushandiswa kwehuwandu hweruzivo tekinoroji kuchatiunza mu "quantum zera", uye toona kushanda kwepamusoro, nzira dzakachengeteka dzekutaurirana uye mararamiro ari nyore uye egirinhi.

Kubudirira kwekukurukurirana pakati pe quantum systems kunoenderana nekukwanisa kwavo kuwirirana nechiedza. Nekudaro, zvakanyanya kuoma kuwana chinhu chinogona kutora mukana wakazara weiyo quantum zvimiro zve optical.

Munguva pfupi yapfuura, boka rekutsvagisa kuInstitute of Chemistry muParis neKarlsruhe Institute of Technology pamwe chete vakaratidza kugona kwekristaro yemamorekuru yakavakirwa pane isingawanzo pasi europium ions (Eu³ +) yekushandiswa muhuwandu hwemasystem emaziso. Vakaona kuti iyo yekupedzisira-yakamanikana linewidth emission yeiyi Eu³ + molecular crystal inogonesa kusangana kwakanaka nechiedza uye ine kukosha kwakakosha mu.quantum kutauriranauye quantum computing.


Mufananidzo 1: Quantum kutaurirana kunobva pane isingawanzo pasi europium molecular crystals

Quantum inoti inogona kukwiridzirwa, saka ruzivo rwehuwandu hunogona kukwidziridzwa. Imwe qubit inogona panguva imwe chete kumiririra nyika dzakasiyana siyana pakati pe0 ne1, ichibvumira data kuti igadziriswe mukuwirirana mumabhechi. Nekuda kweizvozvo, iyo komputa simba yemakomputa equantum ichawedzera zvakanyanya kana ichienzaniswa neyechinyakare madhijitari makomputa. Nekudaro, kuitira kuti uite macomputer mashandiro, iyo superposition yequbits inofanirwa kugona kuramba yakatsiga kwenguva yakati rebei. Mune quantum mechanics, iyi nguva yekugadzikana inozivikanwa seyakabatana hupenyu hwese. Iyo nyukireya spins yemamorekuru akaomesesa anogona kuwana superposition nyika nehupenyu hurefu hwakaoma nekuti pesvedzero yezvakatipoteredza panyukireya spins inodzivirirwa zvinobudirira.

Rare Earth ions uye molecular crystals ndiwo maviri masisitimu akashandiswa muquantum tekinoroji. Rare Earth ions ine yakanakisa optical uye spin zvivakwa, asi yakaoma kubatanidzwa mukatioptical devices. Molecular crystals ari nyore kubatanidza, asi zvakaoma kumisa hukama hwakavimbika pakati pe spin uye chiedza nekuti mabhendi ekubudisa akawandisa.

Iwo asingawanzo pasi mamorekuru makristasi akagadzirwa mubasa iri anonyatso batanidza zvakanakira zvese mune izvo, pasi pe laser excitation, Eu³ + inogona kuburitsa mafotoni akatakura ruzivo nezve nyukireya spin. Kuburikidza nemiedzo chaiyo yelaser, inobudirira optical/nuclear spin interface inogona kugadzirwa. Pahwaro uhwu, vaongorori vakawedzera kuona nyukireya spin level yekutaura, kuchengetedza kwakabatana kwemafotoni, uye kuitwa kwekutanga quantum oparesheni.

Kuti iite inoshanda quantum computing, akawanda akapinzwa qubits anowanzo kudiwa. Vatsvagiri vakaratidza kuti Eu³ + mune ari pamusoro mamorekuru makristasi anogona kuwana quantum entanglement kuburikidza neakarasika magetsi ekubatanidza munda, zvichigonesa quantum ruzivo rwekugadzirisa. Nekuti makristasi emamorekuru ane akawanda asingawanzo pasi ion, yakakwira qubit densities inogona kuwanikwa.

Chimwe chinodiwa kune quantum computing ndeyekugadziriswa kwemunhu qubits. Iyo optical addressing technique mubasa iri inogona kuvandudza kukurumidza kuverenga uye kudzivirira kupindira kwechiratidzo chedunhu. Kuenzaniswa nezvidzidzo zvakapfuura, kubatana kwemaziso kweEu³ + makristasi emamorekuru akataurwa mubasa iri anovandudzwa nekanenge chiuru, kuitira kuti nyukireya inotenderera nyika inogona kushandiswa nenzira yakananga.

Masaini masaini akakodzerawo kureba-kure quantum ruzivo rwekugovera kubatanidza quantum makomputa kune kure kure quantum kutaurirana. Kumwe kufunga kunogona kupihwa kubatanidzwa kweEu³ + mamorekuru makristasi muchimiro chefotonic kusimudzira chiratidzo chinopenya. Iri basa rinoshandisa zvisingawanzo pasi mamorekuru sehwaro hwehuwandu hweInternet, uye rinotora danho rakakosha kune ramangwana quantum kutaurirana zvivakwa.
