Kutaurirana kweQuantum: mamorekuru, rare earths uye optical

Tekinoroji yeruzivo yeQuantum tekinoroji itsva yeruzivo yakavakirwa pa quantum mechanics, iyo inoronga, inoverenga uye inotumira ruzivo rwepanyama rwuri musisitimu yekwantumuKuvandudzwa nekushandiswa kwetekinoroji yeruzivo rwe quantum kuchatisvitsa mu "nguva ye quantum", uye kuchaita kuti basa rive rakanaka, nzira dzekutaurirana dzakachengeteka uye mararamiro ari nyore uye akarongeka.

Kushanda zvakanaka kwekutaurirana pakati pema quantum systems kunoenderana nekukwanisa kwavo kutaurirana nechiedza. Zvisinei, zvakaoma kuwana chinhu chinogona kushandisa zvizere hunhu hwe quantum hwe optical.

Munguva pfupi yapfuura, chikwata chekutsvagisa paInstitute of Chemistry muParis neKarlsruhe Institute of Technology pamwe chete vakaratidza kugona kwekristaro yemamorekuru yakavakirwa pa rare earth europium ions (Eu³ +) mukushandiswa muma quantum systems e optical. Vakaona kuti kubuda kwe ultra-narrow linewidth kweiyi Eu³ + molecular crystal kunoita kuti kudyidzana nechiedza kushande zvakanaka uye kune kukosha kwakakosha mukutaurirana kwequantumuye quantum computing.

Mufananidzo 1: Kutaurirana kweQuantum kwakavakirwa pa rare earth europium molecular crystals

MaQuantum anogona kuiswa pamusoro, saka ruzivo rwequantum runogona kuiswa pamusoro. Qubit imwe chete inogona kumiririra panguva imwe chete mamiriro akasiyana-siyana ari pakati pe0 ne1, zvichibvumira data kuti rigadziriswe zvakaenzana mumabatch. Nekuda kweizvozvo, simba remakombiyuta equantum richawedzera zvakanyanya zvichienzaniswa nemakombiyuta edhijitari echinyakare. Zvisinei, kuti iite mashandiro ekuverenga, superposition yequbits inofanira kukwanisa kuramba iripo kwenguva yakati rebei. Mu quantum mechanics, nguva iyi yekugadzikana inozivikanwa sehupenyu hwekubatana. Kutenderera kwenyukireya kwemamorekuru akaomarara kunogona kuita superposition states nehupenyu hurefu hwemvura nekuti pesvedzero yezvakatipoteredza pakuputika kwenyukireya inodzivirirwa zvinobudirira.

Maion earth rare nemacrystals emamorekuru ndiwo masystem maviri akashandiswa mu quantum technology. Maion earth rare ane hunhu hwakanaka hwe optical ne spin, asi akaoma kubatanidzwa muzvishandiso zvemaziso. Makristasi emamorekuru ari nyore kubatanidza, asi zvakaoma kusimbisa hukama hwakavimbika pakati pekutenderera nechiedza nekuti mabhendi ekuburitsa mweya akafara zvakanyanya.

Makristaro emamorekuru epasi asingawanzoonekwi akagadzirwa mubasa iri anobatanidza zvakanaka zvese zviri zviviri nekuti, pasi pekukwezvwa nelaser, Eu³ + inogona kuburitsa maphoton ane ruzivo nezve nuclear spin. Kuburikidza nekuyedza kwakanangana nelaser, interface inoshanda ye optical/nuclear spin inogona kugadzirwa. Pachikonzero ichi, vaongorori vakaenderera mberi nekuona kuti nuclear spin level inotarisa sei, kuchengetedza maphoton kwakabatana, uye kuita kwekutanga kwe quantum operation.

Kuti pave nekushanda zvakanaka kwe quantum computing, ma qubits akawanda anowanzo diwa. Vaongorori vakaratidza kuti Eu³ + muma crystals emolecular ari pamusoro apa anogona kuwana quantum entanglement kuburikidza ne stray electric field coupling, zvichiita kuti ruzivo rwe quantum rugadziriswe. Nekuti ma crystals emolecular ane ma ions akawanda e rare earth, qubit densities yakakwira inogona kuwanikwa.

Chimwe chinodiwa pakuverenga kwequantum ndiko kugona kupindura kweQubits imwe neimwe. Nzira yekutarisa maOptical mubasa iri inogona kuvandudza kumhanya kwekuverenga uye kudzivirira kupindira kwechiratidzo chedunhu. Zvichienzaniswa nezvidzidzo zvekare, kubatana kwemaOptical kwemaCrystals eEu³ + akataurwa mubasa iri kwakavandudzwa kanenge ka1000, kuitira kuti mamiriro eNuclear Spin agone kushandiswa neOptical nenzira chaiyo.

Zviratidzo zvemaziso zvakakodzerawo pakugoverwa kwemashoko e quantum kure kuti ubatanidze makomputa e quantum kuti akwanise kutaurirana ne quantum kure. Kufunga kwakawanda kunogona kupihwa pakubatanidzwa kwemakristaro matsva eEu³ + molecular muchimiro che photonic kuti kuwedzere chiratidzo chinopenya. Basa iri rinoshandisa mamorekuru epasi rare sehwaro hwe quantum Internet, uye rinotora danho rakakosha kune magadzirirwo ekutaurirana kwe quantum mune ramangwana.
