Ibikoresho bya rukuruzi byarenze amateka yo guhinduranya vuba cyane

Abashakashatsi bo muri CRANN (Ikigo cy’Ubushakashatsi ku miterere ya Nano n’ibikoresho bihindagurika), hamwe n’Ishuri rya Fiziki muri Trinity College Dublin, uyu munsi batangaje koibikoresho bya rukuruziyakozwe muri Centre igaragaza uburyo bwo guhinduranya rukuruzi bwihuta cyane kurusha ubundi bwose bwakozwe.

Itsinda ryakoresheje sisitemu ya laser ya femtosecond muri Laboratwari y’Ubushakashatsi ya Photonics muri CRANN kugira ngo rihindure hanyuma rihindure icyerekezo cya rukuruzi cy’ibikoresho byaryo mu buryo bwa trillionths y’isegonda, ryihuse inshuro esheshatu kurusha iryari risanzwe, kandi ryihuse inshuro ijana kurusha umuvuduko w’isaha ya mudasobwa bwite.

Ubu buvumbuzi bwerekana ubushobozi bw'ibikoresho mu kongera gukoresha mudasobwa zikoresha ingufu zihuta cyane ndetse n'uburyo bwo kubika amakuru.

Abashakashatsi bagezeho umuvuduko wabo udasanzwe wo guhindura ibintu mu buryo budasanzwe mu cyuma cyitwa MRG, cyakozwe bwa mbere n'itsinda mu 2014 kiva muri manganese, ruthenium na gallium. Mu igerageza, itsinda ryakoze amashusho magufi ya MRG rikoresheje urumuri rutukura rwa laser, rutanga megawati z'ingufu mu gihe kitarenze kimwe cya miliyari y'isegonda.

Ihindagurika ry'ubushyuhe rihindura icyerekezo cya rukuruzi cya MRG. Bisaba igice cya cumi cya picosegonda yihuta cyane kugira ngo habeho iri hinduka rya mbere (1 ps = kimwe cya tiriyari imwe y'isegonda). Ariko, ikirenzeho, itsinda ryavumbuye ko rishobora kongera guhindura icyerekezo nyuma ya tiriyari 10 z'isegonda. Uku niko kongera guhindura icyerekezo cya rukuruzi byigeze kugaragara.

Ibisubizo byabo byasohotse muri iki cyumweru mu kinyamakuru gikomeye cya fiziki, Physical Review Letters.

Uku kuvumbura gushobora gufungura inzira nshya zo guhanga udushya mu ikoranabuhanga rya mudasobwa n'amakuru, bitewe n'akamaro koibikoresho bya rukuruzimuri uru rwego. Ibikoresho bya rukuruzi byihishe mu bikoresho byacu byinshi by'ikoranabuhanga, ndetse no mu bigo binini by'amakuru biri mu mutima wa interineti, bisoma kandi bikabika amakuru. Ikwirakwira ry'amakuru ririho ubu ritanga amakuru menshi kandi rigakoresha ingufu nyinshi kurusha mbere hose. Gushaka uburyo bushya bwo gukoresha ingufu neza bwo gukoresha amakuru, n'ibikoresho bihuye, ni ubushakashatsi bwibanda ku isi yose.

Impamvu nyamukuru yatumye amakipe ya Trinity atsinda ni ubushobozi bwo kugera ku guhinduranya vuba nta ngufu za rukuruzi. Guhinduranya rukuruzi bisanzwe bikoresha indi rukuruzi, ikiguzi cyabyo haba mu ngufu no mu gihe. Hamwe na MRG, guhinduranya byagezweho hakoreshejwe ubushyuhe, hifashishijwe uburyo bwihariye bw’ibikoresho n’urumuri.

Abashakashatsi ba Trinity Jean Besbas na Karsten Rode baganira ku buryo bumwe bw'ubushakashatsi:

"Ibikoresho bya rukuruzis mu by’ukuri ifite ububiko bushobora gukoreshwa muri logique. Kugeza ubu, guhindura uva kuri 'logical 0' imwe ujya kuri 'logical 1' byari bikeneye ingufu nyinshi kandi bigatinda cyane. Ubushakashatsi bwacu bwibanze ku muvuduko werekana ko dushobora guhindura MRG tuva kuri 'state' imwe tujya kuri indi mu masegonda 0.1 kandi icy’ingenzi ni uko guhindura urundi ruhererekane rushobora gukurikiraho nyuma y’amasegonda 10 gusa, bihuye n’umuvuduko w’imikorere wa ~ 100 gigahertz - vuba kurusha ikindi kintu cyose cyagaragaye mbere.

“Ivumburwa ryerekana ubushobozi bwihariye bwa MRG yacu bwo guhuza urumuri no kuzenguruka neza kugira ngo tubashe kugenzura rukuruzi hamwe n’urumuri hamwe n’urumuri hamwe n’ingufu ku gihe kitari kigerwaho kugeza ubu.”

Avuga ku kazi k'ikipe ye, Porofeseri Michael Coey, Ishuri rya Fiziki rya Trinity na CRANN, yagize ati: “Mu 2014 ubwo njye n'ikipe yanjye twatangazaga bwa mbere ko twakoze ifumbire nshya ya manganese, ruthenium na gallium, izwi nka MRG, ntitwigeze dukeka ko iyo mashini ifite ubushobozi butangaje bwa magneto-optical.

“Iyi myigaragambyo izayobora ku bitekerezo bishya by’ibikoresho bishingiye ku mucyo na rukuruzi bishobora kungukira mu kongera umuvuduko n’ingufu, wenda amaherezo bikazagera ku gikoresho kimwe rusange gifite imikorere ihuriweho yo kwibuka no gukoresha logique. Ni ikibazo gikomeye, ariko twagaragaje ibikoresho bishobora gutuma bishoboka. Twizeye kubona inkunga n’ubufatanye mu nganda kugira ngo dukomeze akazi kacu.”
