M\u00f5ned asjad ja n\u00e4htused on nii v\u00e4ikesed, et on raske isegi m\u00f5\u00f5ta, kui v\u00e4ikesed nad on.<\/p>\n

Soome teadlased on n\u00fc\u00fcd v\u00e4lja t\u00f6\u00f6tanud m\u00f5\u00f5teseadme, millega saab m\u00f5\u00f5ta \u00fclimalt \u00fcliv\u00e4ikesi energiahulki.<\/p>\n

Mikko M\u00f6tt\u00f6nen, Andr\u00e1s M\u00e1rton Gunyh\u00f3 ja nende kolleegid Aalto \u00dclikoolist Espoos kirjutavad ajakirjas Nature Electronics<\/a>, et nende seade suudab registreerida energia, mida kannavad hulga peale kokku v\u00e4hem kui 200 mikrolaine footonit.<\/p>\n

See on kujuteldamatult v\u00e4ike energia, arvuliselt v\u00e4ljendudes v\u00e4iksem kui \u00fcks zeptod\u017eaul. Niisugune imepisike energiakogus on veel miljon miljonit korda v\u00e4iksem kui n\u00e4iteks vaid \u00fche millimeetri k\u00f5rguselt kukkunud liivaterakese energia.<\/p>\n

<\/p>\n

P\u00f5him\u00f5tteliselt v\u00f5tsid teadlased \u00fcliv\u00e4ikese metalltraadi, jahutasid selle peaaegu absoluutse nullini ja lasid selle peale siis natuke mikrolainekiirgust, aga m\u00e4rksa k\u00f5rgemasageduslikku ja v\u00e4iksemalainepikkuselist kui kodumajapidamises ette tulla v\u00f5ivas ahjus tavaks. Selle v\u00f5rra olid siis kiirguse footonidki m\u00f5nev\u00f5rra suurema energiaga.<\/p>\n

Kullast ja pallaadiumist nanotraati tabanud footonid andsid traadile energiat ja traat l\u00e4ks igast footonist \u00f5ige pisut soojemaks.<\/p>\n

Umbes 170-footonilise tabamuse peale tekkinud \u00fclikerget soojenemist suutsidki teadlased juba m\u00f5\u00f5ta.<\/p>\n

Selleks oli neil traadi k\u00fclge pandud v\u00e4ike elektroonikaskeem, ostsillaator, milles kulgenud elektrivoolu v\u00f5nkesagedus soojenemise peale natuke muutus.<\/p>\n

Seda muutust suutsid teadlased veelgi selgemini m\u00e4\u00e4rata matemaatilise andmet\u00f6\u00f6tlusv\u00f5tte abil, mis eraldas signaali m\u00fcrast 30 protsenti t\u00e4psemini kui tavap\u00e4rasemad meetodid seda teinuksid.<\/p>\n

Teadlased loodavad, et nende seadmega saab p\u00f5him\u00f5tteliselt tuvastada veelgi v\u00e4iksemaid footonihulki ja energiakoguseid.<\/p>\n

Kui aga seadet t\u00e4iustada, n\u00e4iteks asendada nanotraat grafeenit\u00fckiga ja t\u00f5sta elektroonikaskeemi tundlikkust, v\u00f5iks saada m\u00f5\u00f5tma hakata lausa \u00fcksikuid mikrolainefootoneid.<\/p>\n

Juba enne seda v\u00f5ivad enneolematult t\u00e4psed m\u00f5\u00f5tmised aga kasuks tulla kvantarvutites, et kvantbittide olekut paremini seirata, v\u00f5i tumeaineotsingute f\u00fc\u00fcsikas, et avastada aksoneid, seni vaid teoreetiliselt aimatavaid osakesi.<\/p>\n
