Peb yog ib kauj ruam los ze zog mus quantum computers tom qab lub Australian txhob

Engineers nyob rau University of New South Wales (Australia) yog ib qho tseem ceeb txhob uas ua rau quantum computers ib kauj ruam ze zog mus rau kev muaj tiag.

Lub peculiarity ntawm quantum computers

Cov pab neeg tsim ib quantum version ntawm ib tus qauv computer code nyob rau hauv ib tug silicon nti. Qhov no qhia tau hais tias txhob hais tias nws yog tau los mus tsim robust quantum computers.

Cov computers muaj lub peev xwm mus daws tau cov teeb meem sai npaum li cas tshaj tej uas twb muaj lawm hnub no. Nws combines cov kev cai ntawm lub computer science thiab qhov tshwm sim ntawm quantum mechanics, uas yog tsis tau cai nyob rau hauv lub neej txhua hnub. Qhov ntawd yog lub hauv paus ntsiab ntawm superposition, uas twb popularized los ntawm Schrodinger, thiab tsis meej pem.

Lub hauv paus ntsiab lus ntawm quantum entanglement

Test ua nyob rau hauv teb chaws Australia, siv lub hauv paus ntsiab lus ntawm quantum entanglement khiav code. Entangled hais raug tsim ua ke nyob rau hauv ib tug txiav txim, yog li ntawd lawv lub zog xws li lub zog thiab momentum txuam. Yog hais tias cov cuab yeej yog hloov mus rau ib tug particle, piv txwv li thaum lub sij hawm cov kev ntsuas, lub lwm yuav kuj muaj cuam tshuam. Cov kev hloov tshwm sim tam sim ntawd, txawm yog hais tias tus hais yog nyob rau ntawm opposite xaus ntawm lub ntug, li ntawd, zaum ntseeg tias tej zaum nws yuav tsum yog ib tug ua txhaum ntawm qhov tshwj xeeb kev tshawb xav ntawm Relativity, raws li uas cov ntaub ntawv yuav tsis mus sai dua lub teeb. Txawm hais tias nws twb nyuam qhuav pom tau hais tias tsis meej pem - nws yog ib tug tiag tiag tshwm sim.

Siv quantum cwj pwm ntxiv laij tuition. Nws yog, nyob rau hauv ib lub siab, yuav hu ua ib tug ua ntawm yog vim li cas quantum computers yuav ua tau ntau haib. Cov tib tooj ntawm cov khoom tso cai rau koj sau computer code, uas muaj ib tug ntau ntau lo lus. Lawv muaj peev xwm yuav siv tau los khiav ib tug txawv algorithm, uas nce mus txog cov kev tshwm sim muaj tsawg kauj ruam.

Lub essence ntawm qhov xyaum ua tej

Thaum lub sij hawm xyaum ua tej yam, zaum tau entangled lub xeev tus phosphorus atom (nws nucleus) thiab ib zaug xwb electron nyob rau hauv lub pob zeb ntais nti. Lawv tsim ib tug qubit - ntsis quantum computer caij. Zaum tau pom hais tias lawv yuav ua tau yooj yim los tswj thiab siv. Nyob rau hauv ib tug raug me ntsis ntawm ob lub xeev - 0 los yog 1. Ib tug qubit kuj muaj ib tug ntau heev, ua tsaug rau quantum mechanics. Uas yog vim li cas nws yuav tsum hais tias quantum computers yuav muaj ntau haib tshaj niaj hnub no txoj kev.

Australian zaum tau muaj pov thawj hais tias lawv muaj peev xwm sau cov cai nyob rau hauv lub ntaus ntawv uas tsa ib tug niaj hnub silicon chips rau laptops los yog cov xov tooj txawb. Qhov no yog ib tug tiag tiag kev kovyeej ntawm hluav taws xob engineering.
