Canada coj txoj hauv kev mus rau quantum yav tom ntej

Lub tuam txhab Canadian D-Wave yog ib kauj ruam ze dua los ua pov thawj qhov siv tau ntawm lawv lub computer quantum D-Wave Ob. Cov txiaj ntsig ntawm kev sim qhia pom cov cim ntawm quantum kev ua haujlwm hauv lub computer tsis ntev los no tau luam tawm hauv Physical Review X, ib phau ntawv tshuaj xyuas cov phooj ywg.

Tab sis dab tsi yog quantum computer?

Lub quantum computer ua raws li cov cai ntawm quantum physics, uas yog, physics ntawm ib theem me me. Cov me me coj txawv txawv dua li cov khoom siv niaj hnub peb pom. Qhov no ua rau lawv zoo dua li cov qauv computers, uas ua raws li cov cai ntawm classical physics.

Piv txwv li, koj lub laptop ua cov ntaub ntawv raws li cov khoom: sib law liag lossis ib qho. Quantum computers siv qubits uas, ua tsaug rau qhov kev tshwm sim quantum hu ua "superposition," tuaj yeem yog xoom, ib qho, lossis ob qho tib si ib txhij. Txij li thaum lub khoos phis tawj tuaj yeem ua tiav txhua qhov kev xaiv tau ib zaug, nws nrawm dua li koj lub khoos phis tawj tuaj yeem ua tau.

Cov txiaj ntsig ntawm qhov nrawm no tau pom meej thaum daws teeb meem kev lej nyuaj uas muaj cov ntaub ntawv ntau dhau los ua kom dhau los ntawm cov qauv siv.

Quantum Critics

Lub tuam txhab British Columbia tau muag nws cov khoos phis tawj rau Lockheed Martin, Google, thiab NASA txij li xyoo 2011. Qhov kev saib xyuas loj no tsis tau tso tseg cov neeg tsis ntseeg los ntawm kev thuam lub tuam txhab cov lus thov. Scott Aaronson, tus xibfwb ntawm Massachusetts Institute of Technology, yog ib lub suab nrov tshaj plaws ntawm cov no.

Ntawm nws qhov blog, Aaronson hais tias D-Wave cov lus thov "tsis muaj kev txhawb nqa los ntawm cov pov thawj tam sim no." Thaum nws lees tias lub khoos phis tawj siv cov txheej txheem quantum, nws taw qhia tias qee lub khoos phis tawj txheem tau ua tiav D-Wave Ob. Nws lees tias D-Wave tau ua tiav, tab sis hais tias lawv "cov lus thov ... yog qhov hnyav dua li qhov ntawd."

Canada's Quantum Legacy

D-Wave lub khoos phis tawj tsis yog tib qho kev nce qib hauv quantum physics los hnav lub cim Canadian.

Nyob rau hauv 2013, encoded qubits tseem nyob rau hauv chav tsev kub rau ze li ntawm 100 lub sij hawm ntev dua puas tau ua ntej. Pab pawg thoob ntiaj teb uas ua tiav cov txiaj ntsig tau coj los ntawm Mike Thewalt ntawm Simon Fraser University hauv British Columbia.

Hauv Waterloo, Ont., Raymond Laflamme, tus thawj coj ntawm Lub Tsev Haujlwm rau Quantum Computing (IQC), tau tshaj tawm cov khoom siv hluav taws xob photon uas siv quantum technology. Nws lub hom phiaj tom ntej rau lub chaw yog los tsim kom muaj lub tswv yim, thoob ntiaj teb quantum computer. Tab sis cov cuab yeej zoo li no tuaj yeem ua tau li cas?
