Txoj cai ntawm Superposition
Lub hnub nyoog txheeb ze txhais tau tias muaj hnub nyoog sib piv nrog lwm cov pob zeb, txawm tias hluas los yog laus dua. Cov hnub nyoog txheeb ze ntawm pob zeb yog qhov tseem ceeb rau kev nkag siab txog lub ntiaj teb keeb kwm. Cov txheej pob zeb tshiab yeej ib txwm tso rau saum cov pob zeb uas twb muaj lawm. Yog li ntawd, cov khaubncaws sab nraud povtseg yuav tsum muaj ntau dua li cov khaubncaws sab nraud povtseg ze rau saum npoo.
