Umakanika kwanta

anahesabika kuwa baba wa nadharia ya kwanta.]]
**Umakanika kwanta** (kwa Kiingereza: *Quantum mechanics*; kifupi: **QM**) ni sehemu ya fizikia inayoeleza jinsi vitu vinavyounda atomi na mawimbi ya sumakuumeme (kama vile nuru) vinavyofanya kazi. Hivyo umakanika kwanta huchunguza vitu tusivyoviona, kwa mfano kutokana na udogo wake, au vinavyosogea kasi mno, tofauti na vile vinavyochunguzwa na umakanika kawaida, sehemu ya kwanza ya umakanika. *Kwanta* katika fizikia ni kiwango cha chini kabisa cha kipimo chochote cha kiumbo kinachohusika katika maingiliano. 

Nadharia inayoelezea kwanta katika fizikia inaitwa *nadharia ya kwanta* na inazungumza kwamba vipimo vyovyote vya kiumbo vyawezavyo kupimwa hadi kiwango cha chini kabisa cha kwanta, kwa mfano: kiwango cha chini kabisa cha mwanga ni ukubwa wa fotoni, na kiwango cha chini kabisa cha chaji ni chaji ya elektroni.

## Uvutano kwanta 
Kufahamu jinsi umakanika kwanta na nadharia ya uhusianifu zinavyoweza kuunganishwa kumejenga uwanja mpya wa utafiti wa uvutano kwanta. Uvutano kwanta unajaribu kutoa nadharia inayounganisha uvutano na sheria za umakanika kwanta ili kuelewa nguvu za uvutano katika kiwango cha chembe.

Katika utafiti huu, watafiti wanajaribu kuelewa nadharia ya "loop quantum gravitiy" (LQG), ambayo inadai kwamba nafasiwakati haiko kama kiti cha kimiminika, bali kinaundwa na vidogo vya kwanta. Hii ni tofauti na dhana ya kimapokeo ya nafasiwakati kama kipengele cha nene na kisicho na mwisho. Aidha, kuna nadharia ya kamba (Kiingereza: "string theory") ambayo inadhani kuwa chembe ndogo za msingi haziko kama chembe za kawaida, bali ni kamba za nishati ambazo hupiga mawimbi.
