Kvantno računalo objašnjenje: što je i što zaista može

Dokumentarac prati otvaranje dilucijskog rashladnog uređaja ohlađenog na 10 milikelvin i objašnjava što se nalazi na dnu: čip s kvantnim procesorom veličine nokta. Gledalac saznaje kako Josephsonov spoj od jednog nanometra omogućuje qubit, zašto je korekcija grešaka ključni problem i što su Google i IBM stvarno dokazali 2024. godine. Bez obećanja koja se ne mogu potkrijepiti — samo dokumentirani rezultati i otvorena pitanja.
