Consequently, the world quantum computerized,
Das ermöglichte die
Verbreitung von Quantencomputern
y el mundo se volvió
un ordenador cuántico.
y el mundo se volvió
un ordenador cuántico.
et le monde
devint un ordinateur quantique
per far sì che i mondi paralleli
 potessero interagire fra loro.
o mundo por completo adota
os computadores quânticos
В итоге весь мир стал единым
квантовым компьютером.
