Understand

From the viewpoint of no-cloning theorem we postulate a relation between the current accelerated expansion of our universe and the inflationary expansion in the very early universe.

It implies that the fate of our universe should be in a state with accelerated expansion.
Quantitatively we find that the no-cloning theorem leads to a lower bound on the cosmological constant which is compatible with observations.

For a finite size system whose total number of degrees of freedom scales with a parameter N N , such a system is called “fast scrambler” if the time for the thermalization saturates t ∗ ≳ T − 1 ln ⁡ N t_{*}\gtrsim T^{-1}\ln N . Here T T is the temperature
