Quantum information theory: Quantum complexity grows linearly for an exponentially long time Date: March 28, 2022 Source: Helmholtz-Zentrum Berlin für Materialien und Energie Summary: Physicists ...

The first section of the paper deals with linear operators Ti: U→ V,i=1,...,n, where U and V are vector spaces over an infinite field, such that for every u∈ U, the vectors T1u,...,Tnu are linearly ...

We prove that the problem of determining the minimum propositional proof length is NP- hard to approximate within a factor of 2 log1 - o (1)n. These results are very robust in that they hold for ...

Researchers are now suggesting that male and female lifespans continue to increase linearly, and have not yet hit a hard limit. Previous studies argued that human life expectancy is increasing by ...
