Telescopic Relative Entropy--II Triangle inequalities
Koenraad M. R. Audenaert
In previous work (see arxiv:1102.3040), we have defined the telescopic relative entropy (TRE), which is a regularisation of the quantum relative entropy $S(ρ||σ)=\traceρ(\logρ-\log…

Telescopic Relative Entropy
Koenraad M. R. Audenaert
We introduce the telescopic relative entropy (TRE), which is a new regularisation of the relative entropy related to smoothing, to overcome the problem that the relative entropy be…
