An operational measure for squeezing
Martin Idel, Daniel Lercher, Michael M. Wolf
We propose and analyse a mathematical measure for the amount of squeezing contained in a continuous variable quantum state. We show that the proposed measure operationally quantifi…
Standard super-activation for Gaussian channels requires squeezing
Daniel Lercher, Géza Giedke, Michael M. Wolf
The quantum capacity of bosonic Gaussian quantum channels can be non-additive in a particularly striking way: a pair of such optical-fiber type channels can individually have zero…
Tsirelson's bound from a Generalised Data Processing Inequality
Oscar C. O. Dahlsten, Daniel Lercher, Renato Renner
The strength of quantum correlations is bounded from above by Tsirelson's bound. We establish a connection between this bound and the fact that correlations between two systems can…
