On contraction coefficients, partial orders and approximation of capacities for quantum channels
Christoph Hirche, Cambyse Rouzé, Daniel Stilck França
The data processing inequality is the most basic requirement for any meaningful measure of information. It essentially states that distinguishability measures between states decrea…
Energy-constrained discrimination of unitaries, quantum speed limits and a Gaussian Solovay-Kitaev theorem
Simon Becker, Nilanjana Datta, Ludovico Lami +1
We investigate the energy-constrained (EC) diamond norm distance between unitary channels acting on possibly infinite-dimensional quantum systems, and establish a number of results…
Approximate tensorization of the relative entropy for noncommuting conditional expectations
Ivan Bardet, Angela Capel, Cambyse Rouzé
In this paper, we derive a new generalisation of the strong subadditivity of the entropy to the setting of general conditional expectations onto arbitrary finite-dimensional von Ne…
