Monotonicity of the Rényi channel capacity under non-signaling assisted channel simulation
Tina Shariat, Matt Hoogsteder-Riera, Marco Tomamichel
We give an alternative variational proof that non-signaling correlations shared between the sender and receiver cannot increase the Rényi capacity of a classical channel. This mono…

Approach to optimal quantum transport via states over time
Matt Hoogsteder-Riera, John Calsamiglia, Andreas Winter
We approach the problem of constructing a quantum analogue of the immensely fruitful classical transport cost theory of Monge from a new angle. Going back to the original motivatio…
