Quantum Conditional Mutual Information, Reconstructed States, and State Redistribution
Fernando G. S. L. Brandao, Aram W. Harrow, Jonathan Oppenheim +1
We give two strengthenings of an inequality for the quantum conditional mutual information of a tripartite quantum state recently proved by Fawzi and Renner, connecting it with the…
Unbounded number of channel uses are required to see quantum capacity
Toby Cubitt, David Elkouss, William Matthews +3
Transmitting data reliably over noisy communication channels is one of the most important applications of information theory, and well understood when the channel is accurately mod…
Game-theoretic characterization of antidegradable channels
Francesco Buscemi, Nilanjana Datta, Sergii Strelchuk
We introduce a guessing game involving a quantum channel, three parties - the sender, the receiver and an eavesdropper, Eve - and a quantum public side channel. We prove that a nec…
