Quantum Conditional Mutual Information, Reconstructed States, and State Redistribution

Quantum Conditional Mutual Information, Reconstructed States, and State Redistribution

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 ability to reconstruct the state from its bipartite reductions. Namely, we show that the conditional mutual information...
