On Variational Expressions for Quantum Relative Entropies
Mario Berta, Omar Fawzi, Marco Tomamichel
Distance measures between quantum states like the trace distance and the fidelity can naturally be defined by optimizing a classical distance measure over all measurement statistic…
Algorithmic Aspects of Optimal Channel Coding
Siddharth Barman, Omar Fawzi
A central question in information theory is to determine the maximum success probability that can be achieved in sending a fixed number of messages over a noisy channel. This was f…
Quantum Bilinear Optimization
Mario Berta, Omar Fawzi, Volkher B. Scholz
We study optimization programs given by a bilinear form over non-commutative variables subject to linear inequalities. Problems of this form include the entangled value of two-prov…
Universal recovery map for approximate Markov chains
David Sutter, Omar Fawzi, Renato Renner
A central question in quantum information theory is to determine how well lost information can be reconstructed. Crucially, the corresponding recovery operation should perform well…
Analysis of classifiers' robustness to adversarial perturbations
Alhussein Fawzi, Omar Fawzi, Pascal Frossard
The goal of this paper is to analyze an intriguing phenomenon recently discovered in deep networks, namely their instability to adversarial perturbations (Szegedy et. al., 2014). W…
