Channel coding against quantum jammers via minimax
Michael X. Cao, Yongsheng Yao, Mario Berta
We introduce a minimax approach for characterizing the capacities of fully quantum arbitrarily varying channels (FQAVCs) under different shared resource models. In contrast to prev…

Quantum channel discrimination against jammers
Kun Fang, Michael X. Cao
We study the problem of quantum channel discrimination between two channels with an adversary input party (a.k.a. a jammer). This setup interpolates between the best-case channel d…

Exponents for Shared Randomness-Assisted Channel Simulation
Aadil Oufkir, Michael X. Cao, Hao-Chung Cheng +1
We determine the exact error and strong converse exponents of shared randomness-assisted channel simulation in worst case total-variation distance. Namely, we find that these expon…
