Quantum Broadcast Channel Simulation via Multipartite Convex Splitting
Hao-Chung Cheng, Li Gao, Mario Berta
We show that the communication cost of quantum broadcast channel simulation under free entanglement assistance between the sender and the receivers is asymptotically characterized…

Sphere-Packing Bound for Symmetric Classical-Quantum Channels
Hao-Chung Cheng, Min-Hsiu Hsieh, Marco Tomamichel
We provide a sphere-packing lower bound for the optimal error probability in finite blocklengths when coding over a symmetric classical-quantum channel. Our result shows that the p…
