Quantum Sphere-Packing Bounds with Polynomial Prefactors
Hao-Chung Cheng, Min-Hsiu Hsieh, Marco Tomamichel
We study lower bounds on the optimal error probability in classical coding over classical-quantum channels at rates below the capacity, commonly termed quantum sphere-packing bound…
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…
Moderate Deviation Analysis for Classical-Quantum Channels and Quantum Hypothesis Testing
Hao-Chung Cheng, Min-Hsiu Hsieh
In this work, we study the tradeoffs between the error probabilities of classical-quantum channels and the blocklength when the transmission rates approach the channel capacity…
