An Upper Bound to the Undetected Error Exponent with Erasure Decoding at Positive Rates
Seyed AmirPouya Moeini, Marco Dalai, Albert Guillén i Fàbregas
We study the undetected-error exponent of discrete memoryless channels with erasure decoding. Assuming that the undetected-error and erasure probabilities vanish, we derive an uppe…

The Expurgated Error Exponent is Not Universally Achievable
Seyed AmirPouya Moeini, Marco Dalai, Albert Guillén i Fàbregas
We study the universal attainability of the expurgated error exponent for discrete memoryless channels (DMCs). While the random-coding exponent is known to be universally attainabl…

Zero-Error List Decoding for Classical-Quantum Channels
Marco Dalai, Filippo Girardi, Ludovico Lami
The aim of this work is to study the zero-error capacity of pure-state classical-quantum channels in the setting of list decoding. We provide an achievability bound for list-size t…
