A Spectrum-Based Converse for Quantum State Discrimination and Its Applications to Classical-Quantum Channel Coding
Tam{á}s Havas, Hsuan-Yin Lin, Eirik Rosnes
We investigate converse bounds on the average decoding error probability in finite-blocklength classical-quantum channel coding. We first present a lower bound for multiple quantum…

On Finite-Blocklength Noisy Classical-Quantum Channel Coding With Amplitude Damping Errors
Tamás Havas, Hsuan-Yin Lin, Eirik Rosnes +1
We investigate practical finite-blocklength classical-quantum channel coding over the quantum amplitude damping channel (ADC), aiming to transmit classical information reliably thr…
