Information-Spectrum General Formulas for the Capacity Region of Classical-Quantum Multiple Access Channels
arXiv:2611.07462v1 Announce Type: new Abstract: For classical-quantum multiple access channels (cq-MACs) with two senders, we give several general expressions for the capacity region, valid for arbitrary sequences of channels. In the case of asymptotically vanishing error ($\varepsilon=0$), the capacity region is expressed in terms of spectral inf-mutual information rates. For every $0\le\varepsilon
