    "abstract": "We consider the capacity of classical information transfer for noiseless\nquantum channels carrying a finite average number of massive bosons and\nfermions. The maximum capacity is attained by transferring the Fock states\ngenerated from the grand-canonical ensemble. Interestingly, the channel\ncapacity for a Bose gas indicates the onset of a Bose-Einstein condensation, by\nchanging its qualitative behavior at the criticality, while for a channel\ncarrying weakly attractive fermions, it exhibits the signatures of\nBardeen-Cooper-Schrieffer transition. We also show that for noninteracting\nparticles, fermions are better carriers of information than bosons.",
