ABSTRACT: This paper presents photonic communications and data
storage capacitates for classical and quantum communications over a quantum
channel. These capacities represent a generalization of Shannon’s classical
channel capacity and coding theorem in two ways. First, it extends classical
results for bit communication transport to all frequencies in the electromagnetic
spectrum. Second, it extends the results to quantum bit (qubit) transport as
well as a hybrid of classical and quantum communications. Nature’s limits on
the rate at which classical and/or quantum information can be sent error-free
over a quantum channel using classical and/or quantum error-correcting codes
are presented as a function of the thermal background light level and Einstein
zero-point energy. Graphical results are given as well as numerical results
regarding communication rate limits using Planck’s natural frequency and
time-interval units!
