Interstellar Communication. VIII. Hard limits on the number of bits per photon

(Submitted on 18 Jan 2018)

A photon can encode several bits of information based on an alphabet of its time of arrival, energy, and polarization. Heisenberg’s uncertainty principle places a limit on measuring pairs of physical properties of a particle, limiting the maximal information efficiency to <59 bits per photon in practice, and <171 bits per photon at Planck energy, at a data rate of one photon per second.
