Estimates for the computational capacity of living systems generally assume that the fundamental information-processing unit is the Hodgkin-Huxley neuron, thereby excluding aneural organisms.\n\n\n\nfrom the conclusion:\n\"The proteins studied…form vast cytoskeletal architectures across almost all domains of carbon-based life, and they exhibit single-photon superradiance. That is, even in the limit of a single photon shared coherently across n quantum two-level systems, these protein architectures support superradiant states (with radiative decay rates nγ>Γj>γ for each state j) that are strongly coupled to the electromagnetic field due to their collective long-range interaction.\"",
