The performance of communication through a quantum conductor is limited by the laws of physics. The optimum channel capacity, the maximum rate at which information can be transmitted under a given signal power, i.e., the heat current, connects the theory of communication, quantum physics, and thermodynamics. Here, the author calculates the distribution of fluctuations of self-information and finds a Jarzynski equality like universal relation connecting the fluctuations of information, the R\'enyi entropy of order zero, and the optimum capacity.
