A relative version of this quantity may be computed for two discrete distributions and is also called the Kullback-Leibler divergence. A quantum extension of this quantity may be computed by the negative trace of the product of the density matrix with its natural logarithm, named for Von Neumann. The expected value of a certain random variable gives the (*) Shannon kind of this quantity, useful to information theory. The Gibbs paradox is a statement about its discontinuity, and it is expected to approach zero as a system approaches absolute zer
