WebbAmong Shannon's results for specific channels, the most celebrated is that for a power-limited continuous-amplitude channel subject to white Gaussian noise. If the signal power is limited to PS and the noise power is PN, the capacity of such a … WebbShannon's noisy coding theorem says that for a memoryless channel, C = sup p X I ( X; Y), where p X is maximized over all probability distributions over the input variable X. If you try to apply this naïvely to quantum channels, you run into a bunch of problems:
