Abstract :
Quantum Gaussian channels play an important role in quantum optical communication systems. For these channels, we calculate the Gallager functions which enable us to evaluate the speed of exponential decay of the minimal error probability at different rates. Among other quantum continuous channels, the Gaussian channel can be handled analytically due to its simple correlation structure
