内容：
We establish the ultimate quantum limits to the amplification of an unknown coherent state in the realistic setting where the expected photon number is finite. Moreover, we provide the benchmark that must be surpassed by experimental demonstrations in order to beat any classical amplification strategy and demonstrate genuine quantum amplification. Our results guarantee that a successful demonstration is in principle possible for every finite value of the expected photon number.
