Abstract
Nearly all of the measurements that detect individual events taking place at the quantum level depend in one way or another on a process of amplification. That amplification process, though essential to detection, may also impose certain limits on what can be detected. We shall discuss briefly some of the elements necessary to build a quantum amplifier and some of the features of the way in which such an amplifier works. We then discuss the application of these ideas to some experiments that show how the amplification process influences what is detected. One corollary, we shall see, is that no linear amplification process can lead to any such paradox as “Schrödinger’s cat”.
