Sometimes it is possible in quantum theory for a system to interact with another system in such a way that the information contained in the wave function becomes very scrambled and apparently incoherent. We produce an example which is exactly calculable, in which a macroscopic change is induced in the environment, and all phase information for the system is apparently lost, so that a measurement has seemingly been made. But actually, although the wave function has been badly scrambled, all the original information is still present. We call this situation one of latent order.Subsequently, the system interacts again with the environment, wiping out the macroscopic change, and the wave function once again becomes manifestly coherent. Thus the apparent measurement has been undone, and leaves no aftereffect. Thus, our measurement has disappeared without a trace. We call such a measurement a haunted measurement, and we believe that until the measurement process is rigorously understood, the concept of measurement is ambiguous. It is just not good enough to say that an amplification stage occurs somewhere in the process.We also point out the connection between the haunted measurement and delayed-choice experiments and discuss a haunted version of the Schrödinger's Cat experiment and of the Einstein-Podolsky-Rosen experiment. 相似文献
