There is no classical analog of a quantum time-translation machine
Lev Vaidman A
In a recent article [D. Suter, Phys. Rev. A 51, 45 (1995)] Suter has claimed to present an optical implementation of the quantum time-translation machine that ``shows all the features that the general concept predicts and also allows, besides the quantum-mechanical, a classical description.'' It is argued that the experiment proposed and performed by Suter does not have the features of the quantum time-translation machine and that the latter has no classical analog.
