Quantum Reference Frames, Time and Measurements
Abstract
We argue that correct account of the quantum properties of macroscopic objects which form reference frames (RF) demand the change of the standard spacetime picture accepted in Quantum Mechanics. The presence of RF free quantum motion in the form of wave packet smearing results in formal nonapplicability of Galilean or Lorentz spacetime transformations in this case. For the description of the particles states transformations between different quantum RF the special quantum spacetime transformations are formulated. Consequently it results in corrections to Schrodinger or Klein Gordon equations which depends on the RF mass. RF proper time becomes the operator depending of momentums spread in RF wave packet ,from the point of view of other observer. The experiments with macroscopic coherent states are proposed in which this effects can be tested.}
