Paper Abstract

Several examples for preparations of quantum states and of quantum measurements are presented. The analysis of these procedures have shown that the minimal error of the energy ΔE may be limited in some cases by γ/τ, (where τis the time of preparation or measurement) or may be significantly smaller in other cases. The possibilities to observe the existence of the shortest natural time interval τplanck approximately equals 10-43s are discussed. One of the possible ways to observe this phenomenon is based on the decoherence measurement of the macroscopic test mass which is well isolated from the heat bath and optimally coupled with Quantum Non Demolition meter.
