@Joachim, thanks for the papers, I was going to write about zero-point energy as a strong argument for the uncertainty principle and how it is related to this precise measurement idea, but these papers have changed that.

Actually uncertainty principle is not about inaccuracy in measurement but it is about representing a system as a probabilistic set of states, where measurements of 2 complimentary observables (not the co-varying observables) do not commute when done is opposite chronology. It  means to say that if first momentum is observed and then position the set of measurements in not the same as if first position is measure and then the momentum. PX is not equal to XP.

An act of observation realizes one of the states of many states. So the uncertainty is not in the measurement but the underlying nature of the universe. As pointed above, it is actually possible to design experiment in a way that one can measure the most probable state with more accuracy than the h/2PI. It is still the measurement of the most probable state and NOT "THE STATE". If it was just a problem of measurement and not the underlying property of nature, one cannot see quantum tunneling as used in tunneling semi-conductor devices, which uses non-most probable states to operate. 

I have written some papers on matter light duality, realizing faster than light motion using existing equipment, problem with classical energy at:
