Résumé :

The fundamental limits on position measurements, which originated from quantum mechanics and classical general relativity, were described. Any primitive probe or target to be used in an experiment must be larger than the Planck length l P. The interferometers were also investigated, whose precision was much finer than the size of any individual components and were not limited by the minimum ball. The fundamental limit was also deduced for such interferometers on their accuracy of order l P. The results show a 'device independent' limit on possible measurements of position.
