Disturbance, conservation laws and the uncertainty principle

Hans Martens, Willem M. de Muynck

Abstract

The interpretation of the uncertainty principle in terms of a measurement of a single observable disturbing other observables, originating in Heisenberg's 1927 paper, is shown to be derivable from an uncertainty principle for joint measurements of incompatible observables. The latter also limits measurements of a single observable in the presence of conservation laws.
