Heisenberg’s uncertainty principle is, without any doubt, one of the most profound statements in modern quantum physics. Its widespread formulation in terms of standard deviations captures the essence of quantum mechanics and is a consequence of a very basic approach of this particular theory, namely to treat massive particles as travelling waves. However, Heisenberg’s original formulation is based on a description of an (underlying) measurement process. The reintroduction of this concept, generally referred to as error-disturbance uncertainty relations, has gained a lot of attention in recent years, both on theoretical and experimental sides. In this project we proceed with experimental studies of weak values, i.e., extended values of an observable depended on both a pre– and a post-selected state vector, as well as generalized error-disturbance uncertainty relations using neutron matter waves.
