For the case of continuous variable systems we propose a possible experimental violation of this inequality, by using squeezed light and homodyne detection together with methods of quantum-state reconstruction. It is shown that the violation is also possible for realistic detection efficiencies.4 pages, 2 figuresQuantum Physicstext
