## Abstract A novel scheme to realize the whole class of quantum nondemolition (QND) measurements of a field quadrature is suggested. The setup requires linear optical components and squeezers, and allows optimal QND measurements of quadratures, which minimize the information gain versus state dist

It is shown that, to obtain higher sensitivity in quantum experiments with test masses, an oscillator is more promising than a free mass. New methods of realization of mechanical rigidity with very low quantum noise are described. Possible schemes of quantum measurements based of these method are di
Gravity-induced quantum interference is a remarkable effect that has already been confirmed experimentally, and it is a phenomenon in which quantum mechanics and gravity play simultaneously an important role. Additionally, a generalized version of this interference experiment could offer the possibi
