## Abstract We study the role of entanglement in the transmission of classical information over noisy quantum channels. We show that entanglement leads to an enhancement of the mutual information when the transmission channel is not memoryless.

## 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
