Abstract
We analyse the entanglement nature of quantum complementarity in individual and simultaneous continuous-variable (CV) quantum nondemolition measurements of coordinate and momentum. The complementarity expressed by the uncertainty relations is compared with an information-theoretical analysis of the quantum correlations. To demonstrate the entanglement nature, new CV quantum erasing experiments are suggested, employing only Gaussian states and feasible quantum optical devices, as parametrical processes, beamsplitters and homodyne detections.
