Abstract
We analyze continuous-variable (CV) quantum duality induced by entanglement between the system and the meter in two feasible CV back-action evading measurements and suggest a CV analog of the quantum erasing, previously observed in the atomic interference experiments. The suggested experiments employ only the standard quantum optical devices, such as beam splitters, parametric oscillators, and homodyne detectors.
