Complete condition for nonzero quantum correlation in continuous variable systems
Quantum correlation provides a promising measure beyond entanglement. Here, we propose a necessary and sufficient condition for nonzero quantum correlation in continuous variable systems, which is simple and easy to perform in terms of a marker Q _r . In order to get this condition, we introduce con...
