Bell Violation with Discrete-Continuous Entanglement
We describe a new Bell test for two-party entangled systems, one that engages an unbounded continuous variable. The continuous variable state is allowed to be arbitrary and inaccessible to direct measurements. A systematic method is introduced to perform the required measurements indirectly. Our results provide a new perspective both in the study of local realistic theory for continuous variable systems and in the nonlocal control theory of quantum information.
