Nonlocality swapping
Li‐Yi Hsu · Physical Review A · 2002
We propose a measurement scheme of generalized Bell states in which, although entanglement is destroyed, the nonlocality feature can be preserved and swapped. Here we consider two quantum systems: one consisting of two-party three-level maximal entangled pairs; the other being three-party two-level maximal entangled pairs. It is found that these local immeasurable states can be prepared without any classical communication and local operation. Moreover, nonmaximal entangled states cannot preserve nonlocality.
