Abstract:
Quantum nonlocality characterizes a kind of important quantum correlations like quantum entanglement. We investigate the distribution of quantum nonlocality between two distant particles that were originally in a separable state. Similar to that separable states can be used to distribute entanglement [Phys. Rev. Lett. 91, 037902 (2003)], we show that it is also possible to establish the nonlocality between two distant particles by sending a third ancilla.
