    "abstract": "The usual entanglement swapping protocol can entangle two particles that\nnever interact. Here we demonstrate an all-versus-nothing violation of local\nrealism for a partial entanglement swapping process. A\nClauser-Horne-Shimony-Holt-type inequality for two particles entangled by\nentanglement swapping is proposed for a practical experiment and can be\nviolated quantum mechanically up to 4 beyond Cirel\u0027son\u0027s bound 2sqr(2). Our\nresult uncovers the intriguing nonlocal character of entanglement swapping and\nmay lead to a conclusive (loophole-free) test of local realism versus quantum\nmechanics. The experimental test of the nonlocality under current technology is\nalso discussed.",
