    "abstract": "Two observers (Alice and Bob) independently prepare two sets of singlets.\nThey test one particle of each singlet along an arbitrarily chosen direction\nand send the other particle to a third observer, Eve. At a later time, Eve\nperforms joint tests on pairs of particles (one from Alice and one from Bob).\nAccording to Eve\u0027s choice of test and to her results, Alice and Bob can sort\ninto subsets the samples that they have already tested, and they can verify\nthat each subset behaves as if it consisted of entangled pairs of distant\nparticles, that have never communicated in the past, even indirectly via other\nparticles.",
