    "abstract": "The state of a quantum system, consisting of two distinct subsystems, is\ncalled separable if it can be prepared by two distant experimenters who receive\ninstructions from a common source, via classical communication channels. A\nnecessary condition is derived and is shown to be more sensitive than Bell\u0027s\ninequality for detecting quantum inseparability. Moreover, collective tests of\nBell\u0027s inequality (namely, tests that involve several composite systems\nsimultaneously) may sometimes lead to a violation of Bell\u0027s inequality, even if\nthe latter is satisfied when each composite system is tested separately.",
