    "abstract": "We present an alternative definition of quantum entanglement for bipartite\nsystem based on Bell inequality and operators\u0027 noncommutativity. A state is\nsaid to be entangled, if the maximum of CHSH expectation value $F_{\\max}$ is\nobtain by noncommutative measures on each particle of the bipartite system;\notherwise, the state is a disentangled state. A uniform measure quantifying the\ndegree of entanglement for any state of the bipartite system is also proposed.",
