    "abstract": "We compare disentanglement and decoherence rates within two-spin and\nthree-spin entangled systems subjected to all possible combinations of local\nand collective pure dephasing noise combinations. In all cases, the bipartite\nentanglement decay rate is found to be greater than or equal to the\ndephasing-decoherence rates and often significantly greater. This sharpens\nprevious results for two-spin systems [T. Yu and J. H. Eberly Phys. Rev. B 68,\n165322 (2003)] and extends them to the three-spin context.",
