    "abstract": "We consider whether quantum coherence in the form of mutual entanglement\nbetween a pair of qubits is susceptible to decay that may be more rapid than\nthe decay of the coherence of either qubit individually. An instance of\npotential importance for solid state quantum computing arises if embedded\nqubits (spins, quantum dots, Cooper pair boxes, etc.) are exposed to global and\nlocal noise at the same time. Here we allow separate phase-noisy channels to\naffect local and non-local measures of system coherence. We find that the time\nfor decay of the qubit entanglement can be significantly shorter than the time\nfor local dephasing of the individual qubits.",
