    "abstract": "We propose a method for directly probing the dynamics of disentanglement of\nan initial two-qubit entangled state, under the action of a reservoir. We show\nthat it is possible to detect disentanglement, for experimentally realizable\nexamples of decaying systems, through the measurement of a single observable,\nwhich is invariant throughout the decay. The systems under consideration may\nlead to either finite-time or asymptotic disentanglement. A general\nprescription for measuring this observable, which yields an operational meaning\nto entanglement measures, is proposed, and exemplified for cavity quantum\nelectrodynamics and trapped ions.",
