When and how does entanglement end?

    Suppose two particles become entangled. Are they ever dis-entangled? If so, how? If not, wow.

    Thanks!

    When one of the pair (say Alice) is observed, it is no longer entangled on that basis (say spin or momentum). Bob will thereafter be observed to be consistent with Alice's result.
