Entanglement Theory and the Second Law of Thermodynamics
... To demonstrate reversibility of entanglement manipulation under the class just introduced we define two quantities and prove that they are the same. The entanglement cost under asymptotically nonentangling maps EC (ρ) is defined as the infimum of limn→∞ knn over all the sequences of quantum maps {Ψn ...

The singularity in GR is radically different from field theory singularities because it is a property not of some field but of the space-time itself.
