    "abstract": "We study the loss of entanglement of bipartite state subjected to discarding\nor measurement of one qubit. Examining the behavior of different entanglement\nmeasures, we find that entanglement of formation, entanglement cost, and\nlogarithmic negativity are lockable measures in that it can decrease\narbitrarily after measuring one qubit. We prove that any convex and\nasymptotically non-continuous measure is lockable. As a consequence, all the\nconvex roof measures can be locked. Relative entropy of entanglement is shown\nto be a non-lockable measure.",
