Abstract: (arXiv)
If we want to transform the quantum of state of a system to another using local processes, what is the probability of success? It turns out that this probability can be bounded by quantifying entanglement within both the states. In this paper, we construct a family of multipartite entanglement measures that are monotonic under local operations and classical communication on average. The measures are constructed out of local unitary invariant polynomials of the state and its conjugate, and hence are easy to compute for pure states. Using these measures we bound the success probability of transforming a given state into another state using local quantum operations and classical communication.
