Description:
Author(s): Tommaso Macrì, Augusto Smerzi, and Luca Pezzè We propose a versatile Loschmidt echo protocol to detect and quantify multiparticle entanglement. It allows us to extract the quantum Fisher information for arbitrary pure states, and finds direct application in quantum metrology. In particular, the protocol applies to states that are generally diff… [Phys. Rev. A 94, 010102(R)] Published Wed Jul 06, 2016
