Metrological Detection of Multipartite Entanglement from Young Diagrams
Zhihong Ren, Weidong Li, Augusto Smerzi +1
We characterize metrologically useful multipartite entanglement by representing partitions with Young diagrams. We derive entanglement witnesses that are sensitive to the shape of…
Frequentist and Bayesian Quantum Phase Estimation
Yan Li, Luca Pezzè, Manuel Gessner +2
Frequentist and Bayesian phase estimation strategies lead to conceptually different results on the state of knowledge about the true value of the phase shift. We compare the two fr…
Characterizing the multipartite continuous-variable entanglement structure from squeezing coefficients and the Fisher information
Zhongzhong Qin, Manuel Gessner, Zhihong Ren +6
Understanding the distribution of quantum entanglement over many parties is a fundamental challenge of quantum physics and is of practical relevance for several applications in the…
