  • Where P(Alpha) Is A Gaussian Distribution Of Finite Variance And |Alpha &Gt
  • Is A Coherent State
  • Can Be Better Discriminated With An Entangled Measurement Than With Any Local Strategy Supplemented
  • Although This Ensemble Consists Of Products Of Quasiclassical States Without Any Squeezing
  • It Thus Exhibits A Purely Quantum Feature
  • This Remarkable Effect Is Demonstrated Experimentally By Implementing The Optimal Local Strategy On
