Optimal estimation of entanglement in optical qubit systems
G. Brida, I. P. Degiovanni, A. Florio +5
We address the experimental determination of entanglement for systems made of a pair of polarization qubits. We exploit quantum estimation theory to derive optimal estimators, whic…

Experimental estimation of entanglement at the quantum limit
Giorgio Brida, Ivo Degiovanni, Angela Florio +5
Entanglement is the central resource of quantum information processing and the precise characterization of entangled states is a crucial issue for the development of quantum techno…
