Experimental realization of Counterfactual Quantum Cryptography
Giorgio Brida, Andrea Cavanna, Ivo Pietro Degiovanni +2
In counterfactual QKD information is transfered, in a secure way, between Alice and Bob even when no particle carrying the information is in fact transmitted between them. In this…
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…
Quantum characterization of superconducting photon counters
Giorgio Brida, Luigi Ciavarella, Ivo P. Degiovanni +7
We address the quantum characterization of photon counters based on transition-edge sensors (TESs) and present the first experimental tomography of the positive operator-valued mea…
