Quantum contextuality in N-boson systems
F. Benatti, R. Floreanini, M. Genovese +1
Quantum contextuality in systems of identical bosonic particles is explicitly exhibited via the maximum violation of a suitable inequality of Clauser-Horne-Shimony-Holt type. Unlik…
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…
Statistical estimation of the quality of quantum-tomography protocols
Yu. I. Bogdanov, G. Brida, I. D. Bukeev +6
We present a complete methodology for testing the performances of quantum tomography protocols. The theory is validated by several numerical examples and by the comparison with exp…
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…
