Quantum calibration of measuring apparatuses
Giacomo Mauro D'Ariano, Lorenzo Maccone, Paoloplacido Lo Presti
By quantum calibration we name an experimental procedure apt to completely characterize an unknown measurement apparatus by comparing it with other calibrated apparatuses. Here we…
Classical randomness in quantum measurements
Giacomo Mauro D'Ariano, Paoloplacido Lo Presti, Paolo Perinotti
Similarly to quantum states, also quantum measurements can be "mixed", corresponding to a random choice within an ensemble of measuring apparatuses. Such mixing is equivalent to a…
About the use of entanglement in the optical implementation of quantum information processing
M. G. A. Paris, G. M. D'Ariano, P. Lo Presti +1
We review some applications of entanglement to improve quantum measurements and communication, with the main focus on the optical implementation of quantum information processing.…
Improved discrimination of unitaries by entangled probes
G. Mauro D'Ariano, Paoloplacido Lo Presti, Matteo G. A. Paris
We consider the problem of discriminating among a set of unitaries by means of measurements performed on the state undergoing the transformation. We show that use of entangled prob…
A quantum measurement of the spin direction
G. M. D'Ariano, P. Lo Presti, M. F. Sacchi
We give a first physical model for the quantum measurement of the spin direction. It is an Arthurs-Kelly model that involves a kind of magnetic-dipole interaction of the spin with…
Optimal Non-Universally Covariant Cloning
G. M. D'Ariano, P. Lo Presti
We consider non-universal cloning maps, namely cloning transformations which are covariant under a proper subgroup G of the universal unitary group U(d), where d is the dimension o…
