Quorum of observables for universal quantum estimation
G. Mauro D'Ariano, Lorenzo Maccone, Matteo G. A. Paris
Any method for estimating the ensemble average of arbitrary operator (observables or not, including the density matrix) relates the quantity of interest to a complete set of observ…
Orthogonality relations in Quantum Tomography
G. M. D'Ariano, L. Maccone, M. G. A. Paris
Quantum estimation of the operators of a system is investigated by analyzing its Liouville space of operators. In this way it is possible to easily derive some general characteriza…
Optical Fock-state synthesizer
G. M. D'Ariano, L. Maccone, M. G. A. Paris +1
We suggest a tunable optical device to synthesize Fock states and their superpositions starting from a coherent source. The scheme involves an avalanche triggering photodetector an…
