Efficient use of quantum resources for the transmission of a reference frame
G. Chiribella, G. M. D'Ariano, P. Perinotti +1
We propose a covariant protocol for transmitting reference frames encoded on spins, achieving sensitivity without the need of a pre-established reference frame and wit…

Covariant quantum measurements which maximize the likelihood
Giulio Chiribella, Giacomo Mauro D'Ariano, Paolo Perinotti +1
We derive the class of covariant measurements which are optimal according to the maximum likelihood criterion. The optimization problem is fully resolved in the case of pure input…
