Realization schemes for quantum instruments in finite dimensions
Giulio Chiribella, Giacomo Mauro D'Ariano, Paolo Perinotti
We present a general dilation scheme for quantum instruments with continuous outcome space in finite dimensions, in terms of an indirect POVM measurement performed on a finite dime…
Optimal quantum tomography for states, measurements, and transformations
A. Bisio, G. Chiribella, G. M. D'Ariano +2
We present the first complete optimization of quantum tomography, for states, POVMs, and various classes of transformations, for arbitrary prior ensemble and arbitrary representati…
Transforming quantum operations: quantum supermaps
G. Chiribella, G. M. D'Ariano, P. Perinotti
We introduce the concept of quantum supermap, describing the most general transformation that maps an input quantum operation into an output quantum operation. Since quantum operat…
Optimal cloning of unitary transformations
G. Chiribella, G. M. D'Ariano, P. Perinotti
After proving a general no-cloning theorem for black boxes, we derive the optimal universal cloning of unitary transformations, from one to two copies. The optimal cloner is realiz…
