Programmable quantum channels and measurements
Giacomo Mauro D'Ariano, Paolo Perinotti
We review some partial results for two strictly related problems. The first problem consists in finding the optimal joint unitary transformation on system and ancilla which is the…
On the most efficient unitary transformation for programming quantum channels
Giacomo Mauro D'Ariano, Paolo Perinotti
We address the problem of finding the optimal joint unitary transformation on system + ancilla which is the most efficient in programming any desired channel on the system by chang…
Clean Positive Operator Valued Measures
F. Buscemi, G. M. D'Ariano, M. Keyl +2
In quantum mechanics the statistics of the outcomes of a measuring apparatus is described by a positive operator valued measure (POVM). A quantum channel transforms POVM's into POV…
Optimization of quantum universal detectors
G. M. D'Ariano, P. Perinotti, M. F. Sacchi
The expectation value <O> of an arbitrary operator O can be obtained via a universal measuring apparatus that is independent of O, by changing only the data-processing of the outco…
Secure communication using coherent states
Geraldo A. Barbosa, Eric Corndorf, Prem Kumar +4
We demonstrate that secure communication using coherent states is possible. The optimal eavesdropping strategy for an M-ry ciphering scheme shows that the minimum probability of er…
