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…
LOCC protocols for entanglement transformations
G. M. D'Ariano, M. F. Sacchi
We construct the protocols to achieve probabilistic and deterministic entanglement transformations for bipartite pure states by means of local operations and classical communicatio…
The quantum bit commitment: a complete classification of protocols
Giacomo Mauro D'Ariano
This paper addresses the controversy between Mayers, Lo and Chau on one side, and Yuen on the opposite side, on whether there exist or not unconditionally secure protocols. For suc…
The quantum bit commitment: a finite open system approach for a complete classification of protocols
Giacomo Mauro D'Ariano
Mayers, Lo and Chau argued that all quantum bit commitment protocols are insecure, because there is no way to prevent an Einstein-Podolsky-Rosen (EPR) cheating attack. However, Yue…
On the Heisenberg principle, namely on the information-disturbance trade-off in a quantum measurement
Giacomo Mauro D'Ariano
Common misconceptions on the Heisenberg principle are reviewed, and the original spirit of the principle is reestablished in terms of the trade-off between information retrieved by…
The Quantum Monty Hall Problem
G. M. D'Ariano, R. D. Gill, M. Keyl +3
We consider a quantum version of a well-known statistical decision problem, whose solution is, at first sight, counter-intuitive to many. In the quantum version a continuum of poss…
