A Construction of Dynamical Entropy on CAR Algebras
Kyouhei Ohmura, Noboru Watanabe
The dynamical entropy on von Neumann algebras defined by Accardi, Ohya and Watanabe (AOW entropy) is a natural noncommutative extension of the classical dynamical entropy. On the o…
On Transmission Efficiency of Quantum Modulations
K. Ohmura, N. Watanabe
In quantum information theory, it is important to find modulations with low information loss for noisy channels. In this paper, using the quantum dynamical entropy and the quantum…
A Formulation of Rényi Entropy on -Algebras
Farrukh Mukhamedov, Kyouhei Ohmura, Noboru Watanabe
The entropy of probability distribution defined by Shannon has several extensions. Rényi entropy is one of the general extensions of Shannon entropy and is widely used in engineeri…
Double blinding-attack on entanglement-based quantum key distribution protocols
Guillaume Adenier, Irina Basieva, Andrei Yu. Khrennikov +2
We propose a double blinding-attack on entangled-based quantum key distribution protocols. The principle of the attack is the same as in existing blinding attack except that instea…
Multiple-Photon Absorption Attack on Entanglement-Based Quantum Key Distribution Protocols
Guillaume Adenier, Irina Basieva, Andrei Yu. Khrennikov +2
In elaborating on the multiple-photon absorption attack on Ekert protocol proposed in arXiv:1011.4740, we show that it can be used in other entanglement-based protocols, in particu…
Violation of Bell Inequalities with a Mixture of Separable States in a Multiple-Photon Absorption Attack on Ekert Protocol
Guillaume Adenier, Noboru Watanabe, Andrei Khrennikov +1
We propose a new type of attack on Ekert protocol in which, rather surprisingly, Eve drives a violation of Bell inequalities in Alice's and Bob's detectors with a mixture of separa…
