Fault Tolerance of Random Graphs with respect to Connectivity: Mean-field Approximation for Semi-dense Random Graphs
Satoshi Takabe, Takafumi Nakano, Tadashi Wadayama
The fault tolerance of random graphs with unbounded degrees with respect to connectivity is investigated, which relates to the reliability of wireless sensor networks with unreliab…
On Zero Error Capacity of Nearest Neighbor Error Channels with Multilevel Alphabet
Takafumi Nakano, Tadashi Wadayama
This paper studies the zero error capacity of the Nearest Neighbor Error (NNE) channels with a multilevel alphabet. In the NNE channels, a transmitted symbol is a -tuple of elem…
Analysis of Breakdown Probability of Wireless Sensor Networks with Unreliable Relay Nodes
Takayuki Nozaki, Takafumi Nakano, Tadashi Wadayama
In the present paper, we derive an upper bound of the average network breakdown probability of packet networks with unreliable relay nodes. We here assume that relay nodes get inde…
Negativity of quantumness and its interpretations
Takafumi Nakano, Marco Piani, Gerardo Adesso
We analyze the general nonclassicality of correlations of a composite quantum systems as measured by the negativity of quantumness. The latter corresponds to the minimum entangleme…
