Divergences in QED on a Graph
Nahomi Kan, Kiyoshi Shiraishi
We consider a model of quantum electrodynamics (QED) on a graph. The one-loop divergences in the model are investigated by use of the background field method.
A precise estimation of the computational complexity in Shor's factoring algorithm
K. Kuriyama, S. Sano, S. Furuichi
A precise estimation of the computational complexity in Shor's factoring algorithm under the condition that the large integer we want to factorize is composed by the product of two…
Generalized Shannon inequalities based on Tsallis relative operator entropy
Kenjiro Yanagi, Ken Kuriyama, Shigeru Furuichi
Tsallis relative operator entropy is defined and then its properties are given. Shannon inequality and its reverse one in Hilbert space operators derived by T.Furuta \cite{Fu:par}…
Fundamental properties of Tsallis relative entropy
S. Furuichi, K. Yanagi, K. Kuriyama
Fundamental properties for the Tsallis relative entropy in both classical and quantum systems are studied. As one of our main results, we give the parametric extension of the trace…
One-loop effective potential for the vacuum gauge field in space-times
Yoshinori Cho, Kiyoshi Shiraishi
We calculate the effective potential for the vacuum gauge field from the one-loop matter effect in space-time. This background geometry is motivated from…
On trace inequalities and their applications to noncommutative communication theory
Kenjiro Yanagi, Shigeru Furuichi, Ken Kuriyama
Certain trace inequalities related to matrix logarithm are shown. These results enable us to give a partial answer of the open problem conjectured by A.S.Holevo. That is, concavity…
