Tight finite-key security for twin-field quantum key distribution
Guillermo Currás-Lorenzo, Alvaro Navarrete, Koji Azuma +3
Quantum key distribution (QKD) offers a reliable solution to communication problems that require long-term data security. For its widespread use, however, the rate and reach of QKD…
Quantum key distribution with correlated sources
Margarida Pereira, Go Kato, Akihiro Mizutani +2
In theory, quantum key distribution (QKD) offers information-theoretic security. In practice, however, it does not due to the discrepancies between the assumptions used in the secu…
Enumeration of associative magic squares of order 7
Go Kato, Shin-ichi Minato
An associative magic square is a magic square such that the sum of any 2 cells at symmetric positions with respect to the center is constant. The total number of associative magic…
A Tight Bound of Tail Probabilities for a Discrete-time Martingale with Uniformly Bounded Jumps
Go Kato
We investigate the properties of a discrete-time martingale , where all differences between adjacent random variables are limited to be not more…
