Security analysis of decoy state quantum key distribution incorporating finite statistics
Jun Hasegawa, Masahito Hayashi, Tohya Hiroshima +1
Decoy state method quantum key distribution (QKD) is one of the promising practical solutions to BB84 QKD with coherent light pulses. In the real world, however, statistical fluctu…
Experimental Decoy State Quantum Key Distribution with Unconditional Security Incorporating Finite Statistics
Jun Hasegawa, Masahito Hayashi, Tohya Hiroshima +2
We propose the improved decoy state quantum key distribution incorporating finite statistics due to the finite code length and report on its demonstration. In our experiment, four…
A quantum protocol to win the graph colouring game on all Hadamard graphs
David Avis, Jun Hasegawa, Yosuke Kikuchi +1
This paper deals with graph colouring games, an example of pseudo-telepathy, in which two provers can convince a verifier that a graph is -colourable where is less than…
Theoretical Analyses of Quantum Counting against Decoherence Errors
Jun Hasegawa, Fumitaka Yura
In this paper, we analyze the quantum counting under the decoherence, which can find the number of solutions satisfying a given oracle. We investigate probability distributions rel…
