Versatile relative entropy bounds for quantum networks
Luca Rigovacca, Go Kato, Stefan Bäuml +3
We provide a versatile upper bound on the number of maximally entangled qubits, or private bits, shared by two parties via a generic adaptive communication protocol over a quantum…
Secure Quantum Network Coding on Butterfly Network
Masaki Owari, Go Kato, Masahito Hayashi
Quantum network coding on the butterfly network has been studied as a typical example of quantum multiple cast network. We propose secure quantum network coding on the butterfly ne…
Information-theoretic security proof of differential-phase-shift quantum key distribution protocol based on complementarity
Akihiro Mizutani, Toshihiko Sasaki, Go Kato +2
We show the information-theoretic security proof of the differential-phase-shift (DPS) quantum key distribution (QKD) protocol based on the complementarity approach [arXiv:0704.366…
Differential-phase-shift quantum key distribution protocol with small number of random delays
Yuki Hatakeyama, Akihiro Mizutani, Go Kato +2
The differential-phase-shift (DPS) quantum key distribution (QKD) protocol was proposed aiming at simple implementation, but it can tolerate only a small disturbance in a quantum c…
