Linear programs for entanglement and key distribution in the quantum internet
Stefan Bäuml, Koji Azuma, Go Kato +1
Quantum networks will allow to implement communication tasks beyond the reach of their classical counterparts. A pressing and necessary issue for the design of quantum network prot…
Simple security proof of twin-field type quantum key distribution protocol
Marcos Curty, Koji Azuma, Hoi-Kwong Lo
Twin-field (TF) quantum key distribution (QKD) was conjectured to beat the private capacity of a point-to-point QKD link by using single-photon interference in a central measuring…
Do black holes store negative entropy?
Koji Azuma, Sathyawageeswar Subramanian, Go Kato
The Bekenstein-Hawking equation states that black holes should have entropy proportional to their areas to make black hole physics compatible with the second law of thermodynamics.…
Quantum key distribution with setting-choice-independently correlated light sources
Akihiro Mizutani, Go Kato, Koji Azuma +6
Despite the enormous theoretical and experimental progress made so far in quantum key distribution (QKD), the security of most existing QKD implementations is not rigorously establ…
