Security of quantum key distribution with iterative sifting
Kiyoshi Tamaki, Hoi-Kwong Lo, Akihiro Mizutani +4
Several quantum key distribution (QKD) protocols employ iterative sifting. After each quantum transmission round, Alice and Bob disclose part of their setting information (includin…
Fundamental limitation on quantum broadcast networks
Stefan Bäuml, Koji Azuma
The ability to distribute entanglement over complex quantum networks is an important step towards a quantum internet. Recently, there has been significant theoretical effort, mainl…
Aggregating quantum repeaters for the quantum internet
Koji Azuma, Go Kato
The quantum internet holds promise for performing quantum communication, such as quantum teleportation and quantum key distribution, freely between any parties all over the globe.…
Fundamental rate-loss tradeoff for the quantum internet
Koji Azuma, Akihiro Mizutani, Hoi-Kwong Lo
The quantum internet holds promise for performing quantum communication, such as quantum teleportation and quantum key distribution (QKD), freely between any parties all over the g…
