Interaction modulation in a long-lived Bose-Einstein condensate by rf coupling
Kosuke Shibata, Aki Torii, Hitoshi Shibayama +3
We demonstrate modulation of the effective interaction between the magnetic sublevels of the hyperfine spin in a Rb Bose-Einstein condensate by Rabi coupling with radi…
Secret key rate of a continuous-variable quantum-key-distribution scheme when the detection process is inaccessible to eavesdroppers
Ryo Namiki, Akira Kitagawa, Takuya Hirano
We have developed a method to calculate a secret key rate of a continuous-variable quantum-key-distribution scheme using four coherent states and postselection for a general model…
Coexistence of Continuous Variable Quantum Key Distribution and 7 12.5 Gbit/s Classical Channels
Tobias A. Eriksson, Takuya Hirano, Motoharu Ono +6
We study coexistence of CV-QKD and 7 classical 12.5 Gbit/s on-off keying channels in WDM transmission over the C-band. We demonstrate key generation with a distilled secret key rat…
Dissipation-assisted coherence formation in a spinor quantum gas
Yujiro Eto, Hitoshi Shibayama, Kosuke Shibata +4
Dissipation affects all real-world physical systems and often induces energy or particle loss, limiting the efficiency of processes. Dissipation can also lead to the formation of d…
