Rigorous calibration method for photon-number statistics
Masahiro Kumazawa, Toshihiko Sasaki, Masato Koashi
Characterization of photon statistics of a light source is one of the most basic tools in quantum optics. Although the outcome from existing methods is believed to be a good approx…
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…
A security proof of the round-robin differential phase shift quantum key distribution protocol based on the signal disturbance
Toshihiko Sasaki, Masato Koashi
The round-robin differential phase shift (RRDPS) quantum key distribution (QKD) protocol is a unique quantum key distribution protocol whose security has not been understood throug…
Finite-key analysis for quantum key distribution with weak coherent pulses based on Bernoulli sampling
Shun Kawakami, Toshihiko Sasaki, Masato Koashi
An essential step in quantum key distribution is the estimation of parameters related to the leaked amount of information, which is usually done by sampling of the communication da…
