Erasing Distinguishability Using Quantum Frequency Up-Conversion
Hiroki Takesue
The frequency distinguishability of two single photons was successfully erased using single photon frequency up-conversion. A frequency non-degenerate photon pair generated via spo…
Megabits secure key rate quantum key distribution
Q. Zhang, H. Takesue, T. Honjo +10
Quantum cryptography (QC) can provide unconditional secure communication between two authorized parties based on the basic principles of quantum mechanics. However, imperfect pract…
Unconditional Security of Single-Photon Differential Phase Shift Quantum Key Distribution
Kai Wen, Kiyoshi Tamaki, Yoshihisa Yamamoto
In this Letter, we prove the unconditional security of single-photon differential phase shift quantum key distribution (DPS-QKD) protocol, based on the conversion to an equivalent…
Quantum Theory of Transmission Line Resonator-Assisted Cooling of a Micromechanical Resonator
Yong Li, Ying-Dan Wang, Fei Xue +1
We propose a quantum description of the cooling of a micromechanical flexural oscillator by a one-dimensional transmission line resonator via a force that resembles cavity radiatio…
Effect of detector dead-times on the security evaluation of differential-phase-shift quantum key distribution against sequential attacks
Marcos Curty, Kiyoshi Tamaki, Tobias Moroder
We investigate limitations imposed by detector dead-times on the performance of sequential attacks against a differential-phase-shift (DPS) quantum key distribution (QKD) protocol…
Security proof for QKD systems with threshold detectors
Toyohiro Tsurumaru, Kiyoshi Tamaki
In this paper, we rigorously prove the intuition that in security proofs for BB84 one may regard an incoming signal to Bob as a qubit state. From this result, it follows that all s…
