Journal ArticleDOI
Titanium-based transition-edge photon number resolving detector with 98% detection efficiency with index-matched small-gap fiber coupling
Daiji Fukuda,Go Fujii,Takayuki Numata,Kuniaki Amemiya,Akio Yoshizawa,Hidemi Tsuchida,Hidetoshi Fujino,Hiroyuki Ishii,Taro Itatani,Shuichiro Inoue,Tatsuya Zama +10 more
TL;DR: The overall system detection efficiency is 98%±1% at wavelengths of around 850 nm, which is the highest value ever reported in this wavelength range.
Journal ArticleDOI
800 MHz single-photon detection at 1550-nm using an InGaAs/InP avalanche photodiode operated with a sine wave gating.
TL;DR: Single-photon detection at 1550-nm with a high repetition rate was realized using an InGaAs/InP avalanche photodiode operated with a sine wave gating and the avalanche signal which is much smaller than that in the conventional gating results in the suppression of the afterpulsing.
Journal ArticleDOI
1.5 GHz single-photon detection at telecommunication wavelengths using sinusoidally gated InGaAs/InP avalanche photodiode.
TL;DR: A telecom-band single-photon detector for gigahertz clocked quantum key distribution systems based on a sinusoidally gated InGaAs/InP avalanche photodiode with quantum efficiency of 10.8 % is reported.
Journal ArticleDOI
Quantum receiver beyond the standard quantum limit of coherent optical communication.
Kenji Tsujino,Daiji Fukuda,Go Fujii,Go Fujii,Shuichiro Inoue,Mikio Fujiwara,Masahiro Takeoka,Masahide Sasaki +7 more
TL;DR: This work implements a quantum receiver with a simple linear optics configuration and achieves more than 90% of the total detection efficiency of the system, demonstrating the first unconditional evidence surpassing the standard quantum limit of coherent optical communication.
Journal ArticleDOI
Non-Gaussian operation based on photon subtraction using a photon-number-resolving detector at a telecommunications wavelength
Naoto Namekata,Yuta Takahashi,Yuta Takahashi,Go Fujii,Go Fujii,Daiji Fukuda,Sunao Kurimura,Shuichiro Inoue +7 more
TL;DR: In this paper, the authors implemented non-Gaussian operation in pulsed squeezed vacuum at a telecommunications wavelength using a titanium superconducting transition-edge sensor to resolve the incident photon number.
