Upconversion single photon detection near 2 um
Guo-Liang Shentu, Xiu-Xiu Xia, Qi-Chao Sun +4
We have demonstrated upconversion detection at the single photon level in the 2 um spectral window using a pump wavelength near 1550nm, a periodically poled lithium niobate (PPLN)…
217 km long distance photon-counting optical time-domain reflectometry based on ultra-low noise up-conversion single photon detector
Guo-Liang Shentu, Qi-Chao Sun, Xiao Jiang +5
We demonstrate a photon-counting optical time-domain reflectometry with 42.19 dB dynamic range using an ultra-low noise up-conversion single photon detector. By employing the long…
Experimental unconditionally secure bit commitment
Yang Liu, Yuan Cao, Marcos Curty +13
Bit commitment is a fundamental cryptographic task that guarantees a secure commitment between two mutually mistrustful parties and is a building block for many cryptographic primi…
Ultralow noise up-conversion detector and spectrometer at telecom band
Guo-Liang Shentu, Jason S. Pelc, Xiao-Dong Wang +5
We demonstrate upconversion single-photon detection for the 1550-nm band using a PPLN waveguide, long-wavelength pump, and narrowband filtering using a volume Bragg grating. We ach…
