Investigation of the silicon vacancy color center for quantum key distribution

Memory-Assisted Quantum Key Distribution with a Single Nitrogen-Vacancy Center

Silicon Single Photon Avalanche Diodes for Quantum Key Distribution

The progress in silicon planar device technologies has led single-photon avalanche diodes (SPAD) to emerge from the laboratory research phase and be commercially available from various manufactures. QKD systems can already exploit the available planar Si-SPAD devices, but they set strong demand for improved features and performance. A response can be given by new developments in a dedicated sil...

Multiphoton-Excited Fluorescence of Silicon-Vacancy Color Centers in Diamond

Silicon-vacancy color centers in nanodiamonds are promising as fluorescent labels for biological applications, with a narrow, nonbleaching emission line at 738 nm. Two-photon excitation of this fluorescence offers the possibility of low-background detection at significant tissue depth with high threedimensional spatial resolution. We measure the two-photon fluorescence cross section of a negati...

Quantum key distribution relied on trusted information center

Quantum correlation between two particles and among three particles show nonclassic properties that can be used for providing secure transmission of information. In this paper, we propose two quantum key distribution schemes for quantum cryptographic network, which use the correlation properties of two and three particles. One is implemented by the Greenberger-Horne-Zeilinger state, and another...
