Efficient single-spatial-mode PPKTP waveguide source for high dimensional entanglement-based QKD

Efficient single-spatial-mode PPKTP waveguide source for high dimensional entanglement-based QKD

8.9×10 8 /s single-spatial-mode time-energy entangled photon pairs at 1.56 μm are efficiently generated in a PPKTP waveguide, demonstrating Mbps key rates and 93.3% Franson quantum-interference visibility using high speed self-differencing InGaAs detectors.
