1 Fig. 1 Photonic implementation of a fractional QKT.
Photonic implementation of a fractional QKT. (A) HOM interference of photon number states on a variable BS, followed by two photon-counting detectors, (B) Setup: Ti:Sa, titanium-sapphire laser pump (blue); BS, 50:50 BS; τ, optical phase delay; SPDC, periodically poled potassium titanyl phosphate nonlinear spontaneous parametric down-conversion waveguide chip that produces photon number–correlated states (red); VC, variable coupler; DAQ, data acquisition unit.
