[en] Quantum Key distribution (QKD) is a cryptographic information transmission method that relies on quantum properties of photons to transmit information securely. Two methods are regarded as promising to generate single-photons (consisting of a signal and an idler), namely Four-Wave Mixing (FWM), and Spontaneous Parametric Down-Conversion (SPDC). Here, we present a heralded source of single-photons generated due to degenerate FWM in an experimental Photonic Crystal Fibre (PCF).
