Spontaneous parametric down-conversion (SPDC) – the splitting of a single photon in two – is crucial for photonic quantum technologies. In its very essence, SPDC breaks the inversion symmetry. It is therefore only possible in non-centrosymmetric crystals but not in isotropic materials like ordinary liquids or gases. Recently, however, ferroelectric nematic liquid crystals have been […]Spontaneous parametric down-conversion (SPDC) – the splitting of a single photon in two – is crucial for photonic quantum technologies.
