Optical Filter Cavity with 20 MHz FWHM(Los 1)+ Optical Filter Cavity with 38 MHz FWHM(Los 2) Fraunhofer IOF is developing advanced quantum optical resources to enable universal continuous-variable (CV) quantum computing. A fundamental result in CV quantum information is that Gaussian states and Gaussian operations alone are insufficient for universal quantum computation—non-Gaussian states are an essential ingredient to achieve computational universality. Photon subtraction from squeezed vacuum is a well-established technique to generate such non-Gaussian states (e.g., Schrödinger kitten states). However, single-mode squeezed states typically exhibit spectral correlations arising from the generation process, and if these correlations are not addressed, the photon subtraction acts incoherently across multiple spectral modes, severely degrading the purity and non-Gaussian character of the resulting state. Optical filter cavities provide precise spectral filtering to isolate a single, well-defined spectral mode, ensuring that the heralded photon subtraction operates coherently and produces high-fidelity non-Gaussian states. The acquisition of high-finesse optical filter cavities is therefore critical to prepare spectrally pure squeezed states compatible with photon number subtraction, enabling Fraunhofer IOF to generate the non-Gaussian resources required for universal CV quantum computing.
