Over the last two decades, photonic quantum technologies have reached several significant milestones. However, scalability remains a major challenge when translating lab results into everyday applications. Applications frequently necessitate using over 1,000 optical components, each of which must be individually optimized.
On the other hand, photonic quantum technologies can benefit from parallel advances in classical photonic integration. The integrated photonic platforms, which require a wide range of materials, component designs, and integration strategies, present several challenges, particularly signal losses, which are difficult to compensate for in the quantum world.
The complex innovation cycle for integrated photonic quantum technologies (IPQT) necessitates investments, the resolution of specific technological challenges, the development of necessary infrastructure, and additional structuring toward a mature ecosystem. Scientists and engineers with extensive knowledge of quantum mechanics and its technological applications are in high demand.
