Solid-state-based quantum communication and metrology are currently among the fastest-growing research areas in physics. They hold the promise of exciting fundamental science and simultaneously enabling transformative industrial applications, ranging from quantum-mechanically secure information encryption and quantum sensing using single-photon emitters and higher-order photonic states, to advanced quantum information processing in photonic frame-works and the certified distribution of complex states.
