Summary

• What is new: Demonstration of a femtosecond biphoton source in nanophotonics with a bandwidth of 17 THz, centered at 2.09 μm, and a brightness of 8.8 GHz/mW.
• Why this is important: Scalable ultrafast quantum information processing (QIP) requires improvements in the sources of quantum states, particularly in their speed and integration into nanophotonic systems.
• What the research proposes: Development of a femtosecond biphoton source in dispersion-engineered periodically poled lithium niobate nanophotonics, achieving ultrafast operation suitable for scalable QIP.
• Results: Achieved a bandwidth of 17 THz, ultrafast operation, and a brightness of 8.8 GHz/mW, which are significant improvements towards scalable ultrafast QIP.
