Key Points

Achieving synchronization of two Ti:Sapphire lasers reduces timing errors to around 3 picoseconds, enhancing photon indistinguishability.
Using the White Rabbit Precision Time Protocol ensures that the lasers operate effectively over a distance of 50 km, supporting future applications.
The method demonstrates a promising approach for generating indistinguishable photons crucial for advanced quantum technologies.
Key implications include potential improvements in quantum communication and quantum computing applications through better photon synchronization.

Implication

Experimental demonstration of synchronization of Ti:Sapphire lasers over 50 km, suggesting improvements for indistinguishable photons.

Abstract

We demonstrate picosecond-level synchronization (≈3 ps) of two actively mode-locked Ti:Sapphire lasers via the White Rabbit Precision Time Protocol across 50 km of optical fiber, meeting the requirements of pump lasers for indistinguishable single-photon sources.
