Summary

Story summary

The fiber-laser-based computing architecture for quantum computing (fs CIM) uses 1555-nm mode-locked fiber laser to produce ~100-fs pulses with >100 mW output.
A second harmonic generation stage and a PPLN crystal enable efficient operation.
The system achieves 2.5 times higher second-harmonic-generation (SHG) efficiency than picosecond lasers and gains stability from a new cavity stabilization system.
Stabilization reduces temperature fluctuations and allows the fs CIM to operate for over 8 hours.
