Precision Light for Quantum Key Distribution

Stand E1301

14th May 2025

Quantum Key Distribution (QKD) relies on absolute stability – and Koheras lasers deliver. With ultra-narrow linewidths, low phase noise, and long coherence lengths, they provide the precision light sources needed for secure quantum communication. Whether used in phase-encoded or continuous-variable QKD systems, Koheras lasers ensure high-fidelity quantum state transmission over long distances.

Their telecom-band operation makes them ideal for use on existing fiber networks, and their compact, robust design supports OEM integration in both terrestrial and satellite-based QKD. In a field where security depends on signal integrity, Koheras lasers help make quantum encryption commercially viable and technically reliable.
