Q FLUX
Quantum Key Distribution over classical optical networks — without dark fiber. Q FLUX multiplexes quantum signals with live data using CWDM, so you can deploy quantum‑grade key exchange on real infrastructure.
Form factor
1U rack / line‑card
Power
< 40 W (Fiber)
Distance
Up to 80 km (metro)
Space link
LEO 500–1,200 km

Deploy
Drop‑in at the fiber front end
Secure
Information‑theoretic key exchange
Scale
Works alongside live classical traffic
Two configurations.
Choose Q FLUX Fiber for terrestrial networks, or Q FLUX Space for ground‑to‑satellite key transmission.
Q FLUX Fiber
CV‑QKD for fiber networks
Drop‑in quantum security for data centers, metro networks, and backbone fiber — co‑propagating quantum keys alongside live classical traffic.
Q FLUX Space
BB84 transmitter for free‑space
Quantum key transmission beyond fiber — optimized for ground‑to‑LEO experiments and space‑ready programs.

| Feature | Q FLUX Fiber | Q FLUX Space |
|---|---|---|
| QKD type | CV‑QKD | DV‑QKD |
| Protocol | Gaussian‑modulated coherent states | BB84 (with decoy states) |
| Where it fits | Data centers & fiber networks | Ground‑to‑LEO links |
