Mixed Quantum Communications
Secure infrastructure for Earth and orbit.
We build satellite infrastructure as one system, quantum security, optical communication, on-board compute and geospatial intelligence, so satellite data can travel securely, be understood sooner and become a decision without waiting for everything to reach the ground.

The problem
Satellite networks were not designed for the amount, or the sensitivity, of the data they now carry.
01
The link is the bottleneck
Sensors outgrew downlinks. Radio-frequency links are spectrum-constrained and congested, so the majority of what a satellite captures is discarded, downsampled or delayed before it ever reaches an analyst.
02
Security is an afterthought
Most links inherit classical encryption designed for a threat model that predates large-scale quantum computing. Encrypted traffic captured today can be stored and decrypted later, which makes today's key material tomorrow's exposure.
03
Decisions wait for the ground
Raw data travels down, gets processed, then travels back as an answer. For a flood, a fire or an unfolding change on the ground, the answer arrives after the moment it mattered.
Our thesis
Security, bandwidth, compute and interpretation designed as one system.
- Quantum-native security
- Security runs through the architecture from the entropy source up.
- Optical as the connectivity layer
- Optical links are the path to the bandwidth these payloads need, and they carry a narrow beam that is far harder to intercept than a broadcast.
- Intelligence at the edge
- Process where the data is created. Move only the answer.
- One system, end to end
- Each layer is useful on its own and worth more when combined. That is how we sequence the company.
Product demo
What we're building.
Quantum entropy source
A physical process whose measurement outcomes are fundamentally unpredictable.
Digitization
The analogue signal is sampled into raw bits while the source's bias and correlation are characterized.
Randomness extraction
Post-processing that converts a biased physical signal into a uniform output stream.
Continuous health testing
Online tests run against the raw source and stop output when a device degrades.
Key material
A uniform stream available to the systems that consume it, over a documented interface.
A flow diagram: a quantum entropy source feeds a digitizer, then randomness extraction and continuous health tests, producing a random bit stream used as cryptographic key material by a secure system.

Why now
Four curves crossed at the same time.
This company would not have been buildable five years ago, and the window is not indefinite.
01
Cryptography is being replaced, once
NIST published the first post-quantum standards, FIPS 203, 204 and 205, on 13 August 2024. Every operator of long-lived infrastructure is now planning a key-management migration. Systems being specified today will still be flying in the 2040s.

02
Recorded traffic is a future liability
An adversary who stores encrypted traffic now can decrypt it once the capability exists. For satellite links carrying government, energy or financial data, weak key material turns stored traffic into a future liability.
03
Sensors outgrew downlinks
Constellation counts and per-satellite sensor resolution keep rising while the radio spectrum available to move that data does not. This structural gap makes both optical links and on-board processing necessary.
04
Inference finally fits on a payload
Modern low-power accelerators put useful models inside a CubeSat power budget. Processing on board stopped being a research exercise and became an engineering choice.
