Why Now

The clock to Q-Day is already running.

The world's digital ecosystem is under rising attack. Enterprises must become quantum-resilient before the day today's encryption breaks.

Q-Day

When quantum computers break today's RSA encryption

RSA → 0

Today's public-key crypto becomes obsolete overnight

What is Q-Day?

Q-Day is the moment a quantum computer can break the RSA encryption protecting today's data and communications. Harvested encrypted data can be decrypted retroactively — so resilience must come first.

02 / Technology

Keys generated in orbit. Delivered as a service.

Satellite distribution overcomes the range limits of terrestrial fiber optics — extending quantum-secure keys anywhere on Earth.

Step 01 · In Orbit

Integrated-photonics QKD chip

A compact integrated-photonics chip onboard each satellite generates and transmits quantum keys from space using quantum entanglement.

Step 02 · On the Ground

Key Management System (KMS)

A software platform delivers QKD-as-a-Service — securely managing, distributing, and integrating quantum keys into enterprise systems.

Advantages

Why quantum keys from space win.

Global coverage

LEO satellite constellation delivers quantum keys anywhere on Earth.
Compact & scalable

An integrated-photonics QKD chip small enough to scale across a constellation.
QKD-as-a-Service

A software platform (KMS) delivers quantum keys on demand to enterprises.
Quantum-attack proof

Keys remain secure even against the quantum computers of Q-Day.
Eavesdropping detection

Physics guarantees tamper-evidence — any interception is detectable.
