Quantum security

Quantum computers will eventually break the encryption we rely on today.

However, as quantum computing advances, so does its potential to protect sensitive data.

QMill is building a new paradigm for quantum-safe security, powered by quantum computing itself.

Quantum-powered cryptography:
An extra layer of security

Secure communication relies on two steps: exchanging a secret key, then using that key to protect the actual communication. QMill strengthens both.

◾ Verified randomness: Every cryptographic key depends on random numbers, but that randomness is rarely verifiable. QMill's algorithms generate verified random numbers using the inherent randomness of quantum mechanics and verifies them using light classical computing. The result is randomness that is both quantum grade and easy to audit without any assumptions on the physical device that generated the results.

◾Quantum-powered key establishment: Post-quantum algorithms are a major step forward, but they are new, and the current key encapsulation schemes rest on a small number of closely related mathematical problems. QMill has built a key establishment mechanism that is based on a fundamentally different problem and quantum computing to establish the keys. It can run standalone or in concert with other post-quantum cryptographic primitives, guaranteeing an additional layer of protection built for security-critical use cases.

BUILT AND TESTED WITH INDUSTRY PARTNERS

QMill's solutions are ready to use with present-day quantum hardware, and will fully mature as quantum computers begin to realize their full potential towards the end of this decade.

Together with Telia, we developed quantum-powered message encryption for mobile networks and showcased it to the Finnish Defence Forces over a live network.

Our approach fits the industry's shift toward crypto-agility: building systems that can add or swap in stronger cryptographic modules as new threats and standards emerge, rather than treating migration as a one-time fix.

Why it matters now

The capabilities of quantum computers are rapidly evolving, and are projected to culminate in the so-called Q-Day, when their computational power will be sufficient to break today’s encryption methods.

Q-Day is projected to occur within a decade, but many forecasts believe it could happen before 2030. Meanwhile, sensitive encrypted data is already being collected and stored, a practice known as ‘harvest now, decrypt later’, ready to be unlocked once that day comes.

Many national and institutional bodies are therefore now recommending a full transition to quantum-safe cryptography by the end of the decade. New quantum-safe standards are already being rolled out, but they rely on the hardness of a certain type of classical-computing task. QMill adds the missing layer: security based on the hardness of quantum computing for classical devices and the loss of information in the collapse of the quantum state during its measurement, without the need for a dedicated quantum communication infrastructure.
