About Quantropi
Founded in Ottawa in 2018, Quantropi builds quantum-secure data communications. Its technology, quantum mechanics expressed as linear algebra, encrypts data in transit and at rest against today's threats and future quantum attacks, without needing the processing power of a quantum computer or any new hardware and infrastructure.
The QiSpace platform brings together three product families. MASQ provides post-quantum asymmetric encryption for key exchange and digital signatures, supporting NIST PQC alongside Quantropi's own algorithm with smaller signatures. QEEP is quantum-secure symmetric encryption, benchmarked at up to 18 times faster than AES-256. SEQUR delivers quantum random numbers and quantum-secure distribution over any existing network.
Quantropi is a 100 per cent Canadian company serving government, technology, finance and telecommunications, and a 2025 NATO DIANA Innovator. Its research is published in IEEE and Springer venues, QiSpace has been benchmarked by Deutsche Telekom in its OpenQKD lab, and it holds a Deloitte Technology Fast 50 award.
