Four For 21: Quantum Companies Founded in The Year of The Ox

Making a Mark

In the last piece in this series, The Quantum Insider covered two exciting companies founded in the year 2022, the Chinese Year of the Tiger. This time, stepping back another twelve months, we go to 2021 where we discover four more companies making their own, unique mark in the quantum computing (QC) industry.

If you want to learn more, we’ve compiled the most comprehensive list of the top quantum computing companies available!

Made possible by the depth of information readily available on our proprietary data platform, look out for more insightful posts in this vein and others in the growing QC sector.

1. Aquabits


A University of Waterloo spinoff, backed by the world-class research taking place at the Mike and Ophelia Lazaridis Quantum-Nano Centre and Research and Development Centre, Aquabits is creating disruptive technology for quantum computing and quantum information processing through a novel scalable multi-qubit Trapped Ion Platform.

4. Patero

Finally, we come to Patero, a startup setting a new security standard for critical infrastructure in our rapidly changing post-quantum world.

Founded by Henning Schiel and based in College Park, Maryland, operators and builders of critical OT networks use Patero’s technology to secure their communications infrastructure against the most sophisticated cyber-attacks, even Quantum Computing powered attacks.

Patero’s innovative Hybrid Post-Quantum Cryptographic (H-PQC) software has been specifically developed for easy deployment into existing IT, OT, IoT, and Mobile systems, providing uncompromisable end-to-end security, even across unsecured networks. The hybrid approach combines the best of both classic cryptography and post-quantum cryptography to maximize defence and ensure network performance.
