VANCOUVER, BC, April 16, 2026 /CNW/ - BTQ Technologies Corp. ("BTQ" or the "Company") (Nasdaq: BTQ) (CBOE CA: BTQ), a global quantum technology company focused on securing mission-critical networks, today highlighted new collaborative research led through the work of Chief Quantum Officer Dr. Gavin K. Brennen, advancing quantum error correction for permutation-invariant codes.
BTQ-Led Research Contribution with Macquarie University and University of Sheffield
The research, conducted as new work from BTQ and Macquarie University with Yingkai Ouyang at the University of Sheffield, reinforces BTQ's direct role in foundational quantum research. Dr. Brennen is a co-author of the paper alongside Dr. Ouyang, underscoring BTQ's active involvement in advancing core scientific frameworks that may support more resilient next-generation quantum systems.
What the Paper Introduces: A General Error-Correction Framework for Permutation-Invariant Codes
In the paper, A theory of quantum error correction for permutation-invariant codes, the authors present what they describe as the first general theory of error correction for permutation-invariant, or PI, codes. According to the abstract, the work introduces efficient algorithms that can correct any correctable error on any PI code, and also presents a simpler quantum error correction algorithm for certain erasure and deletion errors.
Advancing Reliability as Quantum Systems Scale
In simple terms, this research addresses one of the biggest obstacles in quantum computing: keeping quantum systems accurate and reliable as they scale. By advancing new methods for correcting errors more efficiently, BTQ is contributing to the foundational infrastructure required to move quantum technology from theory toward practical, real-world use. This reinforces BTQ's role in developing core intellectual property and technical expertise in areas expected to be critical to the long-term evolution of quantum computing and secure quantum systems. This significance is grounded in the paper's focus on quantum error correction, which is broadly considered a core requirement for robust quantum systems.
"This work reflects BTQ's commitment to advancing the foundational technologies that will underpin practical quantum systems," said Gavin Brennen, Chief Quantum Officer of BTQ Technologies. "By contributing directly to research in quantum error correction, BTQ is helping expand the theoretical tools needed to protect quantum information and improve the resilience of future quantum technologies. In the end, quantum machines will process information using codes that provide the best performance for a target application, be it storing quantum memory for communications, acquiring signals for quantum sensing, or fault tolerant quantum computing. We showed that PI codes, which are less well studied than stabilizer codes, are capable of correcting standard errors as well as errors that other codes can't, and at the same time are simpler to control in some architectures."
The paper marks a progression from the team's earlier work on PI codes for error-corrected quantum sensing and code switching for universal gates, highlighting BTQ's continued momentum in this research track.
Foundational R&D Supporting Secure Quantum Infrastructure
BTQ continues to advance commercialization across its quantum technology platform, pairing foundational research with product-focused execution. Through QPerfect, BTQ is progressing software and tooling designed to support the development and operation of next-generation quantum systems, including QLU - fault-tolerant quantum control software intended to bridge high-level quantum programs to error-corrected execution. By combining applied product development with ongoing innovation in core enabling layers such as quantum error correction, BTQ is focused on building durable, commercially relevant capabilities that support the long-term deployment of secure and scalable quantum technologies.
BTQ continues to support research and development across quantum and post-quantum technologies, with a focus on high-value technical domains that align with the Company's long-term strategy in secure computation, communications, and mission-critical infrastructure. By combining advanced research with commercialization-focused development across its broader platform, BTQ aims to build durable long-term value at the intersection of quantum innovation and security.
