BTQ TECHNOLOGIES COMPLETES ACQUISITION OF QPERFECT, ADVANCING ITS MISSION OF BUILDING TRUSTED QUANTUM TECHNOLOGIES WITH WORLD-CLASS EMULATION, DIGITAL TWIN, AND CONTROL CAPABILITIES

BTQ Technologies Corp. has completed the acquisition of QPerfect SA, a French quantum computing company based in Strasbourg specializing in quantum software, emulation, digital twin capabilities and control systems.

The completion of the acquisition follows BTQ's previously announced strategic investment in QPerfect and exercise of its option to acquire the remaining outstanding securities of the company. For further details on the acquisition see the company's previously disseminated news release dated July 1, 2026, filed on SEDAR+ and EDGAR. Following the closing, QPerfect is now a wholly owned subsidiary of BTQ.

QPerfect is led by a team of scientists and engineers who have spent years advancing the frontier of neutral atom physics, quantum optics, quantum software engineering and quantum system design. Founded in 2023, the company is recognized with the i-Lab Grand Prix and is known for breakthrough work in quantum emulation, bringing world-class quantum software, emulation, digital twin and control capabilities for neutral atom platforms. QPerfect's technologies are designed to help researchers, developers, and hardware manufacturers model, test, benchmark, and control quantum systems before and during deployment on quantum hardware.

Strategic rationale

The acquisition strengthens BTQ's ability to build technologies for the transition from classical infrastructure toward trusted quantum systems. For BTQ, "Building Trusted Quantum Technologies" means preparing modern network infrastructure to securely co-exist with quantum computers. This is achieved by protecting modern systems from quantum-enabled threats, helping future networks remain secure, verifiable and trusted throughout the quantum transition.

As organizations begin preparing for postqantum cryptography, complexities surrounding efficiency and implementation are becoming critical challenges for adoption. Quantum-safe cryptography can introduce larger keys, heavier computational requirements, more complex handshakes, and new constraints for embedded systems, telecommunications infrastructure, defence environments and other performance-sensitive networks. BTQ believes the transition will require not only new cryptographic standards, but also optimized hardware, software, simulation and control layers that make quantum-secure systems practical to deploy at scale.

By integrating QPerfect's technology and team, BTQ adds three important capabilities to its expanding quantum-ready infrastructure stack:

• Mimiq, QPerfect's benchmark-leading quantum emulator, which enables developers and researchers to design, test, and validate quantum algorithms in software before deploying them on quantum hardware. Designed to outperform existing simulators and current quantum computers in targeted benchmark environments, Mimiq has demonstrated stable 100-plus qubit simulations on standard computing infrastructure, helping lower the barrier to large-scale quantum algorithm development, validation and security testing.
• Digital Twin, QPerfect's system modeling capability, which is designed to create software-based representations of quantum systems, helping researchers and hardware developers simulate, optimize, and better understand quantum architectures and performance before physical deployment.
• Quantum Logical Unit, or QLU, QPerfect's multilayered control framework designed to support the development of scalable, fault-tolerant quantum systems.

Together, these capabilities are expected to support practical validation and testing frameworks for quantum-ready infrastructure, including next-generation TLS handshakes, PQC migration validation, quantum-safe secure communications, protocol resilience, interoperability testing and hybrid quantum-classical network environments. These use cases are particularly relevant for defence, telecommunications, critical infrastructure, and other sectors where secure communications must be tested, validated and hardened before deployment.

"Completing the acquisition of QPerfect is an important milestone for BTQ," said Olivier Roussy Newton, chief executive officer and chairman of BTQ. "QPerfect brings world-class quantum software, emulation, digital twin and neutral atom expertise into our organization. These capabilities expand our technology stack and advance our mission of building trusted quantum technologies by helping organizations prepare for the software, modelling, validation and control layers required for future quantum systems."

"We built QPerfect to solve one of the hardest problems in quantum computing -- making quantum systems testable, reproducible and deployable at scale," said Philippe Blot, chief executive officer of QPerfect. "BTQ shares that ambition, and brings the global infrastructure and security focus to help us go further, faster. This partnership with BTQ comes at the right time for quantum technology and aligns perfectly with the long-standing collaboration between France and Canada, recently strengthened by the joint statement on quantum sciences and technologies signed on May 29, 2026, on the sidelines of the French-presided Digital G7. We are particularly pleased to continue developing QPerfect in France, on the campus of the European Center for Quantum Sciences (CESQ)."

QPerfect's Strasbourg hub anchors BTQ's European R&D (research and development)

Through the acquisition, BTQ will further anchor its European quantum research and development activities in Strasbourg, France, within a growing academic, scientific and industrial quantum ecosystem.

QPerfect's location and network provide BTQ with access to specialized talent, research partnerships and technical expertise across quantum simulation, control systems, neutral atom computing and quantum design automation. The company expects this European presence to support continuing collaboration with universities, research institutions and industrial partners as BTQ continues to develop deployable trusted quantum technologies.

Research, grants and in-house expertise

QPerfect has established strong research relationships across the European Union quantum ecosystem, including collaborations with universities, research institutions and industrial partners in quantum computing. These relationships provide QPerfect with access to specialized expertise across quantum simulation, neutral atom computing, quantum design automation and control systems, while supporting continued development of technologies for scalable quantum systems.

QPerfect's in-house expertise is also reflected in recent research aligned with its emulation, Digital Twin and QLU road map:

• Noise tailoring for error mitigation and diagnosing digital quantum computers:
  • This paper introduces noise tailoring, a method designed to modify the structure of two-qubit gate noise through statistical sampling. In classical emulation, the authors report that noise tailoring combined with error mitigation can be up to five times more accurate than error mitigation alone for realistic Pauli noise, while also proposing the method as a diagnostic tool for hardware development.
• Correlated atom loss as a resource for quantum error correction:
  • This paper is directly relevant to neutral-atom architectures and QPerfect's work in QLU and Digital Twin modelling. It introduces a decoder that exploits correlated atom-loss structures in neutral-atom quantum processors, reporting up to an order-of-magnitude reduction in logical error probability and an increase in the loss threshold from 3.2 per cent to 4 per cent.

Together, these grants, publications, and research activities reinforce QPerfect's role as a research-driven quantum software company advancing the simulation, validation and control layers needed for scalable neutral-atom quantum systems.
