Quantum Open Architecture (QOA): The “PC Moment” of Quantum Computing
Today, a sea change is underway. Quantum Open Architecture (QOA) is doing for quantum computing what the PC revolution did for classical computing - opening up the ecosystem. Just as the computing world shifted from monolithic mainframes to modular PCs…

Quantum Sovereignty in Practice: When Geopolitics Becomes Architecture
At its core, quantum sovereignty means having full control over the critical layers of quantum technology domestically - the ability to design, manufacture, and operate quantum systems without external dependency. In practice, this implies a country could build a complete…

How the EU Can Capture the Benefits of Quantum Computing
The European Union has entered the global quantum race with determination - aiming not just to excel in research, but to translate breakthroughs into economic and strategic benefits. In July 2025, the European Commission unveiled the Quantum Europe Strategy, a…

Sovereignty Stress Tests: Tabletop Scenarios for States and Enterprises
In an era of quantum and digital sovereignty, governments and companies must ensure they aren’t caught off-guard by geopolitical tech disruptions. Building on my previous analyses of quantum sovereignty and a number of Applied Quantum client engagements, I wanted to…

Investment Screening and M&A: When Capital Becomes a Quantum Sovereignty Vector
Foreign investment screening, acquisition scrutiny, and “strategic capital” policies increasingly shape which quantum technology companies survive - and where their intellectual property (IP) and talent ultimately reside. National security and technological sovereignty narratives are no longer abstract concerns; they influence…

Quantum Sovereign Optionality: Agility Over Autarky
Technical sovereignty has become a buzzword in geopolitical and tech circles. As global alliances fray and trust in traditional partners wanes, countries are scrambling to assert control over critical technologies. In the quantum arena, this instinct translates into an ambitious…

Sovereign Quantum Clouds and National Control
Quantum computing is rapidly shifting from lab prototypes to cloud-based services. Most organizations will access quantum capabilities “as a service” through cloud platforms, rather than owning a quantum computer on-premise. This shift reframes the sovereignty debate. The question is no…

Quantum Systems Integration
Quantum Systems Integration (QSI) refers to the holistic process of designing, assembling, and deploying quantum computing systems and ensuring they work seamlessly with classical systems. In simpler terms, a quantum systems integrator is like a general contractor for quantum projects…

Chokepoints and Industrial Base Realism: What “Quantum Supply Chain Sovereignty” Actually Means
Talk of quantum sovereignty - a nation’s independent control over quantum technology - means little unless backed by tangible supply chain control. Quantum innovation relies on narrow, specialized supply chains that are globally dispersed and often fragile. Major powers have…

Sovereignty in the PQC Era: Standards, Trust, and Crypto-Agility
Post-Quantum Cryptography (PQC) is entering the standards stage, with the U.S. National Institute of Standards and Technology (NIST) recently selecting the first quantum-resistant algorithms. However, the future of PQC will not be as straightforward as simply adopting NIST’s choices globally.…

The Border Around Quantum: Export Controls, Deemed Exports, and “Research as a Controlled Flow”
Export controls have emerged as a main lever to throttle or channel the flow of quantum know-how and equipment, effectively drawing new borders through the global R&D ecosystem. Quantum sovereignty, in other words, isn’t just about spending more on R&D;…

Quantum Tech and Espionage: What Every Researcher Must Know
To the untrained eye, espionage against scientists can be nearly invisible - it blends into everyday academic or business activity. But certain red flags and tactics surface again and again. Below is a consolidated list of common espionage methods (many…

Alliances as “Sovereignty Multipliers”
Turning strategic alignment into real technological capability requires deliberate mechanisms at the alliance level. Formal statements of partnership (like NATO communiqués or bilateral MOUs) only matter if backed by concrete programs and standards. So let's outline key ways alliances can…

Quantum Human Capital Controls as Geopolitics
Quantum sovereignty is talent-constrained. In the race for quantum technology leadership, a skilled workforce has become a strategic asset - and a policy battleground. Nations are increasingly treating talent as a key lever of geopolitics, shaping immigration visas, research-security screening,…

Physics at the Heart of the New Cold War
In the 21st century, cutting-edge physics has moved from the laboratory into the realm of high geopolitics. Breakthroughs in quantum computing, advanced materials, and energy aren’t just academic - they are strategic assets coveted by nations. The situation echoes the…
