Applied Quantum works with governments, defence communities and public institutions at the intersection of national security, critical infrastructure, industrial strategy and quantum sovereignty. We build sovereign quantum computing infrastructure from open‑architecture components, secure cryptographic systems for the quantum era, and help you understand where your quantum technology dependencies create strategic risk — turning that insight into coherent strategies, procurement frameworks and programmes you control.
Sector Overview
For governments and defence communities, quantum is a strategic asset, a systemic risk, and increasingly a sovereignty question. It touches intelligence, military communications, critical‑infrastructure protection, public‑sector digital services, industrial policy, national competitiveness — and the control of the technology supply chains that underpin all of these.
The difficulty is coordinating across:
- national‑level security concerns (state communications, archives, defence systems);
- sector‑specific regulation (finance, energy, telecoms, healthcare, transport);
- industrial and research ecosystems that are still emerging and fragmented;
- quantum technology supply chains where critical dependencies on foreign vendors, cloud platforms, and software stacks create strategic vulnerabilities.
We help national and defence stakeholders move from scattered briefings and pilot projects to coherent strategies that address quantum security, quantum capability, and quantum sovereignty together.
Who we work with
We support national and public sector stakeholders such as:
- Central government ministries/departments and digital/ICT authorities
- Defence and armed forces – including cyber, signals intelligence and secure comms units.
- National security and intelligence – long‑term data protection, secure comms and sensing.
- Critical‑infrastructure regulators – energy, transport, telecoms, water and other vital sectors.
- Law‑enforcement and homeland security agencies.
- Science, innovation and industrial‑strategy agencies / sovereign funds – national quantum ecosystems, industrial policy, sovereign quantum infrastructure, and investment screening for quantum technology.
Where quantum matters
Building sovereign quantum infrastructure
- Building quantum computers from open‑architecture modular components, delivered operational and under national control — with no single‑vendor lock‑in.
- Developing and deploying the OS and middleware layers that make multi‑vendor quantum platforms operational — under sovereign control, with auditable source code.
- Connecting quantum platforms to national HPC infrastructure and classified compute environments.
- Structuring national quantum procurement to support Quantum Open Architecture, multi‑vendor ecosystems, and sovereign optionality at every critical technology layer.
Sovereignty & supply chain resilience
- Mapping quantum technology dependencies across hardware, software, cloud access, standards, talent and investment — identifying where foreign concentration creates unacceptable risk.
- Running facilitated sovereignty stress tests: simulating supplier cutoffs, cloud revocations, standards bifurcation, export denials, and talent shocks to surface vulnerabilities before they are exploited.
- Designing investment screening criteria for quantum technology acquisitions, balancing beneficial foreign capital with protection of strategic capabilities.
- Coordinating national quantum programmes with allied nations — sharing roadmaps, aligning standards, and pooling supply chain optionality without creating new dependencies.
Defending against the quantum threat
- Building national‑level quantum‑security and PQC strategies covering multiple critical sectors.
- Setting regulatory expectations for PQC, crypto‑agility, CBOMs and long‑term confidentiality.
- Running enterprise‑scale PQC migration programmes across government and critical infrastructure.
- Assessing and securing quantum projects themselves — especially where they interact with classified or critical networks.
Quantum applications & national programmes
- Designing national and sectoral quantum strategies that combine research, industrial policy and adoption in defence and public services.
- Supporting pilots and testbeds in quantum sensing, secure communications, optimisation and computing.
- Developing workforce and skills programmes so civil servants, defence teams and regulators can make informed decisions.
- Running R&D programmes and collaborative projects that advance national quantum capability while building domestic expertise.

Relevant Case Studies
Quantum Sovereignty Assessment and Stress Test for a National Programme
We mapped a government's quantum technology dependencies across hardware, software, cloud, talent, and investment, then ran facilitated tabletop scenarios to stress‑test them. The work revealed hidden supply chain single points of failure, critical foreign software dependencies, and talent concentration risks — and led to new procurement policies requiring sovereignty impact assessments, QPU supply chain diversification toward open architecture, and commissioning of a sovereign middleware layer.
Sovereign Quantum Computing Procurement Strategy for a Government Ministry
A government ministry was preparing to procure its first quantum computer through a conventional RFP scoped around monolithic, vertically integrated systems. Our review identified vendor lock-in risks, sovereignty gaps, and a lack of internal capability to evaluate proposals rigorously. We recommended a structured pause to build hands-on experience through cloud quantum access, assess the full range of options including open-architecture builds, and redesign the procurement framework. The ministry is now preparing a refreshed RFI and RFP that will evaluate monolithic, modular, and hybrid approaches on equal footing — resulting in a better-informed decision on better terms.
Quantum Workforce and Skills Strategy for a National Programme
Aligning quantum talent strategy with national ambitions - We supported a national initiative in defining the workforce and skills dimension of its quantum strategy. This included mapping current talent supply across academia and industry, identifying critical gaps in security, engineering and commercialisation skills, and designing education, training and partnership programmes to build a sustainable quantum workforce.
