Applied Quantum supports operators of grids, plants, transport systems and industrial networks where safety, resilience and uptime are non negotiable. We help you understand how quantum technologies affect your OT/ICS, IT and supply chains – and where quantum sensing, optimisation or simulation can genuinely improve operations.
Sector Overview
Critical‑infrastructure and industrial operators sit where physical systems, OT/ICS, IT and national‑level risk meet. Their environments are complex, safety‑critical and often regulated – and were rarely designed with strong, agile cryptography in mind.
As grids, plants, networks and logistics chains become more connected and data‑rich, quantum becomes relevant in two ways:
- as a risk to long‑lived control systems, telemetry and operational data;
- as a tool for sensing, optimisation and simulation to enhance safety, reliability and efficiency.
Who we work with
We support operators across:
- Power generation, transmission and distribution.
- Oil, gas and petrochemical production, pipelines and trading.
- Water, wastewater and environmental‑infrastructure operations.
- Transportation networks.
- Manufacturing – discrete, process, automotive, aerospace, semiconductor and more.
- Logistics, warehousing, parcel and freight operators.
- Smart cities, building automation and large industrial campuses.
Where quantum matters
Building with quantum and quantum‑inspired methods
- Quantum sensing for asset monitoring, anomaly detection, navigation, timing and environmental measurement.
- Quantum and quantum‑inspired optimisation for network flows, routing, maintenance planning and resource allocation.
- Quantum‑enhanced modelling and simulation for complex industrial systems and resilience planning.
Defending against the quantum computing threat
- PQC and crypto‑modernisation for OT and IT: control systems, telemetry, VPNs, management and remote‑access channels.
- Quantum‑risk assessments that take into account safety, regulatory and operational constraints.
- Securing quantum‑enabled systems and sensors so they don’t introduce new, poorly understood attack surfaces.
Key challenges in critical infrastructure & industrial
- Legacy OT and ICS equipment with tight safety envelopes and long lifecycles.
- Fragmented ownership between operators, vendors, integrators and service providers.
- Sector‑specific regulation and supervision, often tied to national security.
- Difficulty aligning cyber, engineering, operations and risk on quantum priorities.
- Limited capacity for experiments that might disrupt production or safety cases.

Relevant Case Studies
National Quantum-Security Strategy
Shaping a national quantum‑security and PQC strategy - For a government agency, we developed a quantum‑security strategy covering critical infrastructure, public services and national cryptographic policy. This included threat and impact assessment, sector‑by‑sector prioritisation, reference architectures for PQC adoption, and stakeholder playbooks for regulators, operators and vendors.
Quantum-Safe Signaling and Optimization for Rail Systems
A major metropolitan mass transit authority, operating an extensive rail and subway system, recognized that its ongoing digital modernization brought with it new cybersecurity challenges – especially with the looming prospect of quantum computers. Modern rail systems depend on secure communication: signaling systems send commands to trains, positive train control systems prevent collisions, and operational data about train positions and speeds flow constantly.
Quantum Readiness for a Critical Infrastructure Operator
Building a quantum‑risk and readiness baseline - We worked with a critical infrastructure operator to assess how quantum threats intersected with long‑lived data, OT/ICS systems and national regulatory expectations. The engagement delivered a formal quantum‑risk profile, a maturity and readiness baseline, and a prioritised roadmap covering PQC, network security, sensing pilots and workforce development.
