What is quantum risk in energy and critical infrastructure?
The answer
Quantum risk in energy is a national-security perimeter: grid control systems, pipeline operations, and plant safety systems run on cryptography with the longest replacement cycles in the economy — infrastructure installed today operates into the quantum era by default. Migration is therefore mandated earliest exactly where upgrades are hardest.
The operational reality is embedded systems: industrial controls cannot be patched like laptops, so quantum-safe migration arrives through procurement — every new turbine, substation, and control system tendered from now on carries post-quantum requirements. The vendor market forms around that procurement wave.
The upside file is real but longer-dated: quantum optimization against grid balancing and materials discovery for storage — watched as research partnerships, priced as options.
