New Technology Could Accelerate Quantum Threat Timeline
This briefing highlights advances in quantum computing technology that could impact the quantum threat timeline. One such development is the proposal of a new fault-tolerant quantum computing architecture (Pinnacle Architecture) which could significantly reduce the number of physical qubits needed to break traditional encryption. The authors caution that this development may not be as impactful as it seems, given it was already widely known that quantum hardware not restricted to nearest-neighbour connectivity could require fewer physical qubits overall.
The major regulatory development of note is updated guidance from Germany’s Federal Office for Information Security (BSI), which now recommends phasing out traditional public-key cryptography by 2030–2031, especially for high-security use cases. The regulator cites “harvest now, decrypt later” risks, where encrypted data collected today could be decrypted in the future.
