Quantum computing, sensing and communication for payments and market infrastructure

Quantum technology could eventually break public-key cryptography that secures payments and settlement. On this platform it is examined as a migration risk: which pergalan use vulnerable cryptography, how long migration takes and what standards apply.

What quantum computing, sensing and communication does here.

Quantum computing, sensing and communication exploit quantum mechanical effects to process information and make measurements. They promise new capabilities and pose a long-term threat to current public-key cryptography. In financial stability, cyber and digital resilience and digital public infrastructure, quantum technology assessment informs when to migrate critical pergalan to quantum-resistant cryptography. Quantum sensing may improve navigation and subsurface monitoring for infrastructure. The canonical description is on the STEM Commons.

Cryptographic inventory

Systems and messages using vulnerable public-key algorithms are inventoried, prioritising long-lived data and hard-to-change components.

Migration planning

Timelines to adopt NIST post-quantum standards are planned against system replacement cycles and vendor readiness.

Harvest now, decrypt later

Data intercepted today that must stay confidential for years is identified as an early priority for quantum-resistant protection.

No observed data enters this model: it runs on the teaching values set by the controls, to be replaced with a programme’s own evidence.

How a shock to assets becomes a system loss. Illustrative teaching model: it runs on the values set by the controls, not on measured data. Methods: DebtRank (Battiston and others (2012), Scientific Reports 2:541); Differential DebtRank (Bardoscia and others (2015), PLOS ONE 10); Contagion in financial networks (Gai and Kapadia (2010), Proc. R. Soc. A 466).

05Exposure, loss and capital

What it means for exposure, loss and capital.

The exposure, loss, scenario and capital views a risk officer, supervisor or ministry of finance would ask for, with the frameworks they report against. Structures follow supervisory and actuarial practice. Values are illustrative: never prices, ratings or advice.

Transmission channels

How a shock in quantum computing, sensing and communication for payments and market infrastructure reaches credit, market, underwriting, liquidity and operational risk, and feeds back.

Channel structure after the Basel Committee’s work on climate-related risk drivers and transmission channels; links shown are typical paths, not estimated exposures.
