Company Interview / The quantum clock is ticking

Key points:

Quantum computing seen as a threat to all digital encryption, not just cryptoBitcoin and Ethereum positioned as visible testing grounds for post‑quantum solutionsBanks and governments viewed as slower, less transparent on quantum‑resistant upgrades

Paul Quickenden from Swyftx sets out why quantum computing is, in his view, a systemic cyber risk rather than a narrow “crypto problem”. Quickenden argues that quantum machines could break the cryptographic algorithms underpinning everything from crypto assets to online banking, government portals and health records. He points to Google’s February comments suggesting a potential pull-forward of the quantum timeline to around 2029, which he says is unsettling markets and forcing earlier preparation.

Quickenden states that criminals are already harvesting encrypted data now, expecting to decrypt it in five to ten years, making long-lived records such as IDs and medical files especially vulnerable. He highlights major crypto networks such as Bitcoin and Ethereum as early testing grounds for post‑quantum security, suggesting Bitcoin has the most work ahead while other tier‑one chains have clearer roadmaps. In his view, banks and governments are moving more slowly and less transparently, and he urges consumers to question providers about their post‑quantum plans.

He compares the looming shift to the web’s move from unsecured connections to padlocked HTTPS, calling it a massive coordination challenge. Quickenden notes that post‑quantum algorithms exist and have been tested, but says broad migration across financial and government systems could take many years.
