Allianz report: quantum may crack bank encryption before it turns a profit
mikeflache · x · 2026-09-14
An Allianz report frames quantum computing as two clocks ticking side by side: one toward economic value, one toward cryptographic catastrophe, with no one sure which strikes first.
- Breaking Bitcoin's elliptic-curve crypto needs roughly 1,250–1,450 logical qubits — below the 4,700–7,500 required for profitable applications like derivative pricing, so the destructive use case arrives first
- Shor's algorithm has been public since 1994; adversaries only lack the hardware
- Encrypted data harvested today can be decrypted once quantum machines mature
- Only 35% of large organizations have completed a cryptographic inventory, and NIST deprecates today's vulnerable algorithms after 2030
