The $20 Million Question: Why a Special-Purpose Quantum Computer Built to Break Encryption Is Closer Than Most Enterprise Planning Cycles Assume
March 31, 2026 / 16 min read / 8 references / Qtonic Quantum Research Team
Two preprints collapse resource estimates for breaking elliptic-curve cryptography by orders of magnitude. A purpose-built Shor machine could cost $13-40M.
- Resource estimates for special-purpose quantum attacks have moved into ranges that boards can understand.
- The immediate risk is not instant decryption; it is planning against long-lived secrets and slow migration cycles.
- A defensible response starts with inventory, data horizon classification, and migration sequencing.
Decision takeaway
Translate resource-estimate compression into data-horizon and migration-budget decisions.
