Threshold-Convergent Systems: The Shared Mathematical Structure Governing Quantum Error Correction and Oracle Consensus for Physical Asset Verification and Collateralisation Under Basel IV

The Takeaway
Quantum error correction and financial asset verification seem like unrelated fields. This research identifies a shared structure called threshold-convergent systems that governs both. Both systems rely on suppressing noise through a specific type of Bayesian consensus to reach a reliable outcome. This law explains how quantum computers stay stable and how banks can verify collateral under the Basel IV regulations. Finding this link allows engineers and economists to use the same tools to solve problems of trust and error in their respective worlds.
From the abstract
<div> This paper identifies and formally characterises a class of distributed information systems — threshold-convergent systems — in which individual participants are unreliable, but a mathematically definable critical threshold exists such that when participant error rates fall below it, adding more participants produces exponential improvement in system-level reliability. Above the threshold, scale amplifies noise. Below it, scale suppresses noise exponentially. We establish four axiomatic pr
