What Is Quantum Entropy
Quantum entropy here means non-deterministic randomness derived from real quantum measurements—not from a deterministic algorithm.
Non-deterministic vs pseudo-random
Source
Algorithm (e.g. Mersenne Twister, xorshift)
Physical quantum measurement (particle collapse)
Determinism
Deterministic given the same seed
Non-deterministic; no seed to replay
Verifiability
Cannot prove it was not reproduced
Anchored on-chain; provable via Quantum Job ID
Predictability
In principle predictable if seed is known
Not predictable from prior outputs
Pseudo-random number generators (PRNGs) are fine for many applications—games, sampling, non-security-sensitive use. But when the stakes are high—security, fairness, oracles, AI agents, lotteries, key generation—reproducibility and predictability become risks. An attacker who knows or influences the seed can predict or replay “random” outcomes.
Quantum entropy is non-deterministic: each measurement is a physical event. There is no seed to steal or replay. Quantropy then anchors each request to a Solana transaction, so anyone can verify that a given entropy output came from the network and was not forged or replayed.
Why it matters for high-stakes use cases
Security — Nonces, session IDs, and cryptographic material derived from quantum entropy cannot be reproduced by an attacker who observes past outputs.
Fairness — Lotteries, leaderboards, and game outcomes can be audited on-chain; no “rigged” seed.
Oracles & DeFi — Randomness for oracles and protocol logic is verifiable and resistant to manipulation.
AI agents — “Quantum Seeds” for autonomous agents make behavior non-replayable and un-clonable; see AI Agent Security.
Quantropy supplies this entropy via a low-latency API backed by a multi-vendor QPU fleet, with every request tied to a Quantum Job ID and on-chain settlement.
