How it works

Submit a circuit. Receive a mathematically certified result with a cryptographically signed receipt.

01

Submit

Send your OpenQASM circuit via REST API or MCP.

02

Compute

Our engine determines the peak measurement outcome.

03

Certify

Inverse verification proves the result: C†C = |0⟩.

04

Receive

ECDSA-signed receipt. Independently verifiable.

Why QuantumCollapse

Deterministic

Same circuit, same answer. Every time. No sampling, no shot noise, no probabilistic approximation.

Self-Verifying

Every GOLD-certified result includes a mathematical proof. We compute C†C and verify it returns |0⟩. If the proof fails, we tell you.

Sovereign

Your circuit is never stored. We compute a SHA-3 hash for the receipt, then discard the input. Regional processing available for enterprise.

Scale

Verified results up to 1,000,000 qubits. Ring, chain, and heavy-hex topologies supported.

One API call

Submit QASM. Get a certified result with a cryptographic receipt.

curl -X POST https://api.quantumcollapse.io/verify \
