# Random quantum circuits: 5 qubits (ANU)

500 random quantum circuits on 5 qubits, depth 10, using the gates `h`, `x`, `sx`, `rz`, `cx`, with every qubit measured at the end. Each row is one circuit, as `qasm` (OpenQASM 2.0) and as `instructions` (JSON).

The dataset was generated from a seed drawn from `anu_aws_001` through
[Light Rider](https://entropy.lightriderinc.com). The seed comes with a signed receipt, so anyone
can check where the data came from and regenerate it exactly.

## How to verify

```bash
pip install lightrider-huggingface
```

```python
import lightrider_huggingface as lrhf

print(lrhf.verify("LightRider-Inc/random-quantum-circuits"))
```

This needs no Light Rider account. It prints each check as PASS or FAIL.

## How verification works

1. **The receipt is genuine.** Light Rider signs every draw's receipt (Ed25519). The public key is
   at [entropy.lightriderinc.com/api/v1/public-key](https://entropy.lightriderinc.com/api/v1/public-key).
2. **The seed is that draw's output.** The signed receipt includes a hash of the exact bytes drawn,
   so a seed from any other draw doesn't match.
3. **The data follows from the seed.** Generation is deterministic, so `verify` rebuilds every row
   from the seed and parameters and compares it with the published data.

## What this doesn't claim

That quantum randomness makes this dataset better than one built with a good classical generator.
It's an alternative source whose origin you can check. A receipt also can't show that the publisher
drew only once; its timestamp shows when the draw happened.
