# ⚛️ Q-Route-70B: Quantum Hardware Compiler Model Card

**Q-Route-70B** is a domain-adapted frontier AI compiler model fine-tuned on `Llama-3.3-70B-Instruct` via the **Adaption Labs AutoScientist** platform. It compiles abstract OpenQASM 2.0 quantum circuits to strictly adhere to physical target QPU connectivity graphs (Line, Ring, Star, Grid, and IBM Heavy-Hex hardware topologies).

## Model Training

A LORA adapter for `meta-llama/Llama-3.3-70B-Instruct-Reference`. This model was trained with SFT using [Adaption](https://adaptionlabs.ai)'s AutoScientist on the quantum_circuit_routing dataset.
