Getting Started​

Installation​

pip install softqcos

Quick Example​

from softqcos import QCOSClient

# Connect to QCOS
client = QCOSClient(api_key="your-api-key")

# Optimize a circuit
result = client.optimize(
qasm="OPENQASM 2.0; ...",
backend="ionq_simulator",
shots=1024
)

print(f"Optimized depth: {result.optimized_depth}")
print(f"Evidence ID: {result.evidence_id}")
