quantumopt

AI-driven quantum circuit compiler using Graph Neural Networks + Claude LLM — tested on real research circuits

What It Does

quantumopt takes your quantum circuit and returns an optimized version that runs more accurately on IBM quantum hardware — with a plain English explanation you can cite in your paper.

Installation

pip install quantumopt

Usage

from qiskit import QuantumCircuit
from quantumopt import compile

# Your research circuit
qc = QuantumCircuit(5)
qc.h(0)
qc.cx(0, 1)
qc.cx(1, 2)
qc.ry(0.5, 0)
qc.rz(0.3, 1)

# Compile and optimize
result = compile(qc, hardware="ibm_brisbane")

# Results
print(result.depth_reduction)    # "31%"
print(result.gate_reduction)     # "32%"
print(result.explanation)        # Claude-generated report
print(result.optimized_circuit)  # Ready to run on IBM

Benchmark Results

Tested on 41 real circuits from QASMbench (published research circuits):

Tested on 10,240 synthetic circuits:

Example Explanation Output

When ANTHROPIC_API_KEY is set, quantumopt generates research-quality explanations:

"Transpilation of the target circuit for IBM Brisbane hardware yielded a 31.6% reduction in circuit depth (128 → 88 layers) and a 31.6% reduction in total gate count (326 → 223 gates). Among the applied optimization passes, merge_rotations contributed most substantially, as consecutive single-qubit rotation gates collapse into single parametrized operations. The resulting reduction in two-qubit gate exposure is particularly consequential for hardware execution, as each eliminated layer directly reduces coherence-time consumption against Brisbane's median T₂ timescales (~100–200 µs)."

How It Works

1. Your circuit is encoded as a Directed Acyclic Graph
2. A trained GNN (82% accuracy) predicts optimization potential and recommends optimization actions
3. Qiskit transpiler optimizes for target hardware
4. Claude generates a hardware-specific explanation you can cite in your paper
