Hybrid Quantum-AI Code & Systems Preview

🧠 Code & Systems Preview

We engineer explainable, quantum-inspired AI systems for regulated, low-latency, high-integrity applications. Below are selected components and logic excerpts from quantum-inspired explainable AI, quantum-powered anomaly detection, and supporting hybrid quantum-classical ML pipelines.

🔍 Feature Attribution via Hilbert Activation Norms

A quantum-inspired explainable AI (QIXAI) Keras-based CNN outputting a dynamically generated relevance heatmap. Integrates mutual information scoring and cosine similarity for real-time interpretability.

def hilbert_activation(x):
    norm = K.sqrt(K.sum(K.square(x), axis=-1, keepdims=True))
    return x / (norm + K.epsilon())

Tech: Keras, Numpy, Custom QIXAI layer API

Use Case: Real-time medical image diagnosis

📈 Interpretable Output Generator (IOG)

An inline decision trace generator, providing justification trails during inferencing. Layered inside a TensorFlow or PyTorch quantum inspired interpretability lifecycle system deployment.

# Sample IOG output trace (text form)
"This decision was made on 2025-06-10 at 14:05 UTC.
It was driven primarily by domain entropy (37%) and query type rarity (34%),
confirmed by feature activation cluster B6-G. Model version: V3.1."
  

Tech: PyTorch Lightning, TorchServe, Kafka

Use Case: DNS anomaly scoring pipelines

📚 Hybrid NLP Circuit on AWS Braket

A toy example of a Braket Hybrid Job to execute a QNLP sentence encoding circuit on Rigetti, using PyTorch and PennyLane orchestration.

# hybrid_main.py
@braket_hybrid_job
def run(job: HybridJob):
    device = qml.device("braket.aws.qubit", wires=4)
    @qml.qnode(device, interface="torch")
    def circuit(x):
        qml.AngleEmbedding(x, wires=range(4))
        return qml.expval(qml.PauliZ(0))
    return circuit(torch.tensor([0.1, 0.3, 0.2, 0.4]))

Tech: PennyLane, AWS Braket Hybrid, Rigetti

Use Case: Experimental QNLP pipeline (Q-PAD)
