Integrating Gemini and Claude into Quantum Experiment Notebooks

Hook: Stop fighting fragmented tooling — use Gemini and Claude as practical helpers in your quantum notebooks

If your team spends more time stitching SDKs, simulators and CI pipelines together than experimenting with algorithms, you are not alone. Quantum software development in 2026 still faces fragmented tooling, poor integrations, and a steep ramp for developers. This guide shows how to embed Gemini (Google) and Claude (Anthropic) directly inside Jupyter and Zeppelin notebooks to generate circuits, explain experimental results, and produce deployment scripts — with concrete code, prompts, and automation patterns you can copy into your projects today.

What you'll get — actionable outcomes

• Notebook-ready helper functions to call Gemini and Claude from Python/Scala notebooks.
• Prompt templates for robust circuit synthesis targeting Qiskit and PennyLane.
• Patterns to validate generated circuits, analyze results, and automate fixes.
• Examples where LLMs produce Dockerfiles, GitHub Actions and Terraform for deployment.
• Security, cost and benchmarking guidance aligned with late-2025/early-2026 trends like Gemini's expanded integration and Anthropic's developer tooling.

Why LLM helpers matter for quantum development in 2026

Since late 2024 and into 2025, LLMs matured from assistants that suggest snippets to developer tools that execute multi-step reasoning, synthesize code, and interact with external APIs. High-profile deals (e.g., Google's Gemini being embedded in major ecosystems) and Anthropic's push with developer products (Claude Code / Cowork) mean modern LLMs are optimized for coding workflows and agents. For quantum teams this unlocks three practical gains:

• Rapid prototyping: Generate circuits and tests fast, reducing manual boilerplate.
• Explainability: Ask an LLM to interpret measurement histograms, noise signatures and suggest mitigations.
• Automation: Produce reproducible deployment artifacts from the same notebook where you ran your experiments.

Architecture: how notebooks talk to LLMs and quantum backends

The common, secure pattern is a three-tier flow:

1. Notebook (Jupyter/Zeppelin) runs code – orchestration layer.
2. LLM API (Gemini / Claude) used for synthesis, explanations and script generation.
3. Quantum SDKs (Qiskit, PennyLane, Cirq) and simulators/backends (Aer, Pennylane-Lightning, Braket) for execution and validation.

Important: keep the LLM calls ephemeral and validate all generated code before execution. Never store plain API keys in notebooks; use environment variables, secret managers, or cloud Key Vaults.

Security & secrets: practical setup

Use these minimal best practices inside notebooks and Zeppelin interpreters:

• Store API keys in environment variables (e.g., GEMINI_API_KEY, CLAUDE_API_KEY) or cloud secret stores, not in the notebook cells.
• Use short-lived tokens where possible (Google IAM/Workload Identity, Anthropic tokens via managed secrets).
• Sanitize/validate any code the LLM returns before executing it. Run generated code in an isolated container (e.g., Docker) for CI deployment steps.

Quick install: Python deps for Jupyter

Install the typical stack in a virtualenv or conda env:

pip install qiskit pennylane requests anthropic google-cloud-aiplatform python-dotenv

Note: use the official cloud SDKs if you want native client libraries. The examples below use simple HTTP wrappers for clarity so they translate to Zeppelin shell/Scala cells too.

Connecting from a Jupyter cell: Gemini and Claude client wrappers

Below are minimal helper functions you can paste into a notebook. They demonstrate how to call Gemini (via Google Cloud Vertex AI REST) and Claude (Anthropic API). Replace env lookups with your secret manager in production.

import os
import time
import requests

GEMINI_KEY = os.getenv('GEMINI_API_KEY')
CLAUDE_KEY = os.getenv('CLAUDE_API_KEY')

def call_gemini(prompt, model='gemini-1.5-pro', max_tokens=1024):
    url = 'https://us-central1-aiplatform.googleapis.com/v1/projects/YOUR_PROJECT/locations/us-central1/publishers/google/models/%s:predict' % model
    headers = {
        'Authorization': f'Bearer {GEMINI_KEY}',
        'Content-Type': 'application/json'
    }
    payload = { 'instances': [{'content': prompt}], 'parameters': {'maxOutputTokens': max_tokens} }
    r = requests.post(url, json=payload, headers=headers)
    r.raise_for_status()
    return r.json()

def call_claude(prompt, model='claude-2.1', max_tokens=1000):
    url = 'https://api.anthropic.com/v1/complete'
    headers = {
        'x-api-key': CLAUDE_KEY,
        'Content-Type': 'application/json'
    }
    payload = {
        'model': model,
        'prompt': prompt,
        'max_tokens_to_sample': max_tokens
    }
    r = requests.post(url, json=payload, headers=headers)
    r.raise_for_status()
    return r.json()

Notes

• Gemini usage via Vertex AI may require OAuth access tokens and the Google Cloud SDK (gcloud). The above shows a simplified REST call; swap in google-auth where you need OAuth.
• Anthropic's endpoints and model names change; check the latest docs and use the official client in production.

Generating a Qiskit circuit: prompt design and execution

Good prompt engineering matters. Give the LLM the SDK, constraints and a short test case. Example: request a 4-qubit GHZ-like circuit optimized for minimal two-qubit gates.

circuit_prompt = '''
You are a Python assistant. Generate a Qiskit function build_circuit(n_qubits: int) -> QuantumCircuit that constructs an n_qubit GHZ-like state optimized to use O(n-1) CX gates and returns the circuit object. Use qiskit import statements and include only code. Do not include explanations.
Target Qiskit version: 0.48
Example call: build_circuit(4)
'''

resp = call_claude(circuit_prompt)
code = resp['completion'] if 'completion' in resp else resp['choices'][0]['text']
print(code)

The LLM will typically return a code block. Extract and run it safely by writing to a temporary file and running unit checks before executing in your environment. Example of validation+execution:

import tempfile
from pathlib import Path

code_text = extract_code_block(code)  # user-defined regex extractor
file_path = Path(tempfile.gettempdir()) / 'gen_circuit.py'
file_path.write_text(code_text)

# Basic static check: ensure only qiskit imports exist
if 'os.system' in code_text or 'subprocess' in code_text:
    raise RuntimeError('Unsafe content: system calls detected')

# Import the generated module and instantiate circuit
import importlib.util
spec = importlib.util.spec_from_file_location('gen_circuit', str(file_path))
module = importlib.util.module_from_spec(spec)
spec.loader.exec_module(module)
qc = module.build_circuit(4)
print(qc)

Simulate and validate the generated circuit

After generation, run the circuit on a local simulator and send the numeric results back to the LLM for interpretation and improvement suggestions.

from qiskit import Aer, transpile, assemble
from qiskit.visualization import plot_histogram

sim = Aer.get_backend('aer_simulator')
transpiled = transpile(qc, sim)
qobj = assemble(transpiled, shots=2048)
job = sim.run(qobj)
counts = job.result().get_counts()
print(counts)

# Ask the LLM to explain the counts and suggest fixes
explain_prompt = f"The circuit produced the following measurement counts: {counts}. Explain likely noise sources and how to make fidelity better for a GHZ on superconducting qubits. Give code changes in Qiskit if possible."
resp = call_gemini(explain_prompt)
print(resp)

From explanation to automated repair

Use the LLM's suggestions to automatically produce a patch. Keep automation conservative: generate a patch, run unit tests, then ask the LLM to propose tests for the patch.

patch_prompt = f"Given this circuit code:\n{code_text}\nAnd these suggestions: . Return a unified diff patch to implement the fixes. Only output the patch." 
patch_resp = call_claude(patch_prompt)
patch_text = patch_resp['completion']
# Apply the patch using python patch tools or git apply after review

Generating deployment scripts from the same notebook

LLMs shine at producing reproducible deployment artifacts. Ask for a Dockerfile, GitHub Actions workflow, and a Terraform snippet for a chosen cloud quantum provider. Example prompt:

deploy_prompt = '''
Produce three files:
1) Dockerfile that installs Python 3.11, Qiskit, PennyLane, and necessary system deps.
2) .github/workflows/ci.yml that runs tests and builds a Docker image on push.
3) terraform/main.tf to provision an AWS EC2 with Docker and secrets for GEMINI/CLAUDE access via AWS Secrets Manager.
Return only the three files separated by triple dashes.
'''

deploy_resp = call_gemini(deploy_prompt)
print(deploy_resp)

After generation, validate syntax (docker build --no-cache --target=validator), run the GitHub Actions locally with act or in a sandbox, and rotate any secrets before use.

Automation patterns: chaining LLM calls with execution

For repeatable experiments, build a pipeline in the notebook that orchestrates:

1. Generate circuit (LLM)
2. Run simulation (local/hybrid)
3. Analyze results (LLM)
4. Patch circuit or produce deployment artifacts (LLM)
5. Push to CI/CD (git commit + push)

You can implement this with a small orchestrator function in Python. Below is a simplified loop that retries synthesis until a simple fidelity threshold is met.

def iterative_synthesize(target_fidelity=0.9, max_iters=3):
    for i in range(max_iters):
        code = call_claude('Generate the Qiskit circuit code...')['completion']
        # validate & run (as above)
        fidelity = run_fidelity_test(code)
        if fidelity >= target_fidelity:
            return code
        # ask LLM for improvements using counts
        advice = call_gemini(f"Fidelity {fidelity}. How to improve?")
        # apply suggested patch after human review
    raise RuntimeError('Could not reach target fidelity')

Using LLMs inside Apache Zeppelin (Scala/Java)

Zeppelin supports multi-language notebooks. Two practical ways to call LLMs from Zeppelin:

• Use the Python interpreter (%python) and the same wrappers as Jupyter.
• Use a shell or Scala cell and call the REST endpoints with curl or a lightweight HTTP client. Example Scala snippet (shell style) shown below:

%sh
curl -X POST https://api.anthropic.com/v1/complete \
  -H 'x-api-key: $CLAUDE_KEY' \
  -H 'Content-Type: application/json' \
  -d '{"model":"claude-2.1","prompt":"Generate a 3-qubit circuit in Qiskit...","max_tokens_to_sample":600}'

When running on shared clusters, ensure tokens live in cluster-wide secret stores and that per-user access is audited.

Benchmarks and cost considerations (practical guidance, 2026)

By early 2026, teams we work with report the following real-world trade-offs:

• Latency: Gemini (Vertex) often has lower latency for multimodal and code-heavy prompts when hosted near your cloud resources; Claude excels at long-form reasoning with slightly higher token throughput cost.
• Token cost: Both vendors offer models that target dev workflows at different price points. Measure token use per prompt and cache repeated pattern prompts (e.g., templates + few-shot examples) to minimize cost.
• Reliability: Use local simulators for fast iteration but reserve real device runs to validate performance; billable runs on QA/QPU backends are expensive and should be gated behind CI/CD checks. For teams hosting inference on-device or on small clusters, consult hardware benchmarking guidance such as the AI HAT+ 2 benchmarking to understand tradeoffs.

Example micro-benchmark snippet to measure latency and token size:

import time
start = time.time()
resp = call_gemini('Generate a small Qiskit function...')
print('Latency', time.time() - start)
# Estimate tokens conservatively based on prompt length (or vendor token tools)

Best practices & common pitfalls

• Never run unreviewed code: auto-generated code should go through linting and unit tests. Use static analysis tools to detect suspicious calls.
• Prompt injection: Treat LLM outputs as untrusted; attackers could manipulate content if prompts include user data from experiments. Consider hardening agents and desktop helpers per guidance on how to harden desktop AI agents.
• Version pinning: Pin SDK and model versions in reproducible environments to avoid silent drift.
• Instrumentation: Log LLM prompts and responses (redact secrets), plus experiment metrics to trace regressions. Integrate these logs into an observability playbook such as Site Search Observability & Incident Response for robust tracing.
• Human-in-the-loop: For deployment artifacts, require a code review step before CI publishes to production clouds. Consider developer onboarding patterns from modern onboarding guides when rolling out reviews.

Advanced strategies & future predictions (2026)

Looking ahead in 2026, expect three trends that will directly impact LLM-assisted quantum development:

• Tool-enabled LLMs: LLMs will increasingly run with safe, sandboxed tool access (remote simulators, verifiers) allowing them to propose and validate code without returning raw instructions only.
• Hybrid orchestration standards: Vendors and open-source projects will converge on metadata formats for circuits and tests so LLMs can reliably patch and benchmark code across SDKs.
• On-premise/edge LLM inference: For IP-sensitive quantum algorithms, expect more teams to host Claude/Gemini-like models in private inference clusters with lower latency to local QPUs and simulators. Consider hardware and networking tradeoffs (see AI HAT+ 2 benchmarking) and prepare for low-latency requirements discussed in broader networking predictions such as 5G, XR and low-latency networking.

"More than 60% of users now start tasks with AI" — this user behavior shift means embedding LLMs into developer workflows is no longer experimental; it's a baseline productivity tool. (PYMNTS, 2026)

Checklist: What to do in the next hour

1. Create a safe secrets store for GEMINI_API_KEY and CLAUDE_API_KEY.
2. Install the minimal libs: qiskit, pennylane, requests.
3. Paste the client wrappers into a new Jupyter notebook and validate connectivity with a harmless prompt.
4. Ask the LLM to generate a simple 3-qubit circuit and run it on the local simulator.
5. Iterate: ask the LLM to explain the results and suggest a fix; validate code via automated tests.

Closing: Use LLMs as copilots — but keep control

Gemini and Claude are powerful helpers that accelerate the painful parts of quantum software development: boilerplate, explanation and deployment artifacts. By embedding them into notebooks, you can compress the path from idea to validated experiment and from prototype to production script. The pattern we recommend in 2026 is simple: generate, validate, instrument, and human-review. With careful security and cost controls, you can safely harness LLMs to make your quantum team productive faster.
