SwiftQuantum: Quantum IDE

New: on-device AI turns plain language into quantum circuits — no network, prompts never leave your device, every result sealed in a tamper-evident record.

The quantum IDE that runs on your device — no cloud required.

SwiftQuantum is a native quantum development environment for iPhone, iPad, and Mac. Design, simulate, and ship real quantum circuits from anywhere — even in airplane mode.

DESCRIBE IT, AND IT BUILDS • Write what you want in plain language, and SwiftQuantum builds a real, runnable quantum circuit for you • Edit, run, and inspect the results without ever leaving the app

SIMULATE ON YOUR DEVICE — EVEN OFFLINE • Clifford (stabilizer) circuits up to 127 qubits, running entirely on-device — verified on a real iPhone in airplane mode • General circuits up to 25 qubits on-device • Your circuits never have to leave your device

TOOLS FOR REAL WORK • An on-device AI coding assistant that helps you build circuits and fix them fast • A QEC (quantum error correction) decoder simulator with Monte Carlo analysis • A circuit linter that catches mistakes before you run • Export to industry-standard OpenQASM and other frameworks, including PennyLane and CUDA-Q — so your work moves with you

AI THAT LIVES ON YOUR DEVICE • Optional: download a compact AI model that turns plain language into circuits entirely on your device — no network at all while it generates • Your prompts stay on your device, always • Every accepted result is sealed into a local, tamper-evident record you can inspect and verify in Settings — and records you sealed before keep verifying • Off by default; turn it on when you want it, delete the download any time

KEEP A RECORD OF WHAT YOU ACTUALLY RAN • Q-Footprints seals each simulation you run on your device into a practice ledger you can verify later • Off by default and entirely optional — and even when it is on, your circuit itself is never sent • Your activity, the gates you have exercised, and your highest qubit counts, shown honestly and separately • Publish a profile others can open, or embed a verified badge on your own site (paid plans) • A seal attests that a run happened — it is not a skill score and not a certification

PROTOTYPE QUANTUM-SAFE CRYPTOGRAPHY • Learn and experiment with post-quantum cryptography, hands-on • Includes a pure-Swift implementation of ML-KEM-768, the NIST-standardized key-encapsulation mechanism (FIPS 203) • Plus a reference implementation of ML-DSA-65 (FIPS 204) for exploring quantum-safe signatures • And an automated migration generator to help you scaffold quantum-safe code

BUILT FOR THE WAY YOU WORK • Native on iPhone, iPad, and Mac • Fully localized in 7 languages • Free to start

Who it's for: quantum students learning by doing, educators teaching with real circuits, and developers building for the quantum-safe future.
