Q-Bridge: Quantum Workbench

Watch your quantum jobs run live. Design, simulate & run circuits on 7 vendor QPUs — Circuit Architect, Qubit Health, OpenQASM, QEC.

Q-Bridge — A quantum workbench for Apple platforms.

New in v10.2.2 — Real-time job monitoring. Submit a circuit and watch it move from queued to running to done in real time; your job list updates the moment status changes, and finished simulator jobs return real measurement counts you can open right away.

Seven major quantum hardware providers ship seven different physical platforms — superconducting qubits, trapped ions, neutral atoms, tunable couplers, photonics. Each one is good at different circuits. Q-Bridge gives you a single, native Apple app to design circuits, run them on the cloud simulator, compare backend characteristics, and submit jobs across all of them.

Built for quantum researchers, Apple platform developers, and people learning quantum algorithms.

What's in the app (all wired up in v10.2.2)

1. Multi-Vendor Quantum Gateway — Browse and submit to 7 hardware providers from one unified app surface.
2. Circuit Architect — A visual quantum circuit designer with on-screen gate palette and inline OpenQASM preview.
3. Qubit Health Predictor — Visualize T₁/T₂ coherence and gate fidelity per qubit across the topology.
4. Noise-Bug Discriminator — Pattern-based diagnostic that flags noisy qubits and crosstalk hotspots.
5. BB Code Decoder — Decode Bivariate Bicycle quantum LDPC codes directly on your device.
6. QEC Simulator — Surface code distance 3 through 7 with three decoder choices (MWPM, Union-Find, Lookup).
7. OpenQASM Editor — Syntax-highlighted editor with backend-compatible gate set hints.
8. BridgeAdvisor AI — Apple Foundation Models running on-device suggest backend choices based on your circuit shape. No cloud calls. No data uploaded.

Also included: QIR Pipeline · Bloch Sphere · Nighthawk Topology Map · Distributed Topology · Entanglement Schemes · Smart Error Budget · Crosstalk Map · Qubit Reuse · Erasure Simulator · Providence Mode (live vendor weather vane).

Apple-native: SwiftUI, Liquid Glass design system, Universal Purchase (one purchase covers iPhone, iPad, Mac, and Vision Pro), seven-language localization (English / 한국어 / 日本語 / 中文 / Deutsch / Français / Español), full keyboard navigation on Mac, App Intents for Siri.

Privacy: AI inference runs on-device. Your circuit code (QASM) is never uploaded for AI suggestions. API keys are kept in iOS Keychain. Authentication uses short-lived tokens. Free tier works without an account.
