SwiftQuantum: Quantum IDE

Design, run and understand quantum circuits on iPhone, iPad and Mac. SwiftQuantum is a native quantum circuit IDE for students, educators and developers. Build a circuit, run it, and see what it does — with clear rules about where your work goes. BUILD CIRCUITS YOUR WAY • Drag-and-drop editor with the standard gates: H, X, Y, Z, S, T, rotations, CNOT, CZ, SWAP, Toffoli and more • Start from ready-made circuits such as Bell and GHZ states • See measurement probabilities for every run RUN ON YOUR DEVICE • Free plan: the Standard engine runs circuits up to 10 qubits on your device • Paid plans: Turbo and HyperCore engines simulate general circuits up to 25 qubits on your device • Every engine computes exactly the circuit you drew, in shot mode too • On Team and Enterprise, Clifford (stabilizer) circuits up to 127 qubits run on your device — tested on a real iPhone in airplane mode • A circuit goes to our server only when it needs it (more than 25 qubits with non-Clifford gates), and only after you tap Send AI THAT STAYS ON YOUR DEVICE • Optional: download a compact AI model once, describe a circuit in plain language, and get a circuit back — generated with no network • Your prompts stay on your device • Accepted results are sealed into a local, tamper-evident record you can check in Settings. A seal shows the generation happened on your device; it does not guarantee the circuit is correct • Off by default; delete the model whenever you like ERROR CORRECTION (TEAM AND ENTERPRISE) • Run surface-code experiments on our engine: choose the code distance, physical error rate and decoder • See the logical error rate from Monte Carlo shots with a 95% confidence interval TAKE YOUR WORK WITH YOU • Import and export OpenQASM, and convert circuits to PennyLane and CUDA-Q code • Inspect a circuit's unitary matrix and compare gate fidelity KEEP A RECORD OF WHAT YOU RAN • Q-Footprints: an opt-in practice log of the simulations you run on your device • Your circuit itself is never sent — only the shape of the run • A seal shows a run happened; it is not a skill score or a certification BUILT FOR THE WAY YOU WORK • Native on iPhone, iPad and Mac • Available in 7 languages • Free to start Who it's for: students learning quantum computing by doing, educators teaching with real circuits, and developers prototyping quantum programs. — SwiftQuantum is free to download with optional auto-renewable subscriptions.
