SwiftQuantum vs SQQuantum

Design, run and understand quantum circuits on iPhone, iPad and Mac. SwiftQuantum is a native quantum circuit IDE for students, researchers 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 • Benchmark (Home > Quick Actions, when signed in): median run time per engine with a 95% confidence interval, measured on your device 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 • The error rate chart says where each curve comes from: measured on our engine, measured on your device (distance 3, offline), or a dashed reference formula TAKE YOUR WORK WITH YOU • Import and export OpenQASM; on Team and Enterprise, also convert circuits to PennyLane and CUDA-Q code — each conversion shows its measured state overlap with your circuit, or “Not verified” • Paid plans: inspect a circuit's unitary matrix; Team and Enterprise also 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.

SQQuantum Studio: The Universe in Your Hands Welcome to SQQuantum by Sapiens Qualia—a breathtaking leap in mobile scientific computing. SQQuantum bridges the gap between high-end desktop tensor analysis and accessible mobile education, putting a fully functional, lightning-fast quantum circuit simulator directly onto your iPhone and iPad. Whether you are a university physics student learning the fundamental mechanics of entanglement, a software engineer transitioning into quantum logic, or a researcher testing state-vector mathematics on the go, SQQuantum provides a flawless, professional-grade Integrated Development Environment (IDE) optimized specifically for the Apple ecosystem. OPTIMIZED FOR APPLE SILICON SQQuantum is an engineering masterpiece. Under the hood, it is powered by a custom-written, native C++ state-vector engine utilizing the heavy-duty Eigen mathematical framework. By bridging Swift directly to C++ and compiling natively for Apple’s A-Series and M-Series processors, the app achieves zero-latency, real-time matrix multiplications entirely offline. It natively projects complex quantum physics calculations onto a beautifully fluid, hardware-accelerated SwiftUI canvas without dropping a single frame. POWERFUL FUNCTIONALITY • Dynamic Circuit Canvas: Build complex quantum circuits using multiple qubits. Apply fundamental quantum logic gates including Hadamard (H), Pauli (X, Y, Z), Parametric Phase Shifts (Rx), Controlled-NOT (CX), and Measurement operations. • Interactive 3D Bloch Sphere: Visualize the invisible. Utilizing Apple’s native SceneKit framework, our 3D projector allows you to touch, drag, and rotate the Bloch sphere to intuitively understand qubit vector phases and superpositions in real-time. • Live Probability Distributions: As you build your circuit or drag parameters, the simulator instantly calculates the wave function and renders the exact probability distribution of your quantum states in a vibrant, responsive UI. • Hardware Noise Simulation (NISQ): Experience the reality of modern hardware. Use the dynamic noise slider to inject probabilistic decoherence and environmental noise into your gates, simulating how physical quantum computers actually behave. • Live OpenQASM 3.0 Generation: SQQuantum acts as a true developer tool. As you visually construct your circuit, the app simultaneously compiles industry-standard OpenQASM 3.0 code in a dedicated terminal pane. Copy it with one tap to export and run your exact circuit on real IBM or AWS quantum mainframes. • Instant Entanglement: Instantly load complex quantum phenomena like the Bell State (Quantum Entanglement) and GHZ State with a single tap. PRO iPadOS ARCHITECTURE SQQuantum intelligently adapts to your hardware. On the iPhone, it provides a sleek, highly readable, vertically scrollable interface. On the iPad, the UI transforms into a gorgeous, split-pane professional IDE—featuring a sprawling mathematical workspace on the left, a dedicated hardware inspector on the right, and a full-width code terminal pinned to the bottom. 100% PRIVATE & OFFLINE Science requires focus, not tracking. SQQuantum is 100% offline. It requires zero account sign-ups, utilizes zero cloud processing, contains no advertisements, and collects absolutely zero user data. Your algorithms belong to you.
