SwiftQuantum vs SQQuantum

Design a quantum circuit, run it on your own device and watch every qubit — on iPhone, iPad and Mac. SwiftQuantum is a quantum circuit IDE for learners, students, educators and developers. Drag gates onto the canvas, tap Run and see the result as a Bloch sphere, a histogram and a state vector. Then take any circuit to Python as a Qiskit script, on every plan. RUN IT ON YOUR DEVICE • Free: circuits up to 10 qubits • Scholar: any circuit up to 25 qubits • Master and Enterprise: Clifford circuits up to 127 qubits, even offline • Circuits with non-Clifford gates run up to 25 qubits. Larger ones aren't simulated anywhere: the app tells you what to change and sends nothing • A circuit leaves your device only after you tap Send BUILD CIRCUITS YOUR WAY • Drag-and-drop editor with ready-made circuits such as Bell and GHZ states • Every gate is free: H, X, Y, Z, S, T, RX, RY, RZ, CNOT, CZ, SWAP, Toffoli and Fredkin • Three engines — Standard (Free), Turbo (Scholar) and HyperCore (Master) — each computes exactly the circuit you drew, in shot mode too • Export (OpenQASM, Qiskit), on every plan: OpenQASM 2.0 and a Qiskit Python script that runs as is with Qiskit 1.x (pip install qiskit); every qubit is measured at the end. OpenQASM 2.0 import too • Larger text and VoiceOver support on the circuit editor and the subscription screen SEE WHAT YOUR QUBITS DO • A Bloch sphere for each qubit, plus a measurement histogram and the state vector for every run • Export results: PNG and CSV on Scholar; LaTeX, PDF and SVG on Master • Paid plans: view the unitary matrix of small circuits; Master also compares gate fidelity ERROR-CORRECTION LAB (MASTER AND ENTERPRISE) • Surface-code experiments: choose the code distance, physical error rate and decoder • Logical error rate with a 95% confidence interval, computed on our servers (network needed) • Every curve says where it came from: our servers, your device (distance 3, offline) or a dashed reference formula 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 without a network on supported devices • Your prompts stay on your device. Off by default; delete the model any time • Accepted results are sealed in a local, tamper-evident record: proof of where a circuit was made, not that it is correct NUMBERS YOU CAN CHECK • Benchmark (signed in): median run time per engine with a 95% confidence interval, measured on your device • Master and Enterprise: convert circuits to PennyLane and CUDA-Q code; each conversion shows its measured state overlap with your circuit, or "Not verified" • Q-Footprints: an opt-in log of your on-device runs that records only the shape of each run, never the circuit. Not a score or a certificate PLANS — FREE TO START • Free: 10 qubits, 10 simulations a day when signed in, 5 saved circuits • Scholar: 25 qubits, 100 simulations a day, 50 saved circuits • Master: Clifford circuits up to 127 qubits, 2,000 simulations a day, 1,000 saved circuits • Enterprise: contact us All results are classical simulations; SwiftQuantum does not run circuits on quantum hardware. — SwiftQuantum is free to download with optional auto-renewable subscriptions. Payment is charged to your Apple ID at confirmation of purchase and renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.

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. Step into the mathematical fabric of the universe. Download SQQuantum Studio today and start building the future.
