Features
Everything you need for quantum circuit design and simulation
Visual Circuit Editor
Drag-and-drop quantum gates onto qubit wires with our intuitive SVG-based circuit canvas.
QASM Code Editor
Full-featured Monaco editor with QASM 2.0 syntax highlighting, auto-complete, and validation.
On-Device Engines
JS and Rust→WASM state-vector engines and a CHP stabilizer engine for Clifford circuits, all running on your device. Team+ can opt in to the HyperCore server for Clifford circuits.
Bloch Sphere Visualization
Real-time 3D Bloch sphere representation of qubit states with interactive rotation.
QEC Decoder
Rotated surface-code Monte Carlo with MWPM or Union-Find decoding, run on the SwiftQuantum engine server (Team+).
Polyglot Transpiler
Export circuits to Qiskit, PennyLane, CUDA-Q, and OpenQASM 3.0 with one click.
