What problem does it solve? Designing and validating small quantum circuits requires a simulator that shows the full statevector, per-qubit Bloch vectors, and Born-rule probabilities, plus a repeatable way to prove the circuit is correct before sharing it. ## Core Features & Use Cases - Circuit validation and simulation: Validates circuit.json (1–8 qubits, up to 256 gates, H/X/Y/Z/S/T/SDG/TDG/RX/RY/RZ/CX/CZ/SWAP) and computes the exact normalized statevector with a shared Node/browser engine. - Interactive viewer build: Embeds the circuit into a standalone index.html where users can edit gates, scrub the timeline, adjust rotation angles, view Bloch spheres and amplitudes, and sample shots. - Automated proof and screenshots: Runs Node-based statevector proofs and Playwright-driven browser checks that capture screenshots and performance data, writing a readiness verdict to .harness/verdict.json. - Use Case: Define a Bell state in circuit.json, run the build script to generate the interactive simulator, then run the proof script to confirm the 50/50 |00⟩/|11⟩ distribution before handing the page to a colleague. ## Quick Start Create a circuit.json describing your qubits and gates, then ask the agent to build and prove the quantum circuit with the quantum skill.
