About This Quantum Circuit Simulator and Quantum DSL
This free quantum circuit simulator and quantum computing playground enables hands-on exploration of quantum computing concepts through a compact quantum DSL.
Created by Anup Dharangutti with a focus on clarity and minimalism, it provides real-time visualization of quantum states, probability distributions, and Bloch sphere visualization.
The simulator supports standard quantum gates (Hadamard, Pauli, CNOT) and shot-based measurements, making it ideal for students, educators, and developers learning quantum algorithms.
Editing and visualization run in the browser; the API calculates the statevector, samples measurements, and generates the SVG diagram. Execution architecture →
Circuits can be shared through URL encoding, enabling collaborative learning without accounts or installations.
The tool includes OpenQASM export for interoperability with other quantum platforms.
Designed for accessibility and simplicity, this simulator bridges the gap between theoretical quantum mechanics and practical circuit design, with version-aligned documentation for bounded experimentation.
AutomationGlance is a browser-first environment for learning quantum concepts, simulating bounded quantum circuits, formulating optimization problems, classically validating small models, and exporting artifacts for further experimentation.
Structural heuristic (0–1): depth, gates, interaction pairs and width. Definition and limits
Scope note: Structural analysis and protocol detection are accurate. Entanglement reporting is based on gate interactions, not analysis of the final quantum state. Observed‑behavior summaries are approximate; refer to raw counts for exact probabilities.

Feature map & implementation notes
Advanced Analysis & Tooling
State Vector Explorer: Expanded, monospace table for amplitudes, probabilities, and phases with inline scrolling for large registers.
Syntax Highlighting: Mirror-style DSL highlighting aligned pixel-for-pixel with the editor for predictable cursor placement.
Download Diagram: One-click SVG (and PNG) downloads with inline styles preserved for crisp offline viewing.
Performance Mode (optional): Toggle to trim animations and shadows when you need a lighter UI footprint.
Complexity Score (optional): A normalized structural heuristic for comparing circuits within AutomationGlance; not a measure of computational hardness.
Timeline View (optional): Future visual for sequencing gates by depth.
Describe qubits, gates, and measurements line-by-line.
qubits N sets the register size.
Use single-qubit gates like H 0 or X 2.
Entangle with CX a b (control, target).
MEASURE i records counts for qubit i.
Running & sharing
