Browser-native quantum simulator

Learn Quantum Computing by building circuits that run.

Drag gates onto qubit wires, run the circuit in your browser, and read the result. Quanta — your AI quantum guide — explains what just happened, at your level.

The workspace

This is the whole product — one screen

Editor, circuit grid, probability histogram, Bloch sphere and Quanta, side by side. Place a gate and the simulation updates; press Run and the distribution is recomputed in the browser.

What you can do

Read it, build it, then ask about it

Learn with guided chapters

Thirteen chapters from qubits and superposition through entanglement, Qiskit, Grover's algorithm, BB84 and error correction. Each lesson has an interactive visual and a short quiz; section quizzes unlock the next level.

13 chapters · 3 sections · quiz-gated progression

Build and simulate circuits

Drag H, X, Y, Z, S, T, CNOT, Toffoli and measurement onto qubit wires. A statevector simulator runs in your own browser — no account, no queue, no install — and the histogram and Bloch sphere update as you place gates.

Up to 14 qubits · 16,384 amplitudes · runs locally

Ask Quanta about your own circuit

Quanta knows which chapter you have open and which circuit is on the grid, so "why is this state entangled?" gets an answer about your circuit. Explanations adapt across beginner, intermediate and expert.

The loop

Learn and Build are the same session

The lesson you are reading, the circuit on the grid and the conversation with Quanta all share one workspace. Nothing has to be re-explained when you switch tabs.

  1. Read a chapterOpen Learn and work through the lesson and its interactive visual.
  2. Build it in the editor"Try This In Code" loads the matching circuit into the workspace with the lesson still in context.
  3. Run it and read the resultThe browser simulator recomputes the statevector and redraws the histogram and Bloch sphere.
  4. Ask Quanta what happenedQuanta answers against the chapter you are on and the circuit you just ran.

What comes with every plan

Browser statevector simulator
Exact amplitudes up to 14 qubits, computed locally. Simulation only — TalkinQuantum has no quantum hardware.
Editable Qiskit Python
The circuit you build generates Qiskit code in the editor, and you can download it as a .py file.
Live histogram and Bloch sphere
Outcome probabilities and the q[0] state vector redraw as you edit the circuit.
Shareable circuit links
Copy a link that reopens your exact circuit for anyone who has it.
