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 result

In the workspace, Quanta is given the gates on your grid in the order they run, the code on your screen and the outcomes of your last run — so "why do my qubits always agree?" gets an answer about the circuit and the result in front of you. In Learn it is given the lesson you have open. 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 your conversation with Quanta live in one workspace, and the conversation stays with you 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 and names the lesson you came from.
  3. Run it and read the resultThe browser simulator recomputes the statevector and redraws the histogram and Bloch sphere.
  4. Ask Quanta what happenedQuanta is given the gates in your circuit, in the order they run, and the outcomes of that run — and explains the result at your level.

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.
