NewQanad Lab is open: build circuits and export to Qiskit, Cirq & OpenQASM

Learn quantum computing from |0⟩
to algorithms on
real qubits.

Start from zero with visual lessons. Build circuits in a lab that writes the code for you. Finish by running it on a real quantum computer.

The path

Zero to hardware in eight levels.

Each level is a run of short, visual lessons that ends with something to build in the Lab. No level assumes more than the one before it.

  • Qubit layouts
  • IBM & AWS
  • Noisy results

Qanad Lab

Build a circuit. Read it in six languages.

Drag gates onto wires and the Lab simulates every change instantly, then writes the code for you. It's the bridge between “I get it” and “I can run it.”

  • One circuit, six languages

    Qiskit, Cirq, OpenQASM 2 & 3, PennyLane and Amazon Braket, side by side and always in sync.

  • Scrub through time

    Step gate by gate and watch amplitudes, probabilities and Bloch spheres change.

  • See entanglement

    Each qubit gets its own Bloch sphere. When the arrow shrinks, that qubit is entangled.

  • Share with a link

    Every circuit fits in a URL. Send it to a friend, a teacher or your future self.

  • Nothing to install

    A full state-vector simulator, up to 16 qubits, right in your browser.

How Qanad teaches

Hard ideas, gentle ramps.

Picture first, symbols second

Every idea shows up as something you can see and poke before it shows up as an equation. The math still comes, but it lands on something you already understand.

Learn by breaking things

Each lesson ends in the Lab with a circuit to change, so you find out what each gate really does.

Honest about the hype

What quantum computers can do today, what they might do soon, and what's still science fiction. We say which is which.

Real hardware, early

Simulators are perfect; real qubits aren't. You'll meet real-device noise long before the final level, because that's where the interesting problems live.

The Qanad Journal

Writing that makes the weird make sense.

Deep, carefully checked explainers on the fundamentals, new research, and where quantum meets machine learning. Every piece links to a circuit you can open in the Lab.

First issues in the works

FundamentalsIssue 01

What is a qubit, really?

Not a tiny coin spinning in the air. A careful, picture-first look at amplitudes, superposition and what measurement actually does.

Coming soon
AlgorithmsIssue 02

Grover's search, one amplitude at a time

Watch a marked answer rise out of the crowd step by step, and see why the speed-up is quadratic rather than magic.

Coming soon
Quantum × MLIssue 03

Quantum machine learning without the hype

Variational circuits, quantum kernels and barren plateaus: where QML shows promise, and where classical methods still win.

Coming soon
HardwareIssue 04

Superconductors, ions, atoms, photons

A field guide to the machines: how each technology makes a qubit, and the trade-offs that come with it.

Coming soon
ResearchIssue 05

Why logical qubits are the milestone to watch

Error correction turns many noisy qubits into one reliable one. How to read the headlines when a lab announces a new record.

Next badge: build Grover's search in the Lab.

Your first qubit is waiting.

Open the Lab, drop a Hadamard on a wire, and watch a certainty turn into a coin flip. It takes about ten seconds.
