See quantum thinking — don’t just read about it.
Quave is a browser-only instrument where you write tiny Qubble programs and watch the amplitudes light up. A qubit holds a blend of possibilities you can actually see; measuring turns a blend into one definite answer.
Made for curious kids (and everyone). Nothing to install, nothing gets uploaded, and every demo is readable Qubble over a handful of built-in gates.
Not ordinary code
This is a quantum instrument, not a code editor
Most “coding” tools show you text and output. Quave shows you the state — the blend of possibilities and their phases — changing as your program runs.
Amplitudes are the hero
Every possibility is a bar of light. Watch them grow and shrink — that is the quantum state itself, not a summary of it.
Interference, made visible
Matching phases add up and opposite phases cancel — like waves of light. That interference, not raw speed, is where any quantum advantage comes from.
Honest by construction
No cloning. No “both 0 and 1 at once.” No faster-than-light messages. The physics is enforced and explained the careful, correct way.
The journey
From your first spin to a shared demo
Write a line of Qubble
Start with q = qubit then spin q. Plain words for real gates.
Watch the amplitudes
Press Run or Step and see the blend of possibilities light up and shift.
Run it many times
Measure and Run ×N to see the distribution — randomness you can trust.
Deploy & share
Publish your demo to the Gallery so anyone can press play and read every line.

Kid-built quantum demos
Each one is a small Qubble program someone built and shared. Press Try it to play it — watch the amplitudes, step through it, or run it many times.
Safe by absence
Everything runs in your browser. There is no network inside a program, nothing is uploaded, and there is no data to leak. Accounts are just a username and password — no email required.
Honest about the physics
We say a qubit holds a blend of possibilities (not “both at once”), that entangled qubits are correlated but can’t send a message, and that a quantum computer helps only some problems. Physics explanations are marked pending physicist review until an expert signs off.
