Bringing quantum to your hands

A qubit you can hold.

Learn quantum gates with your hands, not a screen.

Blochy is a glowing Bloch sphere with real quantum gate buttons. Press the buttons and watch the qubit’s state travel across the sphere in light. No phone and no app.

Try the BLOCHY Challenge

Reach the amber light in as few gates as you can.

X, Y and Z are half turns. S is a quarter turn and T an eighth turn around the vertical axis. H swaps |0⟩ with |+⟩. Once you’ve pressed a gate, the H X Y Z S T keys work too.

Par 3 · press a gate to start

On Blochy these are physical buttons, and the path lights up in LEDs.

The problem

The qubit is still taught on a flat page

The Bloch sphere is the mental model behind every quantum gate, and it is 3D. Textbooks and screens flatten it, so cause and effect never click.

Industry talks qubits…
Students drown in jargon…
Teachers struggle to show it…
…until it’s in their hands.

How it works

Every quantum state is a destination. Every operation is a flight.

Think of the sphere as a globe. Every point on it is a quantum state, and every gate is a flight that carries the qubit somewhere new. Reach the target in the fewest flights and you’ve beaten the BLOCHY Challenge.
