Teacher Tip Emphasize that the coin is an analogy. A real qubit is not simply a hidden coin; it follows quantum rules.

Mission Briefing

A normal computer stores information using bits. A bit can only be one of two values:

0off

1on

A quantum computer uses qubits. A qubit can act like 0, 1, or a mixture of both until it is measured.

0 + 1both possibilities

Key Term: Scientists call this unusual state superposition.

The Strange Coin: not measured yet

Before measurement, the qubit has multiple possible outcomes. When you measure it, you see one classical result: 0 or 1.

Result:

Click the button to run the experiment.

Answer the questions below. No special flag format is needed. Type the answer naturally.

1. What type of information does a normal computer use?

2. What type of information does a quantum computer use?

3. What is the name for a qubit being in multiple possibilities at once?

4. What happens when a qubit is measured?
