Case Study
KID Museum Quantum Booth
We were invited by the Bethesda KID Museum to host a quantum learning booth at the KID Expo. We set up a 3-step booth: quantum key distribution, basics of quantum, and quantum algorithms.
Activities
The booth was structured as three stations, each teaching a different facet of quantum computing through play.
Quantum Key Distribution
A fun, all-ages demo. Two participants entangle their Qubis and stand back-to-back. They each shake to measure — getting “up” or “down” — and write their result as 0 or 1. After three rounds, they look up the animal their secret code maps to and shout out the answer.
Learning outcomes
- How do we get information out of entangled qubits?
- How can we share a secret codeword using entangled qubits?
Quantum Circuits
Kids were given a circuit to perform on their Qubis using hand motions — they treated it as a puzzle. Then they played Qubi Hero, a game where they have to perform the correct gates to get a high score.
Learning outcomes
- What is it like to program a quantum computer?
Basics of Quantum
A guided walkthrough of the core operations of a quantum computer: gates, measurements, and entanglement. What stood out most was how engrossed the kids were — they stayed focused and asked questions throughout.
Learning outcomes
- What is a qubit in real life?
- What is a gate? How is it performed?
- What does it mean to not measure a quantum computation?
What kids learned
Even the youngest participants walked away with real intuition for quantum ideas — built through play, not lecture.
What a qubit is
A qubit is different from a regular bit — it can be in a mix of states until you look at it
Measurement changes things
When you shake a Qubi to measure it, it picks a result — you can’t know the answer in advance
Quantum gates
You can change a qubit’s state with specific hand motions, just like programming a quantum computer
Entanglement is real
Two Qubis can be linked so that measuring one instantly tells you about the other
Secret codes from quantum
Entangled measurements can create shared secrets — the basis of quantum key distribution
Quantum circuits as puzzles
A sequence of gates is like a recipe — kids solved circuit puzzles by performing the right moves in order

Kids of all ages were captivated by the hands-on quantum experience.
