CHALLENGE #9: THE ENTANGLEMENT CHAIN ⛓️
CNOTs are powerful! They copy correlation, not state. Chaining them spreads one qubit's randomness across many wires, creating a unique kind of entanglement.
Task:
Put ONE H on qubit 0, then chain CNOTs 0→1, 1→2. Predict the histogram, then run it.
Easy mode:
Observe: only 000 and 111 appear. One random choice, three agreeing qubits.
Stretch:
Break the chain: move the H to qubit 1 instead (middle of the chain) and explain the new histogram.
Build it in the Quantum Quest simulator and share your result with the 📸 Community button.
