Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

https://smallwhale.org/articles/quantum-entanglement

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key theoretical development?Bell's Theorem (1964) and experimental verification (Aspect, Clauser, Zeilinger)
2. What is the enabling technologies?Quantum computing, quantum cryptography, quantum teleportation
3. Why do scientists call it "spooky action at a distance"?Because it seems like one particle can affect another faster than light, which feels mysterious.
4. Can entanglement send messages faster than light?No. You still need regular communication to understand the results, so it doesn't let us send instant messages.

Non-locality: The ability of entangled particles to influence each other instantaneously, regardless of distance.
Decoherence: The loss of quantum coherence in a system due to interaction with its environment.
Qubit: A quantum bit, the basic unit of quantum information, capable of being in superposition.
