Mission Complete  Summary and Q&A
TL;DR
Can spies come up with predetermined answers without communicating? The answer lies in entangled particles and Bell's Theorem.
Questions & Answers
Q: Can spies come up with predetermined answers without communicating?
No, because regardless of how they decide their answers, they will always break the rule that teammates only say the same thing half the time.
Q: How can entangled particles be used to solve the puzzle?
By giving each spy an entangled particle, they can measure it differently depending on the question asked, ensuring they give the same answer when asked the same question.
Q: Why is Bell's Theorem important in this solution?
Bell's Theorem shows that entangled particles can affect each other's measurements, even in situations where normal objects cannot communicate.
Q: Why shouldn't the spies use the entangled particle solution?
If the enemy knows the spies used entangled particles, they would realize that the spies were scheming against them.
Summary & Key Takeaways

The video discusses a puzzle about spies who need to answer questions in a specific way without communicating.

Predetermined answers and communication were both found to contradict one of the requirements.

The solution involves using entangled particles and Bell's Theorem to ensure the spies only give the same answer half the time.
