Summary:

- Quantum entanglement is a phenomenon where two or more quantum particles become "entangled" and their properties become linked, even if the particles are physically separated.

- This article discusses how quantum entanglement can lead to "strange" or counterintuitive effects, such as particles seemingly communicating with each other faster than the speed of light, which goes against the principles of classical physics.

- The article explains that quantum entanglement is a fundamental aspect of quantum mechanics and has important implications for fields like quantum computing, cryptography, and the study of the nature of reality.
