Understanding Quantum Entanglement
The gist
Quantum entanglement is a phenomenon where two or more particles become linked so that the state of one instantly influences the state of the other, no matter the distance between them.
Explain like I'm 5
Imagine you have two magic coins that always show the same side when flipped, even if one is on Earth and the other is on the Moon; that's like quantum entanglement.
Big picture
Quantum entanglement challenges our usual ideas about how things should behave and is key to developing new technologies like quantum computers and secure communication.
