What is quantum entanglement?
0:02
Definition: Quantum entanglement is a
0:04
phenomenon in which two or more
0:06
particles become linked in such a way
0:09
that the state of one particle instantly
0:11
affects the state of the other, no
0:13
matter how far apart they are.

Explanation: When particles interact and
0:18
become entangled, their quantum states
0:20
can no longer be described
0:24
Instead, they share a single combined
0:26
wave function. Measuring one particle's
0:28
property like spin, polarization, or
0:31
momentum immediately determines the
0:33
outcome for the other, even across vast
0:36
distances. This spooky action at a
0:38
distance, as Einstein called it, does
0:41
not transmit energy faster than light,
0:43
but shows that quantum mechanics defies
0:46
classical separability. Entanglement is
0:49
at the heart of modern quantum
