For centuries, humanity has imagined that the Universe is built from separate objects interacting through forces that travel across space.
Quantum physics challenges the simplest version of that picture.
Entanglement is the phenomenon. Quantum nonlocality describes a key implication of Bell inequality violations: the correlations cannot be explained by local hidden-variable models satisfying the relevant assumptions.
Experiments show that entangled systems can display correlations that no local hidden-variable model satisfying Bell's assumptions can reproduce.
The deeper lesson is that reality may not fit every assumption inherited from everyday experience.

Quantum information is governed by the laws of quantum mechanics.
Entanglement demonstrates that information about a joint system cannot always be understood by considering its parts independently.

Quantum mechanics introduced us to superposition, measurement, and probabilities that differ from classical expectations.
Nonlocality adds another question: how can distant systems display correlations that local hidden-variable models cannot reproduce?

It can be useful to picture quantum systems as nodes in a network of physical relationships.
In quantum information theory, entanglement is a precise property of quantum states that can be quantified and studied.

Some people interpret coincidences, dreams, or feelings of connection as evidence of a hidden link between minds.
Those experiences can feel powerful and personally meaningful.
