<s>[INST] This thread is for discussion of potentially game-changing aspects of quantum mechanics that are often misunderstood (and overhyped) on popular science websites.
Quantum weirdness is a real phenomenon used in several applications. However, sorting through all the pedantic discussions centered on what quantum weirdness entails, its relationship to the interpretation of QM, and its potential for "changing the world" can be overwhelming. So, let's focus on one emergent property of quantum mechanics that may be widely misunderstood: quantum entanglement.

**Quantum entanglement**: When observables such as energy or spin (components) are correlated between two or more subsystems, such that the state of one cannot be described independently from its partners, this is called entanglement. For most people, this sounds like a potential applicator of magic that can be harnessed to apply an operation on another particle across the universe

Quantum entanglement is real and is associated with many applications. Yet, most of all claims that you have read on the internet use experimental evidence from EPR (Einstein-Podolsky-Rosen) and Bell's theorem to argue entanglement is non-local. More profoundly, the popular internet is secretive about how researchers still debate the question of whether the entanglement in those experiments is transitively non-local or if local(-ish) explanations exist that are still compatible with existing evidence.

**Two simple questions to narrow the debate and increase twenties** Yes/No answers). If entanglement cannot be used for faster-than-light communication, _what makes entanglement different from plain old classical correlations(bullet points)
