(Fig.1) ↓ Spin is unreal, just energy levels.
Entanglement (= spooky action ?) is unreal, useless science.
Because "entanglement" itself does nothing, it cannot send any real information.
So this experiment in Nature
is meaningless.
Electron spin (= faster-than-light rotation !? ) doesn't exist.
They just call energy levels "up or down spins". Unreal spin itself cannot be seen.
When an atom is in upper energy level (= spin up ? ), it emits light. They mix lights from two nitrogen atoms.
When a photon detector detects "light", it means either one of atoms is in upper energy level, and another atom is in lower energy level. ← entangle ?
They call this state "entanglement" where upper and lower energy levels (= spin up and down ) in two atoms are correlated, entangled ? ← Nonsense.
See this p.2-3
(Fig.2) ↓ Phonon is unreal quasiparticle. 
Quantum mechanis has given up clarifying true microscopic mechanism.
Quantum mechanics just fabricates fictitious unreal quasiparticle with fake mass and charge to explain experimental results, so useless.
They try to explain atomic classical vibration using quasiparticle = phonon, which is Not an actual particle, but just nonphysical symbol.
So quantum mechanics relying on unreal quasiparticles are useless, forever.
See this p.2 right lower.
(Fig.3) ↓ Just complex magnetic pattern. = No practical use.
This research is about skyrmion, which is not real particle, just a fictitious quasiparticle.
Skyrmion is just another name for some vortex-like magnetic pattern. --- still No practical use.
The present condensed matter just pursues unreal quasiparticle with fake charge and mass.
So quantum mechanics is useless, forever.
