(Fig.1) ↓ They just "mixed" classical lights, and call it parallel worlds.
Quantum mechanics with parallel worlds is unrealistic.
The current physics believes a single cat can be dead and alive (= superposition ) at the same time using fictional parallel worlds, but it can never be observed.
They just mixed two classical states or rapidly change states, and call it "superposition", which has nothing to do with quantum parallel worlds.
In this experiment, they just mixed two classical lights with different phases or polarizations, call it a dead and alive cat ( this p.1 ).
What is this "fake" quantum parallel worlds useful for ?
This news just vaguely says "that can in the future be used for quantum communication ?" ← still useless, nothing realized.
In this way, useless quantum mechanics exploits "imaginary future target" to deceive taxpayers and governments.
(Fig.2) ↓ This experiment just measured magnetism ( Not spin ! )
Faster-than-light electron spinning is unreal, which cannot be observed directly.
All we can measure is magnetic field of spin, which accidentally agrees with Bohr magneton caused by electron's orbital motion.
This news is just theory, Not experiment. They use Heisenberg model to describe spin, which is old and useless, just putting three nonphysical letters ( this p.14 )
This news is also just "theory", Not experiment. They use old useless spin model with freely-adjustable parameters ( this p.7, 9 ).
What is this unreal electron spin useful for ?
The last of this news just vaguely says "In the future, become key technologies ?" ← still useless, nothing realized.
This news just says "discover new quantum spin liquid ?", and says nothing about practical use.
They use unreal quantum model with fictitious quasiparticles, which is why quantum mechanics is useless forever.
