(Fig.1) ↓ Light escapes black hole = sound wave escapes atom ?
Hawking radiation is "imaginary" concept that a pair of virtual particles may evaporate black hole ?
First, clock time stops near black hole, so outside observer on the earth can never see this Hawking radiation or black hole formation, so meaningless research.
Though this black hole research is waste of time, the current physicists try to generate its "analogue" (= fake Hawking radiation ) in lab.
They treat water, sound wave, light as "fake" Hawking radiation from artificial black hole. ← nonsense.
In above figure, when atoms move faster than sound wave, the sound wave cannot escape from the atoms, which "resembles" Hawking radiation where the light cannot escpape black hole ?
In this experiment, they changed some light speed, and said "some light cannot overtake other lights, this is black hole analogue !" ← nonsense.
So-called "AI" is useless science to mislead taxpayers, used just to simulate fictional black hole or BigBang.
It's about time we stopped wasting time and money in "imaginary" science.
(Fig.2) Mixed lights = "superposition" = parallel worlds ? 
Quantum mechanics is crazy.
Just when two lights with different polarizations are mixed, they call it "superposition" = a dead and alive cat in parallel worlds.
When this light is very weak, they call it "photon", which is just electromagnetic wave.
They try to use this weak light (= photon ? ) as "imaginary" target = future quantum computation and communication ? ← still useless, nothing realized.
Photon is just weak, "fragile" light, so if someone tries to intercept it, the light is easily broken. They start to say "it can be used to detect eavesdropping as quantum cryptography !" ← nonsense.
"Fragile" weak light (= photon ) means it cannot be used as long-distance communication, so useless.
This is just an imaginary theory ( Not experiment ) mixing quantum parallel worlds (= superposition ) with Einstein relativity.
(Fig.3) ↓ Quantum mechanics lacks reality.
This introduction says they use fictitious quasiparticle with fake mass and charge as spintronics.
Their "spin" means just "magnetic interaction" of cold atoms, which is Not real spinning, but just electron's orbit.
What is this unreal electron's "spinning" useful for ?
This news just vaguely says "potentially paving the way for spintronics ?" ← still useless, nothing realized.
As shown in this methods, this research is full of unreal concepts such as quasi-momentum, pseudo-spin ?
