Quantum comptuer is impractical. ← 6/13/2024
(Fig.1) Quantum computer = Parallel worlds = fantasy.
Despite all the media and top universities trying to spread it, quantum computer based on parallel world is unreal, NOT science.
Through this US presidential election, people all over the world lost trust in the mainstream media and its fake news, science (= ex. quantum computer )
Researches on quantum computer have made NO progress, contrary to the media-hype. These pseudo-science is just a tool to extort people's money and tax.
(Fig.2) Quantum computer bit is easily broken within 100 microseconds !
In this Science, they use fictitious quasi-particle in superconducting quantum circuits. Using unreal particles means quantum computer is also unreal.
In this type of quantum computer bit, each electron pair goes back (= 0 ) and forth (= 1 ) through thin insulator called Josephson junction.
This quantum bit is easily broken within very short time ( ~ 100 μs ), which is the reason why quantum computer is impractical forever.
(Fig.3) "Electron pair exist or nonexist" is unknown → parallel worlds ?
In the present theory, they believe "electron pair" called "Cooper" is moving inside superconductor. But this Cooper pair is just a pseudo-state.
Because two electrons cannot attract each other without positive nuclei. By adjusting the voltage, they control the number of electron pair in some area.
Under some voltage, whether the electron pair exits (= 1 ) or nonexists (= 0 ) is unknown between capacitor and insulator.
They misinterpret this "unknown state" as superposition where alive and dead cats coexist at the same time.
So they believe the unreal state where the electron pair exists in one world and it non-exists in another parallel world inside quantum computer bit ← nonsense !
(Fig.4) An electron is a meaningless "letter" in quantum mechanics !
Suprisingly, the present quantum mechanics can show only "nonphysical letters (= c†, c )" as actual electrons. That's all it can do, so useless.
The is the reason the quantum mechanics is useless, just pursues "fantasy".
(Fig.5) Quantum mechanics can do only this ↓ in each electron !
Probably almost no ordinary people know the present physics is useless.
All quantum mechanics can do is two simple actions in each particle.
An electron can only be created (= c† ) or annihilated (= c ) by quantum mechanics. That's all ( p.3 )
As you feel, it's impossible to describe actual complicated and dynamical physical phenomena using only these "too simple" actions !
So if physicists try to describe more complicated phenomena, all they can do is fabricate artificial quasiparticle, which doesn't really exist.
(Fig.6) ↓Bogoliubov quasiparticle lacks reality.
In a recent MIT paper, they try to use unreal quasi-particle, which is superposition of electron and hole (= non-electron ) in quantum computer ?
The present superconductor model relies on unreal phonon quasiparticle. This paper (p.2) mentions another Bogoliubov quasiparticle, too.
Relying on "not actual" quasiparticle means the present science stops pursuing the truth ! It hampers all applied science.
Furthermore, this
Bogliubov quasiparticle contradicts normal particle.
This quasiparticle consists of creation and annihilation of electrons ( this p.4 ).
So "create + annihilate = zero" is what this quasiparticle is !
The problem is the current superconductor model stops at old BCS model, forever.
(Fig.7) Electron pair breaks into "fictional" quasi-particles ?
In a recent top journal Science, they try to use fictional quasi-particle in quantum computer, which is the reason quantum computer is "pie-in-the-sky", forever.
They believe the nonsense theory where the electron pair breaks into fictitious "Bogoliubov quasiparticles" due to some external stimuli ( this p.2 )
So they blindly believe that reducing the number of broken quasi-particle leads to stable quantum computer. ← NO experimental grounds !
As long as we rely on "imaginary objects", it's impossible to realize useful computer. We should stop wasting our tax in useless (= harmful ) science !
