Exciton quasiparticle switch is useless, hyped.

Exciton quasiparticle is unreal

Overhyped exciton switch is too bulky, impractical with No memory.

(Fig.1)  Light transiently excites electrons and holes (= fictional exciton quasiparticles ? ), which are too short-lived, useless as a switch.

Fictional exciton quasiparticles are useless, contrary to fake news.

Quantum mechanical researches rely on old fictional uselesss quasiparticle models, which fact is hidden by overhyped fake news.

The 1st paragraph of this overhyped news (9/11/2025) says
"A new optoexcitonic switch already achieves state-of-the-art performance over current electronics and could serve as the basis for classical and quantum computing devices"  ← fake news

An exciton switch is too bulky, short-lived, impractical.

It is impossible to control and store a neutral fictional exciton quasiparticle consisting of a too short-lived excited electron and a hole. = useless for switch, solar cells.

The 1st, 3rd, 5th, 7-8th, 10th, 12-13th paragraphs of this news on the same hyped research say
"A new nanostructure acts like a wire and switch that can, for the first time, control and direct the flow of quantum quasiparticles (= unreal ) called excitons at room temperature."

"Because they have no electrical charge, excitons have the potential (= still unrealized ) to move quantum information without the losses "

"excitons are already commonly used for energy conversion—at work in lights, solar cells and more."  ← fake news

"The negatively charged electron and positively charged hole attract one another and move as a pair, together forming a net neutrally charged exciton."  ← So a fictional exciton quasiparticle is just a transiently excited electron and hole.

"While an exciton's neutral charge enables it to move without losses, it comes with a drawback: it's hard to move excitons deliberately."

"When the electrodes are switched on, the voltage creates an energy barrier that prevents the excitons from moving. When the voltage is switched off, the excitons flow again"

"In addition to creating the excitons by causing the electrons to jump energy levels, the light couples with the excitons and helps to drive them along the ridge."  ← Light is needed to generate and control a neutral exicton

"Together, the ridge structure and light interaction successfully transported excitons in a single direction up to 4 micrometers (= a bulky switch ) in less than half a nanosecond at room temperature (= this-p.6 shows photoluminescence (= PL ) detecting reemitted light was used to indirectly detect and imagine a fictional exciton ).

".. As a next step, the team aims (= still unrealized ) to connect hundreds of excitonic switches."

A fictional short-lived exciton quasiparticle in a useless bulky switch.

Just transiently exciting electrons (= fictional excitons ? ) in a bulky switch with No memory is useless.

↑ So this fictional exciton quasiparticle switch is too bulky (= 4μm = 4000nm compared to today's compact transistor switch of only 40nm,  this-4th-last-paragraph = an exciton cannot be stopped nor confined to a small space, inconveniently ).

↑ And this research just transiently excited a fictional exciton consisting of an electron and a hole (by light ), whose lifetime is too short (= nanosecond ) to store as a memory.  ← Just a bulky switch with No storage memory (= because storing a electorically-neutral exciton is impossible ) is meaningless.

↑ This too bulky, too short-lived exciton switch (= just transiently excited by light with No storing memory ) is completely useless, contrary to the above overhyped fake news.

Actually even this overhyped news (= 2nd-last-paragraph ) also admits
"The ultimate goal is to scale these switches into circuits that would, ostensibly, replace current electronics. According to the researchers, several advances are necessary to reach that goal (= pipe dream )"
