Heavy fermion quasiparticle with fake mass is useless for any quantum technologies.

Quasiparticle is unreal

(Fig.1)  Useless quantum mechanical research needs fake goal = quantum computer

Useless quantum mechanical fictional heavy quasiparticle model needs fake application = (hopeless) quantum computers.

The 1st, 2nd paragraphs of this hyped news (8/5/2025) say

".. observed "heavy fermions," electrons with dramatically enhanced mass (= impossible ! ), exhibiting quantum entanglement governed by the Planckian time—the fundamental unit of time in quantum mechanics. This discovery opens up exciting possibilities (= still unrealized ) for harnessing this phenomenon in solid-state materials to develop a new type of quantum computer."  ← fake news

"Heavy fermions arise when conduction electrons in a solid interact strongly with localized magnetic electrons, effectively increasing their mass."  ← false, a real electron cannot increase its mass... Cerium-rhodium-tin (CeRhSn)"

Just measuring electric conductivity was wrongly interpreted as a fictional heavy quasiparticle model by useless quantum mechanical research irrelevant to quantum computers.

The actual research paper says nothing about any practical quantum technology nor quantum computers, contrary to the hyped fake news.

↑ This research paper ↓

p.1-abstract says nothing about any practical technologies such as (hopeless) quantum computers, contrary to the above hyped news.

Unreal quasiparticle's heavier mass decreased electric conductivity ?

p.2-right-2nd-paragraph of the same paper says "Figure 3 indicates the obtained ( fictional ) mass enhancement (m*/m0, where m* and m0 are the effective mass of the quasiparticles and the rest mass of an electron, respectively)"
"the effective mass increased with decreasing temperature"

p.2-Fig.1(b) shows optical conductivity (= σ ) decreases at lower temperature (= due to fictional heavier quasiparticle's effective mass m* in Fig.3 in p.3, this-p.6-lower ).

p.4-conclusion remarks says about the (fictional) heavy quasiparticle, and says nothing about any practical use nor quantum computers (= so useless research ), contrary to the above hyped news.

p.5-left-First-principle band calculations-last says
"The results indicate that the LDA+U (= artificially-chosen fictional exchange-correlation energy functional of density functional theory that cannot predict anything, this-p.12 ) calculation cannot explain the experimental σ1(ω) spectra of CeRhSn."  ← Quantum mechanics failed to explain this

↑ So this experiment just measured some electric conductivity (= σ ) responding to external electric field, and imagined fictional heavy quasiparticles with No practical application.
