Ok is this article as silly as it seems to me?

When I think of quantum cooling I think of laser cooling. Which is cool. But that's an article that is meant only for devout quantum physicists. I say if something even remotely close to what they want to do is actually shown in a real experiment then I'll first eat my own shoe and second I'll stop making fun of quantum mechanics. I wouldn't count on it though.

P.S. the math seems right though. So it's not silly in that sense.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
