no.

you have, among others,

- single particle single slit
- mach-zehnder
- delayed choice quantum eraser
- two-photon interference experiments
- i guess even quantum entanglement
- there are many ways to come up with new experiments/ideas
 
No, it is just the "textbook" example. If you ask me it is not even a good example since people tend to get hung about the nature of photons etc., which is in no way relevant.
 
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!
