What is the difference between observation and measurement in reference to a quantum experiment?

Nothing; these words are used interchangeably in QM.

Probably the same as above until someone in a deadlock design a discrepancy ad hoc embedded in an operational definition that leads to an experimental breakthrough in QM.
 
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!
