Hi Guys

For all people interested in Schrodinger's Cat check out Leonard Susskind's explanation - very lucidly explained:
http://www.newpackettech.com/Resources/Susskind/PHY30/LectureRv9_Video_Lec7.htm

The cat is most definitely not in a superposition - it is entangled with the other parts of the apparatus and that entanglement is such the cat is alive or dead - never in a superposition. Open the box - that doesn't change the state of the cat - all that happens is you become entangled with it.

Thanks
Bill

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!
