How Do Quantum States Manifest In The Classical World?

Education Saturday with Space Time.


This episode of space time is brought to you by the information flowing through an impossibly complex network of quantum entanglement, that just happens to mutually agree that you and I exist inside it. Oh, and Schrodinger’s cat is in here too.

In quantum world things are routinely in multiple states at once – what we call a “superposition” of states. But in the classical world of large scales, things are either this or that. The famous thought experiment is Schrodinger’s cat – in which a cat is in an opaque box with a vial of deadly poison that’s released on the radioactive decay of an atom. Quantum mechanics tells us that the atom’sfunction can be in a superposition of states – simultaneously decayed or not decayed. So is the cat’sfunction also in a superposition of both dead and alive.
