... Let’s assume V(x) = 0 between x=0 and x=L, and is infinite everywhere else…. Then, independent of energy, the electron cannot get out. Classically just bounces to and fro at constant speed, and the probability of being any one position inside (along x) is the same. Quantum mechanics: solve Schroding ...

Reliable and efficient ways of mapping quantum information between light and matter are therefore an essential compone ...
