Difference between bounded and unbounded states in quantum mechanics
Answers
Answer:
In a bound state particles continuously interact with each other, attract each other, and that keeps them together (or in some cases some external force they interact with keeps them together). Like electron and proton in a hydrogen atom. Or a few protons and neutrons in a larger atom nucleus.
In entangled state particles don’t have to keep interacting and don’t have to stay together. You can have two entangled particles 100 km apart. They are called entangled when their quantum states are not independent, they are described together as a single state, a wave function not decomposable into a product of wave functions of two separate particles. So when we describe just one of them, it’s not a pure quantum state but a mixed one.
