Physics
Time Evolution of Quantum States
Quick fact
The time evolution of a quantum state is governed by the Schrödinger equation, which tells us how the probabilities of finding a particle in different states change as time passes.
Why this is interesting
Imagine a spinning coin that never lands—just keeps flipping between heads and tails in perfect balance. In quantum mechanics, particles behave similarly, but instead of flipping, they evolve over time in ways we can’t predict with classical physics.
