Coherent quantum states

Coherent quantum states are special states of a quantum system, like light or atoms, that behave in a way closest to classical physics. They resemble classical waves, with well-defined amplitude and phase, and exhibit minimal quantum uncertainty. Think of them as the quantum equivalent of a smooth, steady wave in the ocean, rather than a chaotic splash. Coherent states are important because they help us understand how quantum systems can mimic classical behavior, and they are fundamental in technologies like lasers, where they produce intense, stable beams of light.
