Coherent states in quantum mechanics bridge the gap between quantum and classical physics, offering insights into the quantum harmonic oscillator. These states minimize uncertainty and are pivotal in quantum computing and optics. They are defined by a Poissonian distribution in superposition of energy eigenstates and are eigenstates of the annihilation operator. Their applications extend to quantum field theory, representation theory, and technologies like lasers and quantum teleportation.
