Quantum Optics
A creation operator is a mathematical tool used in quantum mechanics that adds a quantum of energy or excitation to a particular state of a quantum system, such as a mode of the electromagnetic field. This operator plays a crucial role in defining and manipulating the quantum states of particles, particularly in contexts where the quantization of fields is essential, such as in squeezed and thermal states. By working in tandem with annihilation operators, creation operators enable the exploration of various physical phenomena within quantum optics.
