The Rabi Model is a theoretical framework used in quantum mechanics to describe the interaction between a two-level quantum system, such as an atom, and an external electromagnetic field. It illustrates how the energy levels of the system can oscillate between two states when exposed to a resonant frequency, leading to phenomena like Rabi oscillations. This model is significant in fields like quantum optics and quantum computing, as it helps researchers understand and manipulate quantum states. By analyzing the Rabi frequency, scientists can gain insights into the dynamics of quantum systems and improve technologies like quantum bits or qubits.
