Rabi Oscillation refers to the phenomenon where a quantum system, such as an atom or a particle, oscillates between two energy states when subjected to an external electromagnetic field. This oscillation occurs at a specific frequency, known as the Rabi frequency, which depends on the strength of the external field and the properties of the quantum system. In practical terms, Rabi oscillations are crucial in fields like quantum computing and atomic physics. They enable precise control over quantum states, allowing scientists to manipulate and measure quantum systems effectively. Understanding Rabi oscillations helps in developing technologies like quantum bits or qubits, which are fundamental for quantum information processing.
