Rabi Oscillations

Rabi oscillations describe the process where a quantum system, such as an atom or quantum bit (qubit), transitions back and forth between two energy states when driven by a resonant electromagnetic field. Imagine pushing someone on a swing: with each push (energy input), they swing higher or lower, alternating continuously if timed correctly. In quantum terms, the system's probability of being in one state or the other oscillates over time, showing a predictable, controlled pattern of state changes. This phenomenon is fundamental in quantum control and is crucial for technologies like quantum computing and precision measurements.
