RADIATIVE PROCESS ON A QUANTUM COMPUTER

We propose a method to compute radiative processes using a quantum computer. Transition between initial and final states during the capture process in a small box leads to Rabi oscillations. The amplitude and frequency of these oscillations are shown to be related to the transition matrix elements. This algorithm is demonstrated by calculating the E1 transition rate between ground and excited states of a particle in a harmonic oscillator potential using a quantum simulator.
