Abstract: The quantum states of a harmonic oscillator behave differently in different reference frames. The ground state of the harmonic oscillator in a harmonic vibrating reference frame is the coherent state of the harmonic oscillator in an inertial reference frame.

Key words: inertial reference frame, harmonic vibrating reference frame, harmonic oscillator, ground state, coherent state
