A system of bosons can be modeled as a system of harmonic oscillators, a phenomenon that occurs everywhere in nature. The motion of a spring bobbing up and down and the vibration of a plucked string are both examples of harmonic oscillators. In quantum mechanics, the harmonic oscillator motion is described by
typical wave functions.
Several (typical) wave functions are shown here. A Fermilab team recently found a way to represent wave functions for bosonic systems on a quantum computer. Image: Allen McC
