Modelling of q-deformed harmonic oscilator on quantum computer

Abstract

We present a method of a quantum simulation of a quantum harmonic oscillator in a special case of the deformed commutation relation, which corresponds to the so-called q-deformed oscillator on an IBM quantum computer. Using the method of detection of energy levels of a spin system on a quantum computer by probe spin evolution we obtain the energy levels of both the q-deformed quantum harmonic and anharmonic oscillators.
