• Abstract: The tricritical Ising model serves as an example of emergent spacetime supersymmetry, which can arise in condensed matter systems. In this work, we present a variational quantum algorithm to create this tricritical state on a digitized quantum computer. We successfully prepare the state on an IBM quantum device and verify the critical correlations of supercurrents associated with the state. Additionally, we examine how other signatures of supersymmetry, namely universal gap ratios and the central charge, can be probed on quantum devices.
