Time reversal protocols possible one of which is implemented in a dipolar interacting, isolated many-body spin system represented by Rydberg states in an atomic gas. Our time reversal protocol can be used in measurement of Out-of-time-order correlators since time reversal is essential for an OTOC which requires backward evolution of a system which can then be used to measure the extent of information scrambling in the system. However, the dipole-dipole interaction Hamiltonian yields certain second order, perturbative interaction terms which effect the efficiency of our protocol and the fidelity of our measurement. Our goal is to experimentally realize pre-existing theoretical models like a 1-D spin chain to better understand the effect these terms have on our time reversal protocol.
