Description
Our time-reversal protocol is implemented in a dipolar interacting, isolated many-body spin system represented by Rydberg states in an atomic gas. This protocol can be used in measurement of out-of-time-order correlators (OTOCs) 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.
