| contents | Using programmable analog quantum annealing processors, we implement a sampling-based magnetic hysteresis protocol to probe the counterintuitive notion of magnetic memory of antiferromagnets. A key component of this protocol responsible for the hysteresis is a transverse field, which enables state transitions, while the magnetic field sweep is done via a longitudinal control field. We present evidence of full saturation and reversal of the hysteresis curve, as well as emergent magnetic domain mediated by quantum fluctuations that give rise to the magnetic memory effect in antiferromagnets. |
