A reconfigurable spin ice Spin ices, magnetic systems in which local spins respect the so-called rules, can occur natural materials or be engineered patterned arrays. King et al . used superconducting qubits to implement a two-dimensional artificial ice. By changing strength and ratio of couplings, researchers were able access variety ground states. Arranging boundary an antiferromagnetic configuration then flipping one those generated monopole system’s interior. —JS
