Researchers in Canada demonstrated a large-scale quantum simulation of this phenomenon in a network of 1,800 in situ programmable superconducting niobium flux qubits whose pairwise couplings are arranged in a fully frustrated square-octagonal lattice. They observed the emergence of a complex order parameter with continuous rotational symmetry, and the onset of quasi-long-range order as the system approaches a critical temperature. According to the researchers the approach of using a quantum processor as a programmable magnetic lattice will find widespread use in the simulation and development of exotic materials…read more. TECHNICAL ARTICLE
