  • Quantum Annealing Simulation of Out-of-Equilibrium Magnetization in a Spin-Chain Compound

    Author(s): Andrew D. King, Cristian D. Batista, Jack Raymond, Trevor Lanting, Isil Ozfidan, Gabriel Poulin-Lamarre, Hao Zhang, and Mohammad H. Amin A quantum annealing processor is used to investigate frustrated magnetism and show how the tuning of quantum fluctuations effect dynamical and equilibrium properties.

  • Entanglement Negativity at Measurement-Induced Criticality

    Author(s): Shengqi Sang, Yaodong Li, Tianci Zhou, Xiao Chen, Timothy H. Hsieh, and Matthew P.A. Fisher Universal multipartite entanglement is studied for a variety of measurement induced phase transitions, exact results are presented in a special case, and remarkable consistency is found in several different models away from this limit.
