      Abstract: Author(s): Harold M. McNamara, Hongkang Zhang, Christopher A. Werley, and Adam E. Cohen

      Abstract: Author(s): C. Altimiras, F. Portier, and P. Joyez
      In quantum circuits, electrical fluctuations render the behavior of the components interdependent, calling for new circuit rules. Now, researchers establish such rules for simple quantum components.

      Abstract: Author(s): Ziming Zhu, Georg W. Winkler, QuanSheng Wu, Ju Li, and Alexey A. Soluyanov
      Quasiparticles with no direct analogs in the standard model have been recently revealed in experiments. Researchers theoretically analyze the physical properties of triple point fermions, which can be thought of as a melding of Dirac and Weyl fermions.

      Abstract: Author(s): Jiasen Jin, Alberto Biella, Oscar Viyuela, Leonardo Mazza, Jonathan Keeling, Rosario Fazio, and Davide Rossini

      Abstract: Author(s): Vasil S. Denchev, Sergio Boixo, Sergei V. Isakov, Nan Ding, Ryan Babbush, Vadim Smelyanskiy, John Martinis, and Hartmut Neven
      Quantum annealing is a quantum enhanced heuristic optimization algorithm that exploits quantum tunneling. New work shows that it can significantly outperform its classical analog (simulated annealing) as well as the most popular classical algorithm for simulating quantum annealing (quantum Monte Carlo).

      Abstract: Author(s): Chunjing Jia, Krzysztof Wohlfeld, Yao Wang, Brian Moritz, and Thomas P. Devereaux
      X-ray photons can be used as unique probes to understand the properties of elementary excitations. A theoretical study demonstrates that a complex x-ray scattering technique captures richer spectral information than simpler two-particle correlation functions in cuprate superconductors.
