Jackson Kimball, Dmitry Budker, Timothy E. Chupp, Andrew A. Geraci, Shimon Kolkowitz, Jaideep T. Singh, and Alexander O. Sushkov Phys. Rev. A 108, 010101 (2023) – Published 17 July 2023 Advances in spin-based quantum sensors are opening new frontiers in precision "table-top" tests of fundamental physics, complementary to the approaches pursued in high-energy experiments.     LETTERS Advancing hybrid quantum-classical algorithms via mean operators Donggyu Kim, Pureum Noh, Hyun-Yong Lee, and Eun-Gook Moon Phys. Rev. A 108, L010401 (2023) – Published 24 July 2023 The authors propose a protocol that combines the advantages of hybrid algorithms and the standard mean-field theory in condensed matter physics. They demonstrate that the protocol can reduce the number of quantum operations for preparing an entangled many-body state by introducing a mean operator.     Quantum acoustic Fano interference of surface phonons J. M. Kitzman, J. R. Lane, C. Undershute, N. R. Beysengulov, C. A. Mikolas, K. W. Murch, and J. Pollanen Phys. Rev. A 108, L010601 (2023) – Published 18 July 2023 The authors demonstrate the interference of surface acoustic wave phonons in a hybrid quantum acoustic device via spectroscopic measurements of a coupled superconducting qubit. The results reveal the interaction between confined and continuum phonon modes and highlight the importance of phononic interference in emerging quantum information systems based on circuit quantum acoustodynamic (cQAD) architectures.     Conductance transition with interacting bosons in an Aharonov-Bohm cage A. R. Kolovsky, P. S. Muraev, and S. Flach Phys. Rev. A 108, L010201 (2023) – Published 11 July 2023 The authors study transport of interacting bosons through an Aharonov-Bohm cage - a building block of flat-band networks - with coherent pump and sink leads. By simultaneously employing mean-field, pseudoclassical, and genuine quantum approaches they identify different transport regimes through the cage, ranging from fully insulating to fully conducting regimes.       American Physical Society: 1 Physics Ellipse, College Park, MD 20740 ©2023 American Physical Society | All rights reserved   You are receiving this email because you are subscribed to Table of Content alerts.
