To address this, we have been improving access via several different mechanisms. See Off-Campus Access to Physical Review for further instructions. APS and the Physical Review Editorial Office Continues to Support Researchers COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access. We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. And we hope you, and your loved ones, are staying safe and healthy. Introducing PRX Quantum , a new Physical Review journal Opening for submissions mid-2020, PRX Quantum will be a highly selective, open access journal featuring quantum information science and technology research with an emphasis on lasting and profound impact. The journal expands on the excellence and innovation of Physical Review X (PRX). 50 th Anniversary Milestones The collection contains papers that have made important contributions to atomic, molecular, and optical physics and quantum information by announcing significant discoveries or by initiating new areas of research. Collection EDITORS' SUGGESTION Quantum error-correction codes and absolutely maximally entangled states The connection between maximally entangled states and quantum error-correcting code is explored to gain insight on the AdS-CFT correspondence, i.e., on the link between gravity and quantum field theories. The study presents corrections to the so-called Ryu-Takayanagi formula. Paweł Mazurek et al. Phys. Rev. A 101 , 042305 (2020) EDITORS' SUGGESTION Near-term performance of quantum repeaters with imperfect ensemble-based quantum memories Four different quantum repeater schemes built with ensemble-based quantum memories are analyzed in order to guide experimentalists to achieve real-world implementations. The work focuses on repeaters devoid of error correction and suggests that meaningful proof-of-principle demonstrations are within reach of current technology. Yufeng Wu, Jianlong Liu, and Christoph Simon Phys. Rev. A 101 , 042301 (2020) MILESTONE Orbital angular momentum of light and the transformation of Laguerre-Gaussian laser modes The orbital angular momentum of light debuts as a versatile tool, enabling several applications. L. Allen, M. W. Beijersbergen, R. J. C. Spreeuw, and J. P. Woerdman Phys. Rev. A 45 , 8185 (1992) Collection EDITORS' SUGGESTION Verifying multipartite entangled Greenberger-Horne-Zeilinger states via multiple quantum coherences An 18-qubit GHZ state with multipartite entanglement is prepared and measured on a 20-qubit device. The detection technique used, which is based on measuring multiple quantum coherences, is robust to noise and only requires measuring the population in the ground state. Ken X. Wei et al. Phys. Rev. A 101 , 032343 (2020) EDITORS' SUGGESTION Cooper minimum of high-order harmonic spectra from an MgO crystal in an ultrashort laser pulse The crystal harmonic spectra of MgO from an ultrashort midinfrared laser pulse are shown to exhibit the Cooper minimum characteristic. This study could potentially be useful for retrieving the band information of solid materials and all-optical reconstruction of the band structure through high-order harmonic generation. Yiting Zhao et al. Phys. Rev. A 101 , 033413 (2020) MILESTONE Computable measure of entanglement An effective quantifier of entanglement is introduced. G. Vidal and R. F. Werner Phys. Rev. A 65 , 032314 (2002) Collection NEWS AND COMMENTARY A More Precise Atom Interferometer March 12, 2020 A method that increases the precision of atom interferometers could lead to improved force and energy measurements for testing physics beyond the standard model. Synopsis on: Katherine E. McAlpine, Daniel Gochnauer, and Subhadeep Gupta Phys. Rev.

A 101 , 023402 (2020) More Kaleidoscopes EDITORS' SUGGESTION Circuit-centric quantum classifiers A machine learning design is developed to train a quantum circuit specialized in solving a classification problem. In addition to discussing the training method and effect of noise, it is shown that the circuits perform reasonably well on classical benchmarks. Maria Schuld, Alex Bocharov, Krysta M. Svore, and Nathan Wiebe Phys. Rev. A 101 , 032308 (2020) FEATURED IN PHYSICS 50 Years of : The Legacy of Three Classics Physicists working in optics, atomic and molecular physics, and quantum information reflect on landmark papers and how they influence research today. Special Feature in Physics EDITORS' SUGGESTION Superradiant optomechanical phases of cold atomic gases in optical resonators Superradiant emission of light from a cold atomic gas in an optical resonator is analyzed theoretically. It is shown that the dynamics ofsuperradiant emission is accompanied by the formation of spatialstructures. Three different phases, incoherent, coherent, and chaotic,are identified where the coherence properties are distinctly different. Simon B. Jäger, Murray J. Holland, and Giovanna Morigi Phys. Rev. A 101 , 023616 (2020) MILESTONE Theory of high-harmonic generation by low-frequency laser fields The authors develop one of the most popular models of high-harmonic generation. M. Lewenstein et al . Phys. Rev. A 49 , 2117 (1994) Collection EDITORS' SUGGESTION Excited-band Bloch oscillations for precision atom interferometry A method based on Bloch oscillation in an excited band of a pulsed optical standing-wave lattice to increase the momentum separation between the arms of an atom interferometer is proposed and demonstrated experimentally. A significant improvement in measurement precision is achieved. Katherine E. McAlpine, Daniel Gochnauer, and Subhadeep Gupta Phys. Rev.
