Rev. A 109, 022207 (2024) – Published 8 February 2024 Conventional quantum Otto engines based on effective-negative-temperature reservoirs rely on an assumption of perfect thermalization. In this study, the authors investigate the impact of non-Markovianity in these engines by terminating strokes before reaching thermal equilibrium, revealing that higher non-Markovianity enhances maximum efficiency but reduces overall performance over an extended period of functioning time. The authors also identify a class of effective-negative-temperature-based necessarily transient quantum Otto engines.     Editors' Suggestion Recycling of a quantum field and optimal states for single-qubit rotations Shanon Vuglar and Julio Gea-Banacloche Phys. Rev. A 109, 022439 (2024) – Published 28 February 2024 The authors introduce a protocol to generate the electromagnetic field state that is optimal for controlling a given qubit rotation. The protocol, based on the interaction of the field with ancilla qubits, allows for field "recycling" and could potentially reduce error rates and improve energy efficiency in quantum computing schemes.     Editors' Suggestion Loss features in ultracold 162Dy gases: Two- versus three-body processes Maxime Lecomte, Alexandre Journeaux, Loan Renaud, Jean Dalibard, and Raphael Lopes Phys. Rev. A 109, 023319 (2024) – Published 14 February 2024 The authors study the low-field loss features in ultracold thermal samples of 162Dy by examining the density and temperature dependence of various loss features. They demonstrate that a majority of loss features are accurately described by a two-body loss rate instead of the commonly assumed three-body rate.       American Physical Society: 1 Physics Ellipse, College Park, MD 20740 ©2024 American Physical Society | All rights reserved   You are receiving this email because you are subscribed to Table of Content alerts.
