Binder, and Sai Vinjanampathy Phys. Rev. A 108, 062214 (2023) – Published 15 December 2023 The authors introduce quantum thermal machines with feedback controlled by nonideal measurements. They shed light on overcoming a fundamental thermodynamic limitation against ideal projective measurements, by demonstrating that nonideal measurements can still drive engines consuming thermal or nonclassical correlations, albeit without additional thermodynamic benefit of quantum over classical correlations.     Editors' Suggestion Fault-tolerant qubit encoding using a spin-7/2 qudit Sumin Lim, Junjie Liu, and Arzhang Ardavan Phys. Rev. A 108, 062403 (2023) – Published 4 December 2023 The authors propose a quantum memory, implemented on a spin-7/2 nucleus coupled to an electron spin-1/2 qubit, which provides X, Y, and Z error correction using fewer quantum resources than the equivalently effective qubit-based protocols.     Editors' Suggestion Monte Carlo graph search for quantum circuit optimization Bodo Rosenhahn and Tobias J. Osborne Phys. Rev. A 108, 062615 (2023) – Published 19 December 2023 The authors introduce a search algorithm aimed at optimizing the arrangement of quantum gates, leveraging different sampling techniques to dynamically grow a graph that represents potential quantum circuits. They demonstrate efficacy in reducing the quantum gate count, both theoretically and numerically, albeit with acknowledged computational challenges as the graph expands.     Editors' Suggestion Theory of hydrodynamic phenomena in optical mesh lattices Hannah M. Price, Martin Wimmer, Monika Monika, Ulf Peschel, and Iacopo Carusotto Phys. Rev. A 108, 063517 (2023) – Published 26 December 2023 The authors develop a theoretical description of superfluidlike phenomena in an optical mesh lattice, a system composed of two fiber loops coupled via a beam splitter. The results provide analytical and numerical interpretation of previous experimental observations and predict physical effects stemming from the spatiotemporally periodic geometry.     Editors' Suggestion Letter Quantum gas microscopy of fermionic triangular-lattice Mott insulators Jirayu Mongkolkiattichai, Liyu Liu, Davis Garwood, Jin Yang, and Peter Schauss Phys. Rev. A 108, L061301 (2023) – Published 13 December 2023 The authors probe fermionic Mott insulators in a geometrically frustrated symmetric triangular lattice using a quantum gas microscope with single-site resolution. They demonstrate the detection of antiferromagnetic spin-spin correlations and perform thermometry by comparison to numerical calculations.       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.
