Spekkens Phys. Rev. A 108, 022207 (2023) – Published 10 August 2023 The authors show that a certain wave-particle duality relation is a type of uncertainty relation whose functional form is known to be able to witness the impossibility of a noncontextual model. In this way, they show that the quantum trade-off between path distinguishability and fringe visibility can witness contextuality and they discuss the requirements on an interferometric experiment necessary for achieving a noise-robust test.     Editors' Suggestion Reducing Rydberg-state dc polarizability by microwave dressing J. C. Bohorquez, R. Chinnarasu, J. Isaacs, D. Booth, M. Beck, R. McDermott, and M. Saffman Phys. Rev. A 108, 022805 (2023) – Published 9 August 2023 The authors demonstrate a reduction of the dc polarizability of cesium atom Rydberg states in a 77-K environment utilizing microwave field dressing. The results could be useful for stabilizing Rydberg resonances against varying dc fields present near surfaces and potentially enabling the development of hybrid Rydberg-atom–superconducting-resonator quantum gates.     Editors' Suggestion Microwave spectroscopy of low-l singlet strontium Rydberg states at intermediate n, 50≲n≲70 R. A. Brienza, Y. Lu, C. Wang, S. K. Kanungo, T. C. Killian, F. B. Dunning, J. Burgdörfer, and S. Yoshida Phys. Rev. A 108, 022815 (2023) – Published 28 August 2023 The authors use microwave spectroscopy to measure the quantum defects for lower-l singlet strontium Rydberg states at intermediate n. The results are used to develop a revised set of Rydberg-Ritz quantum defect parameters that could help make accurate predictions of the energy intervals between other high-lying states.     Editors' Suggestion Measurement of non-Abelian gauge fields using multiloop amplification Qing-Xian Lv, Hong-Zhi Liu, Yan-Xiong Du, Lin-Qing Chen, Meng Wang, Jia-Hao Liang, Zhao-Xin Fu, Zi-Yuan Chen, Hui Yan, and Shi-Liang Zhu Phys. Rev. A 108, 023316 (2023) – Published 28 August 2023 The authors propose a scheme to measure the non-Abelian gauge field through multiloop evolution and robust holonomic quantum gates, and experimentally demonstrate it in the degenerate eigensubspace of a double-Λ four-level atomic system of 87Rb. The results could be useful for the development of high-resolution and high-precision measurements of the gauge fields.     Editors' Suggestion Sub-μm axial precision depth imaging with entangled two-color Hong-Ou-Mandel microscopy Cyril Torre, Alex McMillan, Jorge Monroy-Ruz, and Jonathan C. F. Matthews Phys. Rev. A 108, 023726 (2023) – Published 24 August 2023 Using two entangled photons of different colors in a Hong-Ou-Mandel interference scheme, the authors show that they can precisely measure the thickness of a semitransparent sample. The depth sensitivity is adjustable and the method is resilient against fluctuations commonly encountered in biological samples.       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.
