Inomata, Y. Nakamura, A. Marx, F. Deppe, R. Gross, and K. G. Fedorov Phys. Rev. A 106, 052415 (2022) – Published 15 November 2022  | The authors experimentally investigate the behavior of quantum discord and entanglement in two-mode squeezed states generated by superconducting Josephson parametric amplifiers. They show how correlations flow between the two modes and the noisy environment, and relate their findings to the security of entanglement-based quantum key distribution. | | | | | | Editors' Suggestion Germain Tobar, Simon Haine, Fabio Costa, and Magdalena Zych Phys. Rev. A 106, 052801 (2022) – Published 1 November 2022  | The authors study quantum effects resulting from mass-energy equivalence using ultracold neutrons that are confined gravitationally by considering a quantum correction to the neutron's mass due to the neutron spin in the presence of an external magnetic field. The authors show that the neutron's additional weight due to the quantum treatment of mass-energy equivalence will cause a small shift in the neutron's eigenenergies and eigenstates, which could provide signatures in an interferometric experiment. | | | | | | Editors' Suggestion Riley A. Stewart, Pinrui Shen, James L. Booth, and Kirk W. Madison Phys. Rev. A 106, 052812 (2022) – Published 30 November 2022  | The authors demonstrate a new method for measuring the C6 van der Waals coefficient of the Rb-Rb interaction potential from the loss rate of atoms confined in a shallow atom trap of tunable depth. The technique is based on the universal nature of the room-temperature collisions, which depends only on the long-range potential between the collision partners. | | | | | | Featured in Physics Editors' Suggestion Robert J. Cooper, David W. Prescott, Karen L. Sauer, Nezih Dural, and Michael V. Romalis Phys. Rev. A 106, 053113 (2022) – Published 23 November 2022  | The authors develop two optically pumped atomic magnetometers with sub-fT sensitivity operating at radio frequencies and compare their magnetic-field sensitivity and interference rejection. They identify ways to improve the sensitivity of unshielded magnetic detectors, which could advance the development of portable magnetometers for field uses. | | | | | | Editors' Suggestion Manel Bosch Aguilera, Alexis Ghermaoui, Rémy Vatré, Raphaël Bouganne, Jérôme Beugnon, and Fabrice Gerbier Phys. Rev. A 106, 053304 (2022) – Published 4 November 2022  | The authors study experimentally the non-Hermitian dynamics and dissipative properties of pairs of two-level atoms tightly confined in an optical lattice and driven by a near-resonant laser towards a lossy state. They demonstrate the control of the quantum state of the pairs in the strong dissipation regime by adiabatically preparing them in a loss-protected state, where the dynamics is governed by the quantum Zeno effect. | | | | | | Editors' Suggestion Heming Wang, Boqiang Shen, Yan Yu, Zhiquan Yuan, Chengying Bao, Warren Jin, Lin Chang, Mark A. Leal, Avi Feshali, Mario Paniccia, John E. Bowers, and Kerry Vahala Phys. Rev. A 106, 053508 (2022) – Published 10 November 2022  | The authors study theoretically and experimentally how Kerr frequency combs can be controlled using self-injection locking. The authors show how self-stabilized switching waves supported by microresonators with normal dispersion and feedback can be used to generate frequency combs more efficiently by tuning the pulse duty cycle into regimes that are difficult to access using other methods. | | | | | | Editors' Suggestion Hsing-Ta Chen, Zeyu Zhou, Maxim Sukharev, Joseph E. Subotnik, and Abraham Nitzan Phys. Rev. A 106, 053703 (2022) – Published 2 November 2022  | Typically, in molecular ensembles, the fast random modulation of transition frequencies is merely considered to result in molecular dephasing. In contrast, the authors here show that such modulation may actually recover collective superradiant emission. | | | | | | Editors' Suggestion Samuel Buckley-Bonanno, Stefan Ostermann, Oriol Rubies-Bigorda, Taylor L. Patti, and Susanne F. Yelin Phys. Rev. A 106, 053706 (2022) – Published 7 November 2022  | Quantum emitter arrays with embedded impurities offer the ability to control interactions between individual photons and quantum matter. Here, the authors investigate the lifetime of optical excitations in such arrays and reveal the importance of placement. | | | | | | | |
