Kamien Phys. Rev. A 108, 030001 (2023) – Published 25 September 2023   Editors' Suggestion Error mitigation for quantum approximate optimization Anita Weidinger, Glen Bigan Mbeng, and Wolfgang Lechner Phys. Rev. A 108, 032408 (2023) – Published 8 September 2023 Quantum error mitigation involves reducing errors in hybrid quantum-classical algorithms, which is particularly relevant for near-term noisy quantum devices. The authors introduce an error mitigation technique based on redundant parity encoding of logical variables. They demonstrate the use of this technique by applying it to the quantum approximate optimization algorithm.     Editors' Suggestion Optimal single-qubit tomography: Realization of locally optimal measurements on a quantum computer Bacui Li, Lorcán O. Conlon, Ping Koy Lam, and Syed M. Assad Phys. Rev. A 108, 032605 (2023) – Published 13 September 2023 The authors map qubit tomography to a quantum multiparameter estimation problem and find the optimal single-qubit measurements. Using a quantum computing demonstration they show that the optimal separable measurement bound can be saturated.     Editors' Suggestion Simulations of a frequency-chirped magneto-optical trap of MgF Kayla J. Rodriguez, Nickolas H. Pilgram, Daniel S. Barker, Stephen P. Eckel, and Eric B. Norrgard Phys. Rev. A 108, 033105 (2023) – Published 8 September 2023 The authors present a theoretical analysis of a frequency-chirped molecular magneto-optical trap (MOT) that may open the way for efficient cooling of a class of light molecules. They show that this approach can increase the capture velocity of the MOT which could be used to capture more molecules from typical molecular sources and, in some cases, perhaps remove the need for laser slowing before capture in the MOT.     Editors' Suggestion Unavoidability of nonclassicality loss in PT-symmetric systems Jan Peřina, Jr., Adam Miranowicz, Joanna K. Kalaga, and Wiesław Leoński Phys. Rev. A 108, 033512 (2023) – Published 15 September 2023 The authors study the dynamics of two nonlinearly coupled oscillator modes in a PT-symmetric system, in which gain and loss are provided by coupling a pair of bosonic modes to separate baths. The authors show that even when the model parameters are fine-tuned to achieve a balance between gain and loss in the semiclassical limit, the fluctuations of the bath lead to a gradual loss of nonclassicality and entanglement between the modes.     Editors' Suggestion Electromagnetically-induced-transparency spectra of Rydberg atoms dressed with dual-tone radio-frequency fields Maitreyi Jayaseelan, Andrew P. Rotunno, Nikunjkumar Prajapati, Samuel Berweger, Alexandra B. Artusio-Glimpse, Matthew T. Simons, and Christopher L. Holloway Phys. Rev. A 108, 033712 (2023) – Published 22 September 2023 Rydberg atoms driven by radio-frequency (rf) fields can be used as very sensitive electric-field detectors. Here, the authors extend this concept to dual-frequency rf fields, and show that their theoretical modeling and experimental results match.       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.
