Physical Review A (PRA) is looking for a new part-time Associate Editor with international scientific standing in the area of quantum science to join our editorial team and become part of the stimulating academic endeavor to bring high-quality papers to our readership.

The authors offer an overview of progress and a future perspective of large-scale optical quantum entanglement. They cover a broad range of topics from the basics of continuous-variable optical quantum entanglement and a multiplexing methodology for the generation of large-scale quantum entanglement to future approaches toward practical usages of large-scale optical quantum entanglement. The content includes both pedagogical content and the search for future directions beyond the current frontier.

Physical Review A is excited to offer better visibility and a tailored abstract for our popular Letter articles.

The authors demonstrate how the interplay between intrachain and interchain interactions in a dipolar spin chain results in three distinct relaxation regimes: ergodic, characterized by rapid relaxation towards equilibrium; metastable, where the state is quasi-localized; and partially relaxed, exhibiting both partial ergodic and quasi-localized behaviors simultaneously.

The authors present quantum scattering calculations on magnetic Feshbach resonances (MFRs) in ultracold atom-molecule collisions. The calculations predict a wealth of experimentally detectable MFRs in Rb-SrF collisions and uncover new MFRs due to the intramolecular spin-rotation interaction. These results open up the possibility of unbiased theoretical simulations on MFRs in ultracold atom-molecule collisions with realistic interactions.

The authors explore candidates for a next-generation search for the electron electric dipole moment (eEDM) by experimentally measuring the vibrational loss channels in three Sr-containing nonlinear molecules. They conclude that SrNH${}_2$ is the optimal choice for a future laser-cooled molecule-based eEDM experiment.

The authors implemented full process tomography of a bosonic gate in a superconducting circuit using coherent states as probes. This approach allows for a transparent error budget and the detection of leakage errors.

The authors present a theoretical approach to investigate the dissociation of the ammonia molecule following a collision with a low-energy electron. The approach could be used to model the process for other molecules in low-temperature plasma.

The authors demonstrate that Kohn-Sham density-functional theory in its original form is not applicable to many open-shell atoms because no proper Kohn-Sham model system obeying the Aufbau principle exists. Perspectives to deal with this situation are outlined.

The authors investigate the dynamics of an interacting bosonic chain which can be made non-reciprocal through engineered coupling to the environment. They show the presence of directional motion both for single bosons and repulsively bound pairs, which can be exploited to make the two move in opposite directions.

The authors theoretically demonstrate that the quantum state of structured light can be transferred to the highly coherent atomic beam when structured photons are absorbed by a bound electron. The proposed scheme allows complex shaping of the atomic wavefront.

The policy requires authors to explain where research data can be found starting Sept. 4.

The authors propose a stochastic theoretical model that explains the dynamics of an alignment-based atomic magnetometer and verify the model in a series of experiments with good agreement. The results could potentially enable alignment-based magnetometers in real-time sensing tasks.

The authors propose the use of homodyne detection to detect phase shifts and show that this method is optimal for path-entangled coherent states. This is notable because homodyne measurements do not require photon counting, and the resulting sensitivity is independent of the value of the phase shift itself.

The authors study the dynamics of the pump mode in the down-conversion Hamiltonian using the cumulant expansion method, perturbation theory, and the full numerical simulation. They obtain the properties of the pump mode, such as depletion, entanglement, and squeezing for an experimentally relevant initial state.

The authors report on the experimental demonstration of laser cooling of bunched Li-like O^{5+} ion beams at ~64% of the speed of light in a heavy ion storage ring. The laser cooling technique and the simulation method developed in this work pave the way for laser cooling and precision laser spectroscopy experiments at future large heavy ion accelerator facilities.

The authors report a lifetime measurement for the lowest-lying excited electronic state of the radioactive molecule RaF. The lifetime of this state is important for designing experiments to demonstrate laser cooling of RaF, which is a key element of proposals for sensitive searches of new physics in the future.

When determining the authorship list for your next paper, be generous yet disciplined.
