Summary: Quantum particles move in complex ways that are not limited by classical causality, and quantum interference can raise probabilities beyond classical limits. Traditional interference methods can be used to prepare particles to hit two targets simultaneously in a quantum state, surpassing classical constraints. However, the uncertainty principle complicates the process of determining particle hits due to the disturbance caused by physical detection.

Summary: We present calculations of Delbruck scattering with all-order Coulomb corrections for photon energies above the electron-positron pair creation threshold. Our method utilizes the Dirac-Coulomb Green's function and accounts for the interaction between the virtual electron-positron pair and the nucleus to all orders in the nuclear binding strength parameter αZ. Practical calculations are performed for 2.754 MeV photon scattering off plutonium atoms. Our results show that including the Coulomb corrections increases the scattering cross section by up to 50% in this case, resolving the long-standing discrepancy between experimental data and theoretical predictions.

Summary: By combining the controlled breaking of time-reversal symmetry with non-Hermitian dynamics, researchers have imposed chirality on phononic states, leading to unique symmetries and dynamics. Through time-modulated radiation pressure forces in nano-optomechanical networks, time-reversal symmetry is broken and chiral energy flow among mechanical resonators is observed. Furthermore, introducing non-conserving squeezing interactions, they observe a non-Hermitian Aharonov-Bohm effect and phononic amplification in ring-shaped networks, opening up new possibilities for exploring non-Hermitian topological bosonic phases and applications.

Summary: This study examines the precision limits of Hong-Ou-Mandel timing measurements as well as the precision limits of generalized two-photon measurements. It is found that maximizing measurement precision in the case of unequal photon bandwidths requires a tradeoff between high interference visibility and strong frequency anticorrelations. The precision limits of generalized measurements are qualitatively similar to those of Hong-Ou-Mandel measurements when the generalized measurements are insensitive to the net delay of both photons.

Summary: The article introduces the concept of nonreciprocal quantum photonic operations and demonstrates the basis for such a nonreciprocal transformation in the frequency domain through intermodal Bragg scattering four-wave mixing. The process preserves the coherence of quantum optical states, yielding approximately 25 dB of nonreciprocal contrast, and outlines the potential to scale efficiencies to near-unity values.

Summary: The growing demand for bandwidth has made photonic systems a leading candidate for future telecommunication and radar technologies. However, it remains challenging to realize narrowband filters needed for high-performance communications systems using integrated photonics. In this study, the authors demonstrate all-silicon microwave-photonic notch filters with significantly higher spectral resolution by utilizing optomechanical interactions to access long-lived phonons in silicon.

Summary: This paper demonstrates strong coupling in a Brillouin-based bulk cavity optomechanical system, showing efficient, high-bandwidth, and deterministic transfer of quantum states as well as control of mechanical motion. By creating hybridized photonic-phononic modes through mode hybridizations, the system exhibits significantly longer lifetimes than an uncoupled system. Additionally, the bulk-acoustic-wave resonators supported phonons in this system have properties such as high frequencies, long coherence times, and robustness against thermal decoherence.

Summary: The best performance from compact, portable, and repeatably manufactured electromagnetic (EM) oscillators has for decades been built upon crystalline quartz resonators operating at radio frequencies. However, meeting demands for increased measurement sensitivity requires pushing beyond a fractional frequency stability of 10-13, typical of the best ovenized quartz. Here we demonstrate the validity of a manufacturable, compact Fabry-Perot reference that improves upon all other centimeterscale oscillators by more than a factor of 10, including those based on solid-state optical resonators as well as quartz.
