Author(s): B.-B. Liu, D.-Y. Wang, J. Tang, G. Chen, H. Jing, Shi-Lei Su, and F. Nori Reservoir engineering enables unidirectional energy and signal flow. We establish squeezing-induced symmetry breaking between two cavities as a guiding principle for exponentially amplifying reservoir-mediated nonreciprocity. Rather than a simple scaling of the coupling, this mechanism strategically… [Phys. Rev. Lett. 136, 253602] Published Wed Jun 24, 2026

Author(s): Jorge Olmos-Trigo, Cristina Sanz-Fernández, and Ivan Fernandez-Corbaton Chiral objects typically exhibit a different extinction for the two circular polarizations of light. Researchers often detect the chirality of objects by measuring this extinction difference employing circular dichroism spectroscopy. In this Letter, we present a new spectroscopy technique for detect… [Phys. Rev. Lett. 136, 253802] Published Wed Jun 24, 2026

Author(s): G. Keijsers, R. M. de Boer, B. Verdonschot, K. J. H. Peters, and S. R. K. Rodriguez We demonstrate thermodynamic irreversibility in the stochastic switching of a coherently driven bistable optical cavity. We present measurements of phase space probability currents evidencing the breaking of detailed balance associated with thermodynamic irreversibility. We also estimate the magnitu… [Phys. Rev.

Author(s): R. A. Jenkins, M. T. Ziemba, F. J. Collings, X. S. Zheng, F. Castellini, E. Wursten, J. Lim, B. E. Sauer, and M. R. Tarbutt We describe a spin interferometer using ultracold YbF molecules and develop the complete set of techniques needed to measure the electron’s electric dipole moment, ${d}_{e}$, with this apparatus. The molecules are cooled in an optical molasses and prepared in a single internal quantum state. A Raman… [Phys....

Author(s): Junghoon Lee, Jongmin Kim, Jongheum Jung, and Y. Shin Turbulence enhances momentum transport in classical fluids, effectively increasing their viscosity. We investigate an analogous effect in a superfluid by measuring the damping of collective oscillations in an atomic Bose-Einstein condensate (BEC) containing stationary spin-superflow turbulence. Usin… [Phys. Rev. Lett. 136, 253402] Published Tue Jun 23, 2026

Author(s): Vikram Kashyap, Caleb Walton, and Sara Mouradian Optical crosstalk due to imperfect addressing in trapped-ion entangling gates generates unwanted nonlocal entanglement between target ions and their combined set of neighbors that is difficult to mitigate using standard quantum error correction. We present a method to design entangling operations th… [Phys. Rev. Lett. 136, 253601] Published Tue Jun 23, 2026

Author(s): Xiaojie Wang, Lin Zhou, Yue Li, Sakthi Sanjeev Mohanraj, Xiaodong Shi, Zhuoyang Yu, Ran Yang, Xu Chen, Guangxing Wu, Hao Hao, Sihao Wang, Veerendra Dhyani, and Di Zhu On-chip generation of high-purity single photons is essential for scalable photonic quantum technologies. Spontaneous parametric down conversion (SPDC) is widely used to generate photon pairs for heralded single-photon sources, but intrinsic spectral correlations of the...
