Heralded generation of multipartite free-electron W-State entanglement
Published on 2026-09-01 by Du Ran, Jing-Yi Liu, Dan Jin, Shuai Liu, Reuven Ianconescu, Ze-Long He, Ji-Yuan Bai, Ya-Dong Li and Avraham Gover @IOP SCIENCE
Abstract: We propose a heralded protocol for transferring atomic single-excitation entanglement to free electrons in a sideband-resolved interaction geometry. Each electron couples locally to one two-level system, and projection of the atomic subsystem onto the all-ground state maps the atomic excitation manifold onto the electronic upper-sideband manifold. For uniform couplings and common detuning, the rotating-wave dynamics is solved analytically and yields an exact phase-matched electronic state. At re[...]
Our summary: The proposed protocol transfers atomic single-excitation entanglement to free electrons using a sideband-resolved interaction. It achieves an exact phase-matched electronic state and characterizes multipartite structure through correlation redistribution. Robustness analyses address various factors impacting heralding probability and fidelity.

Heralded ultrafast generation of macroscopic quantum states in matter with bright squeezed vacuum light
Published on 2026-07-15 by Shohei Imai @IOP SCIENCE
Abstract: We show that bright squeezed vacuum light, combined with a single-shot quadrature measurement of the post-interaction light, enables the ultrafast generation of macroscopic quantum states in matter. Although in the weak-coupling regime multiphoton quantum light leaves the unconditional matter state as a classical mixture due to light–matter entanglement, quadrature-based heralding prepares the matter in a Gaussian-weighted quantum superposition of laser-driven matter states. For an ensemble of[...]
Our summary: Bright squeezed vacuum light enables ultrafast generation of macroscopic quantum states in matter. Quadrature measurement prepares matter in a Gaussian-weighted quantum superposition.
