Small clusters of He atoms in finite-cutoff EFT
Betzalel Bazak·Nov 16, 2025
Small clusters of $^4$He atoms provide a paradigmatic setting for exploring universal phenomena in few-body quantum systems with large scattering length. Their weakly bound states serve as ideal test cases for studying Efimov physics and the emergenc...
Minute-Scale Photonic Quantum Memory
You-Cai Lv, Yu-Jia Zhu, Zong-Quan Zhou +2 more·Nov 16, 2025
Long-lived storage of single photons is a fundamental requirement for enabling quantum communication and foundational tests of quantum physics over extended distances. While the implementation of a global-scale quantum network requires quantum storag...
Autonomously Designed Pulses for Precise, Site-Selective Control of Atomic Qubits
Sanghyo Park, Seuk Lee, Keunyoung Lee +2 more·Nov 16, 2025
Quantum computers based on cold-atom arrays offer long-lived qubits with programmable connectivity, yet their progress toward fault-tolerant operation is limited by the relatively low fidelity of site-selective local control. We introduce an artifici...

Nonlocal action in Everettian Quantum Mechanics
Mordecai Waegell, Kelvin J. McQueen·Nov 16, 2025
According to a common view, Everettian quantum mechanics (EQM) is a local theory because it avoids nonlocal action at a distance, and this is an important point in EQM's favor. Unlike collapse theories, EQM does not allow an action on one system to c...
