Any local Hamiltonian with ferromagnetic quantum many-body scars has a generalized Shiraishi-Mori form

Keita Omiya·Jan 16, 2026

Quantum many-body scars (QMBS) are nonthermal eigenstates embedded in otherwise thermal spectra. A broad class of exact QMBS is realized as fixed-momentum magnon states above a ferromagnetic reference state. Here we prove a structural theorem for thi...

Entanglement Distribution over a Polarization-Stabilized Aerial Fiber

Yicheng Shi, Jing Su, Anouar Rahmouni +9 more·Jan 16, 2026

We experimentally demonstrate the distribution of polarization-entangled photons across a 62-km, partially-aerial fiber. With polarization stabilization applied to the fiber link, we achieve a photon pair rate of approximately 1500 per second and obs...

Multiary gradings

Steven Duplij·Jan 16, 2026

This article develops a comprehensive theory of multiary graded polyadic algebras, extending the classical concept of group-graded algebras to higher-arity structures. We introduce the notion of grading by multiary groups and investigate various comp...

Convergence Properties of Good Quantum Codes for Classical Communication

Alptug Aytekin, Mohamed Nomeir, Lei Hu +1 more·Jan 16, 2026

An important part of the information theory folklore had been about the output statistics of codes that achieve the capacity and how the empirical distributions compare to the output distributions induced by the optimal input in the channel capacity ...

Heat, work, and fluctuations in a driven quantum resonator

Riya Baruah, Pedro Portugal, Jun-Zhe Chen +2 more·Jan 16, 2026

A central building block of a heat engine is the working fluid, which mediates the conversion of heat into work. In nanoscale heat engines, the working fluid can be a quantum system whose behavior and dynamics are non-classical. A particularly versat...
