Horizon-Restricted Leading Soft QED as Open Quantum System

Soo-Jong Rey·Jul 8, 2026

I formulate black-hole-horizon-induced decoherence of charged branch codes as the leading-soft QED restricted to an exterior algebra, formulated as an open quantum system. The fixed-history Feynman--Vernon identity ${\cal F}[J,J]=1$ remains exact. De...

Quantum simulation of real-world nonlinear dynamics via Koopman method

Baoyang Zhang, Dong An, Zhaoyuan Meng +4 more·Jul 8, 2026

Nonlinear dynamics is ubiquitous in nature, ranging from chemical pattern formation to ocean circulation, yet its simulation on quantum computers is fundamentally limited by the unitary nature of quantum evolution. We propose the quantum Koopman meth...

Resource-Efficient Hybrid Quantum Neighborhood Selection for Large-Scale Molecular Diversity Optimization

Nicolas Mendes de Araujo, Lester de Abreu Faria·Jul 8, 2026

Large-scale combinatorial optimization remains demanding for classical heuristics, particularly when dense Quadratic Unconstrained Binary Optimization (QUBO) formulations induce large memory footprints, high CPU utilization, and long execution times....

Lecture notes on classical and quantum non-Markovianity

Graeme Pleasance·Jul 8, 2026

The study of non-Markovian quantum processes has attracted significant interest in recent decades, giving rise to several competing notions of quantum non-Markovianity. These notes serve as an introduction to the topic for graduate students familiar ...

-8 dB SNR + 90% Packet Loss: MamVSC -- CSI-Guided Semantic Mamba for Extreme-Robust Video Semantic Communication

Lei Teng, Senran Fan, Chen Dong +3 more·Jul 8, 2026

Semantic communication, leveraging joint source-channel coding, is designed to mitigate semantic distortion introduced by the channel. However, most current studies focus solely on semantic deviation distortion caused by physical wireless channels, w...

Quantum Boomerang Effect in Time-Crystalline Structures

Qi-wen Peng, Krzysztof Sacha, Chu-hui Fan·Jul 8, 2026

The quantum boomerang effect (QBE) is a unique dynamical signature of Anderson localization, characterized by a launched wavepacket that initially drifts but ultimately returns to its initial position due to fundamental quantum interference. In this ...

Non-Abelian Thouless pumping based on the global adiabatic criterion in Rydberg synthetic lattices

Jin-Kang Guo, Jin-Lei Wu, Chuan-Cun Shu·Jul 8, 2026

We study a quantum implementation of non-Abelian Thouless pumping in Lieb lattices using Rydberg synthetic dimensions. The lattice is encoded in twelve selected microwave-coupled Rydberg levels, forming a three-cell structure with six degenerate zero...

Quantum Computing : A New Frontier for Science and Society

Giuseppe Di Molfetta·Jul 8, 2026

This short report explores the (non exhaustive) current state of quantum technologies, their potential applications, and the challenges that must be addressed to harness their full potential. In particular we will focus on the quantum computer archit...

Analytical Landscape of Maximal Magic for Two-Qutrit States and Beyond

Marco Knipfer, Alexander Roman, Katia Matcheva +1 more·Jul 8, 2026

Achieving a genuine quantum advantage relies on two distinct non-classical resources that restrict efficient classical simulation: entanglement and magic (nonstabilizerness). We investigate the interplay between these resources by characterizing the ...

Macroscopic position-position entanglement by photon recoil in Rydberg atoms

Xiao-Feng Shi·Jul 8, 2026

Entanglement between two spatially separate matter particles can be generated via many means and often resides in the internal states of particles. Here, via Rydberg blockade in two spatially separate neutral atoms, we find that the photon recoil in ...

Dynamical structure factor with a pumping approach on a trapped-ion quantum computer

Etienne Granet, Keisuke Murota, Henrik Dreyer +3 more·Jul 8, 2026

Dynamical structure factors (DSF) measured with neutron-scattering experiments provide key insights into the structure of materials. Their computation requires both the preparation of an equilibrium state and the implementation of Hamiltonian dynamic...

Density effects in precision laser spectroscopy of exotic helium atoms

Hubert J. Jóźwiak, Dimitar Bakalov, Michał Przybytek +2 more·Jul 8, 2026

Exotic helium atoms act as unique atomic traps for heavy, negatively charged particles, protecting them from nuclear annihilation and nuclear capture on timescales long enough to enable high-precision laser spectroscopy. Such measurements serve as st...

Room-temperature inversionless diamond nitrogen-vacancy electronic spin maser

Ali Fawaz, Sarath Raman Nair·Jul 8, 2026

We propose a method to create a room-temperature maser operating at approximately 2.9~GHz frequency using an ensemble of negatively charged nitrogen-vacancy electronic spins (NV) in diamond, without requiring population inversion. Our method consider...

Phase-Selected Efficient Single-Photon Frequency Conversion via Local Fano Resonance in a Two-Giant-Atom Waveguide-QED System

Qing-Ao Xiang, Yan Liu, Xin-Yuan Yang +1 more·Jul 8, 2026

Efficient single-photon frequency conversion is investigated in a two-giant-atom waveguide-QED system, where a two-level giant atom and a $Λ$-type three-level giant atom couple to a common one-dimensional waveguide. While the $Λ$-type atom provides t...

Spectral Chaos Does Not Determine Quantum Mpemba Crossings

Ri-Hua Zheng, Yang Xiao, Yu Wang +2 more·Jul 8, 2026

In a symmetry-restoration quantum Mpemba effect, an initial state with stronger local symmetry breaking can lose that memory faster than a state that starts closer to the symmetric manifold. We test whether this local ordering reversal is organized b...
