Absence of gravitationally induced entanglement in certain semi-classical theories of gravity

Ward Struyve·Oct 23, 2025

Bose et al. and Marletto and Vedral proposed an experiment to test whether gravity can induce entanglement between massive systems, arguing that the capacity to do so would imply the quantum nature of gravity. In this work, a class of semi-classical ...

No-broadcasting of non-Gaussian states

Kaustav Chatterjee, Ulrik Lund Andersen·Oct 23, 2025

Gaussian states are of fundamental importance in the physics of continuous-variable quantum systems. They are appealing for the experimental ease with which they can be produced, and for their compact and an elegant mathematical description. Neverthe...

Thermodynamic decoupling in the deep-strong coupling regime

S. Palafox, M. Salado-Mejía, M. Santiago-García +1 more·Oct 23, 2025

In the deep-strong coupling (DSC) regime, the interaction between light and matter exceeds their bare frequencies, leading to an effective decoupling. Theoretical and experimental evidence for this behavior has relied solely on measurements of local ...

Landau Polarons as Generators of Quantum-Coherent States

Arnab Ghosh, Patrick Brosseau, Dmitry N. Dirin +3 more·Oct 23, 2025

Since Landau's theory, polarons have been understood as quasiparticles in which charges are dressed by the lattice field, yet decades of transport and spectroscopic studies have yielded only static indirect renormalizations. Whether such dressing can...

Fragmentation of Virtual Orbitals for Quantum Computing: Reducing Qubit Requirements through Many-Body Expansion

Federico Zahariev, Mark S. Gordon·Oct 23, 2025

The development of quantum computing for molecular simulations is constrained by the limited number of qubits available on current Noisy Intermediate-Scale Quantum (NISQ) devices. The present work introduces the Virtual Orbital Fragmentation (FVO) me...

The generalized adiabatic theorem for extended lattice systems

Lennart Becker, Stefan Teufel, Marius Wesle·Oct 23, 2025

We prove an adiabatic theorem for infinitely extended lattice fermion systems with gapped ground states, allowing perturbations that may close the gap. The Heisenberg dynamics on the CAR-algebra is generated by a time dependent two-parameter family o...

Local-to-Global Entanglement Dynamics by Periodically Driving Impurities

Zhi-Xing Lin, Abhinav Prem, Shinsei Ryu +1 more·Oct 23, 2025

We study the entanglement dynamics of a one-dimensional spin chain subject to a local Floquet drive of a two-site impurity. We uncover a sharp transition in the entanglement dynamics as a function of the driving frequency. For large drive periods $T$...

Electrical-control of third-order nonlinearity via Fano interference

Deniz Eren Mol, İbrahim Asrın Üzgüç, Ulaş Eyüpoğlu +6 more·Oct 23, 2025

Programmable photonic computers necessitate the integration of electrically-tunable compact components into the photonic devices. In the state-of-the-art photonic quantum computers~(PQCs), phase-shift and displacement gates can be implemented in an e...

Hybrid Lattice Surgery: Non-Clifford Gates via Non-Abelian Surface Codes

Sheng-Jie Huang, Alison Warman, Sakura Schafer-Nameki +1 more·Oct 23, 2025

In universal fault-tolerant quantum computing, implementing logical non-Clifford gates often demands substantial spacetime resources for many error-correcting codes, including the high-threshold surface code. A critical mission for realizing large-sc...

$\mathbb{Z}_2$ lattice gauge theories: fermionic gauging, transmutation, and Kramers-Wannier dualities

Lei Su·Oct 23, 2025

We generalize the gauging of $\mathbb{Z}_2$ symmetries by inserting Majorana fermions, establishing parallel duality correspondences for bosonic and fermionic lattice systems. Using this fermionic gauging, we construct fermionic analogs of $\mathbb{Z...

The complexity of perfect quantum state classification

Nathaniel Johnston, Benjamin Lovitz, Vincent Russo +1 more·Oct 23, 2025

The problem of quantum state classification asks how accurately one can identify an unknown quantum state that is promised to be drawn from a known set of pure states. In this work, we introduce the notion of $k$-learnability, which captures the abil...

Co-Designing Quantum Codes with Transversal Diagonal Gates via Multi-Agent Systems

Xi He, Sirui Lu, Bei Zeng·Oct 23, 2025
