Universality in Ionic Three-body Systems Near an Ion-atom Feshbach Resonance

Jacek Gȩbala, Michał Tomza, José P. D'Incao·Nov 1, 2025

We calculate bound and scattering properties of a system of two neutral atoms and an ion near an atom-ion Feshbach resonance. Our results indicate that long-range atom-ion interactions lead to significant deviations from universal behavior derived fr...

Optimal transfer of entanglement in oscillator chains in non-Markovian open systems

Da-Wei Luo, Edward Yu, Ting Yu·Oct 31, 2025

We considered the transfer of continuous-variable entangled states in coupled oscillator chains embedded in a generic environment. We demonstrate high-fidelity transfer via optimal control in two configurations - a linear chain and an X-shaped chain....

Local perception operators and classicality: new tools for old tests

Rohit Kishan Ray·Oct 31, 2025

Quantum nonlocality is often judged by violations of Bell-type inequalities for a given state. The computation of such violations is a global task, requiring evaluation of global correlations and subsequent testing against a Bell functional. We ask i...

Quantum-dot single photon source performance with off-resonant pulse preparation schemes

Gavin Crowder, Lora Ramunno, Stephen Hughes·Oct 31, 2025

The preparation of photonic qubits in the excited state is an integral part of the performance of an on-demand single photon source (SPS). Conventional resonant excitation, an excellent approach to maximize the coherence and indistinguishability of t...

Magnetic field in vacuum of quantum spinor matter induced by a cosmic string in three-dimensional space

Yu. I. Pylypchuk, P. O. Nakaznyi, O. V. Barabash +2 more·Oct 31, 2025

A linear magnetic topological defect (cosmic string) is modeled as a magnetic flux-carrying tube that is impenetrable to external spinor matter. The matter field is quantized in the background of this tube, with the most general set of boundary condi...

Closed-loop calculations of electronic structure on a quantum processor and a classical supercomputer at full scale

Tomonori Shirakawa, Javier Robledo-Moreno, Toshinari Itoko +18 more·Oct 31, 2025

Quantum computers must operate in concert with classical computers to deliver on the promise of quantum advantage for practical problems. To achieve that, it is important to understand how quantum and classical computing can interact together, and ho...

Simulated outperforms quantum reverse annealing in mean-field models

Christopher L. Baldwin·Oct 31, 2025

Adiabatic reverse annealing (ARA) has been proposed as an improvement to conventional quantum annealing for solving optimization problems, in which one takes advantage of an initial guess at the solution to suppress problematic phase transitions. Her...

Chimeric states of matter: Meissner effect without superconductivity

Michael J Landry, Mingda Li·Oct 31, 2025

Symmetry is central to how we classify phases of matter: solids break spatial translations, superfluids break particle-number conservation, and superconductors "break" gauge symmetry. Mixed anomalies involving higher-form symmetries, however, present...

Rydberg Single Photon Detection for Probing 0.1-10 meV Dark Matter with BREAD

Abhishek Banerjee, Reza Ebadi, Surjeet Rajendran·Oct 31, 2025

We introduce a Rydberg-based single photon detector (SPD) for probing dark matter in the 0.1-10 meV mass range (20 GHz-2 THz). The Rydberg SPD absorbs photons produced and focused by the BREAD dish antenna and trades them for free, detectable electro...
