Boosting Gravity-Induced Entanglement through Parametric Resonance

Yuka Shiomatsu, Youka Kaku, Akira Matsumura +1 more·Nov 12, 2025

Establishing quantum gravity theory remains one of the major challenges in modern physics, as the lack of experimental evidence makes it difficult to explore. In response to this challenge, proposals to test quantum entanglement induced by Newtonian ...

Enhanced spectral range of strain-induced tuning of quantum dots in circular Bragg grating cavities

Ivan Gamov, Matthias Sauter, Samuel Huber +5 more·Nov 12, 2025

Tunable sources of entangled and single photons are essential for implementing entanglement-based quantum information protocols, as quantum teleportation and entanglement swapping depend on photon indistinguishability. Tunable devices are fabricated ...

Coherence in the Leak and Storage Kurtosis control Ergotropy in Quantum Batteries

Bitap Raj Thakuria, Trishna Kalita, Manash Jyoti Sarmah +1 more·Nov 11, 2025

We introduce a cavity-coupled finite quantum system which can act as a quantum battery by harnessing noise induced coherences. We apply the methodology of full counting statistics to capture higher-order fluctuations of quanta exchange in the storage...

On the role of induced electric field in the time-dependent Aharonov-Bohm effect

Masashi Wakamatsu·Nov 11, 2025

Whether the time-dependent Aharonov-Bohm (AB) effect even exists or not has been the subject of long-standing debate. There are two factors complicating the problem. First, in the closed spacetime line integral of the vector potential that is thought...

Multipartite steering verification with imprecise measurements

Zeyang Lu, Chan Li, Gang Wang +1 more·Nov 11, 2025

Quantum steering is a fundamental quantum correlation that plays a pivotal role in quantum technologies, but its verification crucially relies on precise measurements -- an assumption often undermined by practical imperfections. Here, we investigate ...

Dual Magnetic and Electric Dipole Symmetry: Pseudo Angular Momentum in Parity Space and the Electric Landé $g$-Factor

Michael E. Tobar·Nov 10, 2025

EDMs probe fundamental symmetries and underpin BSM searches. We give a symmetry-based description, analogous to the Zeeman effect, that puts magnetic and electric dipoles on equal footing under EM duality. In hydrogen, $\vec B$ (pseudovector) couples...

Magnon-Squeezing-Induced Nonreciprocal Quantum Coherence in a Cavity Magnomechanical System

Abdelkader Hidki, Amjad Sohail, Tesfay Gebremariam Tesfahannes +2 more·Nov 9, 2025

We investigate quantum coherence in a hybrid cavity magnomechanical system incorporating a squeezed-magnon drive. By analyzing the Gaussian quantum coherence of the cavity, magnonic, and mechanical subsystems, as well as the total system coherence, w...

Active Noise Reduction in Si/SiGe Gated Quantum Dots

Rajat Bharadwaj, Parvathy Gireesan, Harikrishnan Sundaresan +5 more·Nov 9, 2025

Solid-state quantum technologies such as quantum dot qubits and quantum electrical metrology circuits rely on quantum phenomena at ultra-low energies, making them highly sensitive to various forms of environmental noise. Conventional passive filterin...

Electrostatics-induced breakdown of the integer quantum Hall effect in cavity QED

Gian Marcello Andolina, Zeno Bacciconi, Alberto Nardin +3 more·Nov 6, 2025

We analyze the recently observed breakdown of the integer quantum Hall effect in a two-dimensional electron gas embedded in a metallic split-ring resonator. By accounting for both the quantized vacuum field and electrostatic boundary modifications, w...

Mixed-State Measurement-Induced Phase Transitions in Imaginary-Time Dynamics

Yi-Ming Ding, Zenan Liu, Xu Tian +3 more·Nov 6, 2025

Mixed-state phase transitions have recently attracted growing attention as a new frontier in nonequilibrium quantum matter and quantum information. In this work, we introduce the measurement-dressed imaginary-time evolution (MDITE) as a novel framewo...

Quantum Entanglement as a Cohomological Obstruction

Controllable Non-Hermitianity in Continuous-Variable Qubits

Ke-Xiong Yan, Zhi-Cheng Shi, Ye-Hong Chen +1 more·Nov 6, 2025

Pure dephasing is the dominant leak mechanism in photonic cat qubits because its phase errors disrupt the parity protection, rendering the qubit vulnerable to energy relaxation. In this manuscript, we reveal that this dephasing mechanism conceals an ...

Krylov Complexity Meets Confinement

Xuhao Jiang, Jad C. Halimeh, N. S. Srivatsa·Nov 5, 2025

In high-energy physics, confinement denotes the tendency of fundamental particles to remain bound together, preventing their observation as free, isolated entities. Interestingly, analogous confinement behavior emerges in certain condensed matter sys...
