Pair scattering from time-modulated impurity in the Bose-Hubbard model
Neda Ahmadi, Ameneh Sheikhan, Corinna Kollath·Nov 21, 2025
We investigate scattering phenomena in a one-dimensional attractive Bose-Hubbard model with a time-periodically modulated impurity. We analyze both single-particle and pair (doublon) transmission, exploring a range of interaction strengths and drive ...
50-km fiber interferometer for testing gravitational signatures in quantum interference
Haocun Yu, Dorotea Macri, Thomas Morling +10 more·Nov 21, 2025
Quantum mechanics and general relativity are the foundational pillars of modern physics, yet experimental tests that combine the two frameworks remain rare. Measuring optical phase shifts of massless photons in a gravitational potential provides a un...
Bell state analysis using orbital angular momentum and path degrees of freedom
Zi-Long Yang, Shi-Wen He, Lin-Cheng Wang +4 more·Nov 21, 2025
Bell state analysis (BSA) constitutes a foundational operation for distinguishing Bell states in numerous quantum information processing (QIP) protocols. In this work, we propose a theoretical scheme for realizing a perfect BSA tailored for polarized...
A Hybrid Classical-Quantum Fine Tuned BERT for Text Classification
Abu Kaisar Mohammad Masum, Naveed Mahmud, M. Hassan Najafi +1 more·Nov 21, 2025
Fine-tuning BERT for text classification can be computationally challenging and requires careful hyper-parameter tuning. Recent studies have highlighted the potential of quantum algorithms to outperform conventional methods in machine learning and te...
All steerable quantum correlations can provide thermodynamic advantages in cooling
Tanmoy Biswas, Chandan Datta, Luis Pedro Garcia-Pintos·Nov 21, 2025
The removal of heat generated during computation poses a major challenge for both classical and quantum information processing. In particular, heat removal is directly linked to a fundamental requirement of quantum computation: the ability to reset a...
Canonical Quantum Mpemba Effect in a Dissipative Qubit
Xingli Li, Yan Li, Yangqian Yan·Nov 21, 2025
The Mpemba effect, where a hotter system cools faster than a colder one under otherwise identical conditions, has been extensively studied in classical systems. In this work, we present the quantum analogue of the Mpemba effect using a dissipative qu...
Lane-Frame Quantum Multimodal Driving Forecasts for the Trajectory of Autonomous Vehicles
Navneet Singh, Shiva Raj Pokhrel·Nov 21, 2025
Trajectory forecasting for autonomous driving must deliver accurate, calibrated multi-modal futures under tight compute and latency constraints. We propose a compact hybrid quantum architecture that aligns quantum inductive bias with road-scene struc...
Quantum Jump Approach for Photosynthetic Energy Transfer with Chemical Reaction and Fluorescence Loss
Rui Li, Yi Li, Kai-Ya Zhang +1 more·Nov 21, 2025
Recently, the coherent modified Redfield theory (CMRT) has been widely used to simulate the excitation-energy-transfer (EET) processes in photosynthetic systems. However, the numerical simulation of the CMRT is computationally expensive when dealing ...
Quantum Storage of Frequency-Multiplexed Photons Exhibiting Nonclassical Correlations with Telecom C-Band Photons
Hiroki Tateishi, Daisuke Yoshida, Tomoki Tsuno +6 more·Nov 21, 2025
Multiplexing is essential for improving entanglement distribution rates in quantum communication. Frequency multiplexing provides a promising and scalable path toward large-capacity quantum networks. Further progress requires increasing the number of...

Wouter Verstraelen, Stanisław Świerczewski, Andrzej Opala +7 more·Nov 21, 2025
Characterising optical quantum states is essential for the development of quantum technologies. While traditional approaches to perform full quantum state tomography are often experimentally demanding, neuromorphic architectures may provide an effect...
Exponentially enhanced sensing through nonreciprocal light propagation
Paul-Édouard Blanchard, Alexander McDonald, Philippe St-Jean·Nov 21, 2025
Non-reciprocity is a key resource for pushing the performance of photonic devices beyond the fundamental limits imposed by Lorentz reciprocity. Here, we report on the realization of an optical sensor where non-reciprocal light propagation allows dete...
