Dicke Superradiance in Extended 2D Quantum Arrays Coupled to Metasurface Bound States in the Continuum
Daniel Eyles, Emmanuel Lassalle, Adam Stokes +2 more·Feb 4, 2026
Dicke superradiance is a collective phenomenon where the emission from ensembles of quantum emitters is coherently enhanced beyond the sum of each emitter's independent emission. Here, we propose a platform that exploits the delocalised nature of a h...
VRARE: Using Virtual Reality to Understand Accessibility Requirements of Color Blindness and Weakness
Yi Wang, Ben Cheng, Xiao Liu +3 more·Feb 4, 2026
In this paper, we developed a virtual reality (VR) system that can simulate color blindness and weakness. We built an immersive 3D web view interface where participants can discuss accessibility requirements for a fitness website projects within a vi...
Entanglement improves coordination in distributed systems
Francisco Ferreira da Silva, Stephanie Wehner·Feb 4, 2026
Coordination in distributed systems is often hampered by communication latency, which degrades performance. Quantum entanglement offers fundamentally stronger correlations than classically achievable without communication. Crucially, these correlatio...
Agnostic Parameter Estimation with Large Spins
Huining Zhang, X. X. Yi·Feb 4, 2026
The quantum Fisher information of a quantum state with respect to a certain parameter quantifies the sensitivity of the quantum state to changes in that parameter. Maximizing the quantum Fisher information is essential for achieving the optimal estim...
Restoring Landauer's Principle for Unitarily Transformed Thermal Reservoirs
Hao Xu·Feb 4, 2026
Landauer's principle, a cornerstone of quantum information and thermodynamics, appears to be violated when the thermal reservoir is replaced by a squeezed thermal state (STS). We introduce a formal extension of the principle to such unitarily transfo...
Locally Gentle State Certification for High Dimensional Quantum Systems
Cristina Butucea, Jan Johannes, Henning Stein·Feb 4, 2026
Standard approaches to quantum statistical inference rely on measurements that induce a collapse of the wave function, effectively consuming the quantum state to extract information. In this work, we investigate the fundamental limits of \emph{locall...
Effect of initial intrasystem entanglement on entropy growth in generalized Jaynes-Cummings models
Daria Gaidukevich·Feb 4, 2026
We investigate how initial intrasystem entanglement influences the entropy generated in atomic systems interacting with a photonic environment in several generalizations of the Jaynes-Cummings model with two or more subsystems. Since the initial enta...
Thermodynamic Cost of Regeneration in a Quantum Stirling Cycle
Ferdi Altintas·Feb 4, 2026
We study the regenerative quantum Stirling heat engine cycle within the standard weak-coupling, Markovian open quantum system framework. We point out that the regeneration process is not thermodynamically free in a reduced open-system description, an...
A simple means for deriving quantum mechanics
Eric Tesse·Feb 4, 2026
A type of mechanics will be presented that possesses some distinctive properties. On the one hand, its physical description & rules of operation are readily comprehensible & intuitively clear. On the other, it fully satisfies all observable predictio...
$C$-$ΔΘ$: Circuit-Restricted Weight Arithmetic for Selective Refusal
Aditya Kasliwal, Pratinav Seth, Vinay Kumar Sankarapu·Feb 4, 2026
Modern deployments require LLMs to enforce safety policies at scale, yet many controls rely on inference-time interventions that add recurring compute cost and serving complexity. Activation steering is widely used, but it requires runtime hooks and ...
Squeezing-Enhanced Rotational Doppler Metrology
Javier Navarro, Mateo Casariego, Gabriel Molina-Terriza +2 more·Feb 4, 2026
A rotating surface can induce a frequency shift in incident light by changing its angular momentum, a phenomenon known as the rotational Doppler effect. This effect provides a means to estimate the angular velocity of the rotating surface. In this wo...
PhoQuPy: A Python framework for Automation of Quantum Optics experiments
Srivatsa Murali, Anshuman Kumar·Feb 4, 2026
We present the automation of a confocal photoluminescence (PL) scanning system for the identification and characterization of single-photon emitters (SPEs) in quantum materials. The setup excites the sample with a laser and acquires a spectrum at eac...
Quantum-Based Resilient Routing in Networks: Minimizing Latency Under Dual-Link Failures
Maher Harb, Nader Foroughi, Matt Stehman +3 more·Feb 4, 2026
Network optimization problems represent large combinatorial search spaces that grow exponentially with network size, making them computationally intensive to solve. This paper addresses the latency-resilient Layer 3 routing optimization problem in te...
From Florence to Fermions: a historical reconstruction of the origins of Fermi's statistics one hundred years later
Roberto Casalbuoni, Daniele Dominici·Feb 4, 2026
Aim of this paper is to retrace the path that led the young Enrico Fermi to write his paper on the statistics of an ideal monatomic gas. This discovery originated in his interest, which he had shown since his formative years, in the absolute entropy ...
Optimal Control Design Guided by Adam Algorithm and LSTM-Predicted Open Quantum System Dynamics
JunDong Zhong, ZhaoMing Wang·Feb 4, 2026
The realization of high-fidelity quantum control is crucial for quantum information processing, particularly in noisy environments where control strategies must simultaneously achieve precise manipulation and effective noise suppression. Conventional...
Influence of environment on quantum correlations in two-spin systems with dipole-dipole interactions
G. A. Bochkin, E. B. Fel'dman, E. I. Kuznetsova +1 more·Feb 4, 2026
An influence of environment on quantum correlations (entanglement and quantum discord) is studied in a two-spin-1/2 system with dipole-dipole interactions on the basis of Lindblad equation. We consider the simplest case when the environment causes on...
Qudit Twisted-Torus Codes in the Bivariate Bicycle Framework
Mourad Halla·Feb 4, 2026
We study finite-length qudit quantum low-density parity-check (LDPC) codes from translation-invariant CSS constructions on two-dimensional tori with twisted boundary conditions. Recent qubit work [PRX Quantum 6, 020357 (2025)] showed that, within the...
