Detecting multilevel entanglement from light-based entanglement witnesses
Pedro Rosario, Romain Bachelard·Feb 9, 2026
We introduce a set of electric-field based inequalities capable of detecting multilevel entanglement from a system of N quantum emitters. We determine that the polarization channel as well as the direction of detection can enhance entanglement detect...
AI-Driven Cardiorespiratory Signal Processing: Separation, Clustering, and Anomaly Detection
Yasaman Torabi·Feb 9, 2026
This research applies artificial intelligence (AI) to separate, cluster, and analyze cardiorespiratory sounds. We recorded a new dataset (HLS-CMDS) and developed several AI models, including generative AI methods based on large language models (LLMs)...
Spinor Double-Quantum Excitation in the Solution NMR of Near-Equivalent Spin-1/2 Pairs
Urvashi D. Heramun, Mohamed Sabba, Dolnapa Yamano +5 more·Feb 8, 2026
A family of double-quantum excitation schemes is described for the solution nuclear magnetic resonance (NMR) of near-equivalent spin-1/2 pairs. These new methods exploit the spinor behaviour of 2-level systems, whose signature is the change of sign o...
Permanents of matrix ensembles: computation, distribution, and geometry
Igor Rivin·Feb 8, 2026
We report on a computational and experimental study of permanents. On the computational side, we use the GPU to greaatly accelerate the computation of permanents over $\mathbb{C},$ $\mathbb{R},$ $\mathbb{F}_p$ and $\mathbb{Q}.$ First, for Haar-distri...
Quantum Estimation of Delay Tail Probabilities in Scheduling and Load Balancing
R. Srikant·Feb 8, 2026
Estimating delay tail probabilities in scheduling and load balancing systems is a critical but computationally prohibitive task due to the rarity of violation events. Quantum Amplitude Estimation (QAE) offers a generic quadratic reduction in sample c...
Optimal Quantum Speedups for Repeatedly Nested Expectation Estimation
Yihang Sun, Guanyang Wang, Jose Blanchet·Feb 8, 2026
We study the estimation of repeatedly nested expectations (RNEs) with a constant horizon (number of nestings) using quantum computing. We propose a quantum algorithm that achieves $\varepsilon$-error with cost $\tilde O(\varepsilon^{-1})$, up to loga...
An efficient method for spot-checking quantum properties with sequential trials
Yanbao Zhang, Akshay Seshadri, Emanuel Knill·Feb 8, 2026
In practical situations, the reliability of quantum resources can be compromised due to complex generation processes or adversarial manipulations during transmission. Consequently, the trials generated sequentially in an experiment may exhibit non-in...
Objective Decoupling in Social Reinforcement Learning: Recovering Ground Truth from Sycophantic Majorities
Majid Ghasemi, Mark Crowley·Feb 8, 2026
Contemporary AI alignment strategies rely on a fragile premise: that human feedback, while noisy, remains a fundamentally truthful signal. In this paper, we identify this assumption as Dogma 4 of Reinforcement Learning (RL). We demonstrate that while...
The CAPSARII Approach to Cyber-Secure Wearable, Ultra-Low-Power Networked Sensors for Soldier Health Monitoring
Luciano Bozzi, Christian Celidonio, Umberto Nuzzi +15 more·Feb 8, 2026
The European Defence Agency's revised Capability Development Plan (CDP) identifies as a priority improving ground combat capabilities by enhancing soldiers' equipment for better protection. The CAPSARII project proposes in innovative wearable system ...
Graph-Enhanced Deep Reinforcement Learning for Multi-Objective Unrelated Parallel Machine Scheduling
Bulent Soykan, Sean Mondesire, Ghaith Rabadi +1 more·Feb 8, 2026
The Unrelated Parallel Machine Scheduling Problem (UPMSP) with release dates, setups, and eligibility constraints presents a significant multi-objective challenge. Traditional methods struggle to balance minimizing Total Weighted Tardiness (TWT) and ...
Quantum Walks Assisted Bidirectional Remote State Preparation
K. K. Naseeda, Jumana Muhammed Abdul Asharaf, N. C. Randeep·Feb 8, 2026
We present a scheme for bidirectional remote state preparation (BRSP) using quantum walks on two independent one-dimensional lattices and two independent cycles with two and four vertices, employing nearest-neighbor jumps with coin outcomes. The prot...
Information-Theoretic Gaps in Solar and Reactor Neutrino Oscillation Measurements
Neetu Raj Singh Chundawat, Yu-Feng Li·Feb 8, 2026
Quantum estimation theory provides a fundamental framework for analyzing how precisely physical parameters can be estimated from measurements. Neutrino oscillations are characterized by a set of parameters inferred from experiments conducted in diffe...
Improved entanglement-based high-dimensional optical quantum computation with linear optics
Huan-Chao Gao, Guo-Zhu Song, Hai-Rui Wei·Feb 8, 2026
Quantum gates are the essential block for quantum computer. High-dimensional quantum gates exhibit remarkable advantages over their two-dimensional counterparts for some quantum information processing tasks. Here we present a family of entanglement-b...
Quantum self-interaction within an infinitely deep cavity
Sergio Giardino·Feb 8, 2026
One examines the infinitely deep quantum cavity, also known as the quantum infinite square well, within the framework of the real Hilbert space. The solutions are considered in terms of complex wave functions, and also in terms of quaternionic wave f...
Higher-Order Corrections to Scrambling Dynamics in Brownian Spin SYK Models
Tingfei Li, Miao Wang, Jianghui Yu·Feb 8, 2026
We investigate operator growth in a Brownian spin Sachdev--Ye--Kitaev (SYK) model with random all-to-all interactions, focusing on the full operator-size distribution. For Hamiltonians containing interactions of order two up to $L$, we derive a close...
Full Schmidt characterization of spatiotemporally entangled states produced from spontaneous parametric down-conversion
Rakesh Pradhan, Girish Kulkarni·Feb 8, 2026
The full Schmidt decomposition of spatiotemporally entangled states generated from spontaneous parametric down-conversion (SPDC) has not been carried out until now due to the immense computational complexity arising from the large dimensionalities of...

Renáta Rusnáková, Martin Chovanec, Juraj Gazda·Feb 8, 2026
Multi-Agent Route Planning considers selecting vehicles, each associated with a single predefined route, such that the spatial coverage of a road network is increased while redundant overlaps are limited. This paper gives a formal problem definition,...
