Engineering interactions shape in resonantly driven bosonic gas
Damian Włodzyński, Krzysztof Sacha·Feb 17, 2026
In systems with fast periodic driving, there are special subsets of (resonant) states, which behavior can be described with effective, time-independent Hamiltonian in a rotating reference frame. Here, we show that experimentally feasible system of ul...
Theory of temporal three-photon interference
Nilakshi Senapati, Girish Kulkarni, Anand K. Jha·Feb 17, 2026
The recent demonstrations of cascaded PDC (CPDC) and the hopeful prospects of realizing third-order PDC (TOPDC) for the generation of three-photon entangled states are paving the way for experimental studies on genuine three-photon interference. In t...
Optimal Classification of Three-Qubit Entanglement with Cascaded Support Vector Machine
Fatemeh Sadat Lajevardi, Azam Mani, Ali Fahim·Feb 17, 2026
We introduce a systematic framework for three-qubit entanglement classification using a cascaded architecture of Support Vector Machine (SVM) classifiers. Leveraging the well defined three-qubit structure with the four nested entanglement classes (S,...
Tight Communication Bounds for Distributed Algorithms in the Quantum Routing Model
Fabien Dufoulon, Frédéric Magniez, Gopal Pandurangan·Feb 17, 2026
We present new distributed quantum algorithms for fundamental distributed computing problems, namely, leader election, broadcast, Minimum Spanning Tree (MST), and Breadth-First Search (BFS) tree, in arbitrary networks. These algorithms are (essential...
Observing quantum many-body dynamics in emergent curved spacetime using programmable quantum processors
Brendan Rhyno, Bastien Lapierre, Smitha Vishveshwara +2 more·Feb 17, 2026
We digitally simulate quantum many-body dynamics in emergent curved backgrounds using 80 superconducting qubits on IBM Heron processors. By engineering spatially varying couplings in the spin-$\frac12$ XXZ chain, consistent with the low-energy descri...
Universal entanglement-inspired correlations
Elizabeth Agudelo, Laura Ares, Jan Sperling·Feb 17, 2026
Quantum correlations, crucial for the advantage and advancement of quantum science and technology, arise from the impossibility of expressing a quantum state as a tensor product over a given set of parties. In this work, a generalized notion of corre...
Drone delivery packing problem on a neutral-atom quantum computer
Sara Tarquini, Matteo Vandelli, Francesco Ferrari +2 more·Feb 17, 2026
Quantum architectures based on neutral atoms have gained significant attention in recent years as specialized computational machines due to their ability to directly encode the independent set constraint on graphs, exploiting the Rydberg blockade mec...

Asma Taheri Monfared, Andrea Bombarda, Angelo Gargantini +1 more·Feb 17, 2026
The growing complexity of healthcare systems requires advanced computational models for real-time monitoring, secure data exchange, and intelligent decision-making. Digital Twins (DTs) provide virtual representations of physical healthcare entities, ...
Quantum Reservoir Computing for Statistical Classification in a Superconducting Quantum Circuit
J. J. Prieto-Garcia, A. G. del Pozo-Martín, M. Pino·Feb 17, 2026
We analyze numerically the performance of Quantum Reservoir Computing (QRC) for statistical and financial problems. We use a reservoir composed of two superconducting islands coupled via their charge degrees of freedom. The key non-linear elements th...
Cluster Ising quantum batteries can mimic super-extensive charging power
Anna Pavone, Federico Luigi Cavagnaro, Matteo Carrega +3 more·Feb 17, 2026
Quantum batteries, miniaturized devices able to store and release energy on demand, are promising both because their intrinsic energy and time scales can match those of other quantum technologies and due to the intriguing possibility of achieving sup...
Nonlocality without entanglement in exclusion of quantum states
Satyaki Manna, Anandamay Das Bhowmik·Feb 17, 2026
We study the task of quantum state exclusion, focusing on antidistinguishability and its generalization to $x$-antidistinguishability, under global measurements and local operations with classical communication (LOCC). We also introduce weak and stro...

Hayato Kunugi, Mohsen Rahmani, Yosuke Iyama +8 more·Feb 17, 2026
Deep generative modeling to stochastically design small molecules is an emerging technology for accelerating drug discovery and development. However, one major issue in molecular generative models is their lower frequency of drug-like compounds. To r...
Non-Markovian environment induced Schrödinger cat state transfer in an optical Newton's cradle
Xinyu Zhao, Yan Xia·Feb 17, 2026
In this manuscript, we study the Schrödinger cat state transfer in a quantum optical version of Newton's cradle in non-Markovian environment. Based on a non-Markovian master equation, we show that the cat state can be transferred purely through the m...

Yefeng Song, Junxiao Chen, Xiangyu Yang +3 more·Feb 17, 2026
We investigate how quasiperiodic spatial structure enables protocol-induced acceleration in open quantum systems by analyzing the Pontus-Mpemba effect in one-dimensional chains subject to Markovian dephasing. The dynamics are governed by a Lindblad s...
Non-Markovian environment induced chaos in optomechanical system
You-Lin Xiang, Xinyu Zhao, Yan Xia·Feb 17, 2026
In traditional research, chaos is frequently accompanied by non-linearity, which typically stems from non-linear interactions or external driving forces. However, in this paper, we present the chaotic behavior that is completely attributed to the non...
