Device for MHz-rate rastering of arbitrary 2D optical potentials
Edita Bytyqi, Josiah Sinclair, Joshua Ramette +1 more·Feb 17, 2026
Current architectures for neutral-atom arrays utilize devices such as acousto-optic deflectors (AODs) and spatial light modulators (SLMs) to multiplex a single classical control line into N qubit control lines. Dynamic control is speed-limited by the...
Edge-Local and Qubit-Efficient Quantum Graph Learning for the NISQ Era
Armin Ahmadkhaniha, Jake Doliskani·Feb 17, 2026
Graph neural networks (GNNs) are a powerful framework for learning representations from graph-structured data, but their direct implementation on near-term quantum hardware remains challenging due to circuit depth, multi-qubit interactions, and qubit...
Benchmarking the Lights Out Problem on Real Quantum Hardware
Maksims Dimitrijevs, Maria Palchiha, Abuzer Yakaryilmaz·Feb 17, 2026
We implement the Lights Out problem on a 2D grid and on Mobius ladder graphs and evaluate the performance of Grover's search on real quantum hardware. We use two instances using 9 and 16 qubits, and implement them on publicly available quantum hardwa...
Dynamic Synaptic Modulation of LMG Qubits populations in a Bio-Inspired Quantum Brain
J. J. Torres, E. Romera·Feb 17, 2026
We present a biologically inspired quantum neural network that encodes neuronal populations as fully connected qubits governed by the Lipkin-Meshkov-Glick (LMG) quantum Hamiltonian and stabilized by a synaptic-efficacy feedback implementing activity-...
Gaussian continuous tensor network states: short-distance properties and imaginary-time evolution
Marco Rigobello, Erez Zohar·Feb 17, 2026
We study Gaussian continuous tensor network states (GCTNS) - a finitely-parameterized subclass of Gaussian states admitting an interpretation as continuum limits of discrete tensor network states. We show that, at short distance, GCTNS correspond to ...
Hardware-Agnostic Modeling of Quantum Side-Channel Leakage via Conditional Dynamics and Learning from Full Correlation Data
Brennan Bell, Andreas Trügler, Konstantin Beyer +1 more·Feb 17, 2026
We study a sequential coherent side-channel model in which an adversarial probe qubit interacts with a target qubit during a hidden gate sequence. Repeating the same hidden sequence for $N$ shots yields an empirical full-correlation record: the joint...
Enhanced Superconducting Nanowire Single Photon Detector Performances using Silicon Capping
C. Klein, S. Cohen, T. Descamps +6 more·Feb 17, 2026
Niobium Titanium nitride (NbTiN) based superconducting nanowire single photon detectors (SNSPDs) are known for their high performance across a wide spectral range, from the X-ray to the mid-infrared. Nonetheless, fabrication challenges and performanc...
Limits of Clifford Disentangling in Tensor Network States
Sergi Masot-Llima, Piotr Sierant, Paolo Stornati +1 more·Feb 17, 2026
Tensor network methods leverage the limited entanglement of quantum states to efficiently simulate many-body systems. Alternatively, Clifford circuits provide a framework for handling highly entangled stabilizer states, which have low magic and are t...
Entanglement-assisted Hamiltonian dynamics learning
Ayaka Usui, Guillermo Abad-López, Hari krishnan SV +2 more·Feb 17, 2026
Approximating the dynamics given by a complex many-body Hamiltonian with a simpler effective model lies at the interface of quantum Hamiltonian learning and quantum simulation. In this context, quantum generative adversarial networks (QGANs) have bee...
Robustness of Kardar-Parisi-Zhang-like transport in long-range interacting quantum spin chains
Sajant Anand, Jack Kemp, Julia Wei +3 more·Feb 17, 2026
Isotropic integrable spin chains such as the Heisenberg model feature superdiffusive spin transport belonging to an as-yet-unidentified dynamical universality class closely related to that of Kardar, Parisi, and Zhang (KPZ). To determine whether thes...
QwaveMPS: An efficient open-source Python package for simulating non-Markovian waveguide-QED using matrix product states
Sofia Arranz Regidor, Matthew Kozma, Stephen Hughes·Feb 17, 2026
QwaveMPS is an open-source Python library for simulating one-dimensional quantum many-body waveguide systems using matrix product states (MPS). It provides a user-friendly interface for constructing, evolving, and analyzing quantum states and operato...
Deformed Heisenberg algebra and its Hilbert space representations
Latévi M. Lawson, Ibrahim Nonkané, Kinvi Kangni·Feb 17, 2026
A deformation of Heisenberg algebra induces among other consequences a loss of Hermiticity of some operators that generate this algebra. Therefore, these operators are not Hermitian, nor is the Hamiltonian operator built from them. In the present pap...
Entanglement in the Dicke subspace
Aabhas Gulati, Ion Nechita, Clément Pellegrini·Feb 17, 2026
In this paper, we provide a complete mathematical theory for the entanglement of mixtures of Dicke states. These quantum states form an important subclass of bosonic states arising in the study of indistinguishable particles. We introduce a tensor-ba...
Steady state coherence in a qubit is incompatible with a quantum map
Hans C. Fogedby·Feb 17, 2026
We consider the recent proposal of steady state coherences in a single qubit in the case of a composite system-bath interaction. Based on a field theoretical approach we reanalyse the issue within a Redfield description. We find that the Redfield app...
