Quantum Reservoir Computing for Credit Card Default Prediction on a Neutral Atom Platform
In this paper, we define and benchmark a hybrid quantum-classical machine learning pipeline by performing a binary classification task applied to a real-world financial use case. Specifically, we implement a Quantum Reservoir Computing (QRC) layer within a classical routine that includes data preprocessing and binary classification. The reservoir layer has been executed on QuEra's Aquila, a 256-qubit neutral atom simulator, using two different types of encoding: position and local detuning. In …

ATOM: A Pretrained Neural Operator for Multitask Molecular Dynamics
Molecular dynamics (MD) simulations underpin modern computational drug dis- covery, materials science, and biochemistry. Recent machine learning models provide high-fidelity MD predictions without the need to repeatedly solve quantum mechanical forces, enabling significant speedups over conventional pipelines. Yet many such methods typically enforce strict equivariance and rely on sequential rollouts, thus limiting their flexibility and simulation efficiency. They are also com- monly single-tas…

Thermality and athermality in the Unruh effect
In idealized treatments of the Unruh effect, a two-level atom is accelerated in a prescribed classical trajectory through the vacuum of a quantum field -- the Unruh bath -- which causes the atom's internal state to thermalize to a temperature proportional to the acceleration. This happens via emission and absorption of quanta by the atom, leading to a detailed balance between fluctuations in the Unruh bath and associated dissipation of the atom's internal energy. In any physical manifestation o…

Beyond Ensembles: Simulating All-Atom Protein Dynamics in a Learned Latent Space
Simulating the long-timescale dynamics of biomolecules is a central challenge in computational science. While enhanced sampling methods can accelerate these simulations, they rely on pre-defined collective variables that are often difficult to identify. A recent generative model, LD-FPG, demonstrated that this problem could be bypassed by learning to sample the static equilibrium ensemble as all-atom deformations from a reference structure, establishing a powerful method for all-atom ensemble g…

A computationally efficient subspace harmonic relaxation algorithm for coarse-graining of molecular systems with nearly exact thermodynamic consistency
In a recent paper, J. Chem. Phys. 162, 214101 (2025), a novel approach for the rigidification of a molecular cluster was proposed, in which starting with an all-atom (AA) potential, a coarse-grained (CG) potential for the associated cluster of rigid monomers was constructed directly. The method is based on using the harmonic approximation for the fast intramolecular degrees of freedom. While conceptually primitive, the resulting CG model turned out to be surprisingly accurate for selected water…

Using all-atom molecular dynamics simulations, we studied premelting layers at the basal face of ice in contact with styrene-butadiene rubber from 254 to 269 K. Despite its hydrophobicity, rubber enhances structural disorder of interfacial water, promoting premelting. In contrast, water mobility is suppressed by confinement from polymer chains, leading to glassy dyn…

On the Characteristic polynomial of ABS Matrix and ABS-Energy of Some Graphs

In this article, we determine the characteristic polynomial of the $ABS$ matrix for certain specific classes of graphs. Furthermore, we compute the $ABS$ eigenvalues and the $ABS$ energy for these clas…

These issues highlight the necessity of accurate atom-to-atom correspondence as a prerequisite for meaningful alignment.…

The inclusion of these effects, extending beyond the previously considered point-like cloud approximation, naturally allow us to study the smooth transition between the coherent and i…

However, in practice the finite pulse duration makes the sensor scale factor dependent upon the pulse shape and sensitive to variation…

Although both rely on interference, the interfering components of clocks are spatially colocated, whereas atom interferometers are based on spatial superpositions. Both the electromagnetic fields that drive the transitions and generate superpositions, while propagating through spacetime, as well a…

A Scalable Heuristic for Molecular Docking on Neutral-Atom Quantum Processors
Molecular docking is a critical computational method in drug discovery used to predict the binding conformation and orientation of a ligand within a protein's binding site. Mapping this challenge onto a graph-based problem, specifically the Maximum Weighted Independent Set (MWIS) problem, allows it to be addressed by specialized hardware such as neutral-atom quantum processors. However, a significant bottleneck has been the size mismatch between biologically relevant molecular systems and the l…

Non-local mass superpositions and optical clock interferometry in atomic ensemble quantum networks
Quantum networks are emerging as powerful platforms for sensing, communication, and fundamental tests of physics. We propose a programmable quantum sensing network based on entangled atomic ensembles, where optical clock qubits emulate mass superpositions in atom and atom-clock interferometry. Our approach uniquely combines scalability to large atom numbers with minimal control requirements, relying only on collective addressing of internal atomic states. This enables the creation of both non-l…

Gradient-Based Inverse Optimization of Atom-Chip Wire Currents for BEC Transport
Modulating wire currents to shift a magnetic trap along an atom chip enables smooth contact-free delivery of Bose-Einstein condensates but can deform the confinement profile causing parametric heating and atom loss. We introduce a fast simulation framework based on inverse optimization that, given an initial trap and a predefined trajectory over time, computes a wire current schedule that transports the atoms and restores the trap geometry upon arrival. We assess trap's minimum energy, lateral …

Impact of Force Noise on the Visibility of STA-Based Atom Interferometers
In a previous work, we designed a compact atom interferometer to measure homogeneous constant forces guiding the arms via shortcuts to adiabatic paths. Within this scheme we drive the atom by moving spin-dependent traps, and design a force $f(t)$ to compensate inertial terms in the moving frame. In this paper we analyze how robust our interferometer is against some realistic noisy deviation from the unperturbed value of the force $f(t)$. The complex overlap of the atom wave functions for each a…

From quantum feature maps to quantum reservoir computing: perspectives and applications
We explore the interplay between two emerging paradigms: reservoir computing and quantum computing. We observe how quantum systems featuring beyond-classical correlations and vast computational spaces can serve as non-trivial, experimentally viable reservoirs for typical tasks in machine learning. With a focus on neutral atom quantum processing units, we describe and exemplify a novel quantum reservoir computing (QRC) workflow. We conclude exploratively discussing the main challenges ahead, whi…

Decoherence-free interaction and maximally entangled state generation in double-giant-atom semi-infinite waveguide systems
Giant atoms are artificial atoms that can couple to a waveguide non-locally. Previous work has shown that two giant atoms in a braided configuration can interact through a one-dimensional infinite waveguide, with both individual and collective atomic relaxation being fully suppressed. In this paper, however, we show that the decoherence-free interaction (DFI) between two giant atoms can be realized in both braided and nested configurations when the waveguide is semi-infinite. This protected int…

Robust Control and Entanglement of Qudits in Neutral Atom Arrays
Quantum devices comprised of elementary components with more than two stable levels - so-called qudits - enrich the accessible Hilbert space, enabling applications ranging from fault-tolerant quantum computing to simulating complex many-body models. While several quantum platforms are built from local elements that are equipped with a rich spectrum of stable energy levels, schemes for the efficient control and entanglement of qudits are scarce. Importantly, no experimental demonstration of mult…
