Structured-light-mediated hybrid entanglement between photon polarization and electronic orbital angular momentum
Hiroaki Saito, Nobuhiko Yokoshi·Jul 22, 2026
We propose a minimal quantum-optical scheme for generating hybrid entanglement between photon polarization and electronic orbital angular momentum in a semiconductor quantum disk. A spin--orbit structured two-photon state excites two channels in the ...
Exact Closed-Form Quantum Correlations of Maximally Entangled Qudit States under Arbitrary Non-Markovian Pure Dephasing
Ahmad Akhound·Jul 22, 2026
We study the time evolution of entanglement and quantum discord for a pair of maximally entangled qudits of arbitrary dimension $d$ under non-Markovian pure dephasing, using the exact solution of the independent boson model. Because this solution req...
Analytical Retrieval of Material Parameters in Monolayer Transition-Metal Dichalcogenides Based on a Solvable Exciton Model
Duy-Nhat Ly, Thanh-Son Nguyen, Ngoc-Tram D. Hoang +1 more·Jul 22, 2026
We develop an analytical procedure to retrieve fundamental material parameters of monolayer transition-metal dichalcogenides from optical and magneto-optical exciton spectra, based on the solvable modified Kratzer model. The proposed retrieval proced...
Nuclear Quantum Effects as a Denoising Problem
Weizhou Wang, Jonathan Weare, Aaron R. Dinner·Jul 22, 2026
Nuclear quantum effects are rigorously captured by imaginary-time path integrals, which map the quantum Boltzmann distribution onto a ring polymer of classical replicas. Yet the nuclear masses, the coupling to the environment, and the boundary condit...
Leveraging ECRAM for Edge Continual Learning
Nabila Tasnim, Haoran Liu, Qing Cao +1 more·Jul 22, 2026
Several edge computing platforms, such as autonomous vehicles and smart sensing devices, need to adapt to dynamic environments in real time by learning from new data in the field. Continual learning has emerged as a promising solution for edge traini...
On the global well-posedness for the nonlocal Fokas-Lenells equation with the weighted Sobolev initial data on the line
Zhenya Yan, Guoqiang Zhang, Guancheng Zhu·Jul 22, 2026
We establish the global well-posedness of the Cauchy problem for the reverse space-time nonlocal Fokas-Lenells equation with the weighted Sobolev initial data $q_0(x)\in H^{3}(\mathbb{R}) \cap H^{2,1}(\mathbb{R})$ on the line. We develop the inverse ...
On Solutions of the Killingbeck Potential and Clarifying Comments on a Related Analytical Approach
Fatma Zohra Khaled, Mustafa Moumni, Mokhtar Falek·Jul 21, 2026
The work presents analytical solutions to the Schrodinger equation for the Killingbeck potential, a Hybrid model combining harmonic, linear and Coulomb terms, and which is also an approximate model of Yukawa-type potentials. The radial Schrodinger eq...
Quantum Gravity Simulation: Quantum simulation with a minimum length based on the generalised uncertainty principle
Jack Keable-Elliott, David J. Bacon, Andrew Burbanks +1 more·Jul 21, 2026
We present a recipe for simulating one-dimensional quantum systems for low and high energies with $L$ qubits within the framework of first quantisation. Assuming a minimum grid spacing $ΔL$ in the finite-difference method, the generalised uncertainty...
Bound states of the hydrogen-like atomic systems in plasma environments
Fatma Zohra Khaled, Mustafa Moumni, Mokhtar Falek·Jul 21, 2026
We conduct a non-relativistic study of plasma screening effects on hydrogen-like atomic systems using the Screened Coulomb Potential (SCP i.e. Yukawa potential). The radial Schrödinger equation is first reduced to a bi-confluent Heun (BCH) equation f...
Intelligent qubits
Alexander Givental·Jul 21, 2026
We introduce the method of ``intelligent qubits,'' which replace live observers in Wigner's friend and Frauchiger--Renner thought experiments, in order to expose the source of the paradoxes: tacit substitution of Boolean hidden variables for non-comm...
Examining QRMI as a Unified Interface for Quantum-HPC Integration
Thomas Badts, Tim Boyle, Claudio Carvalho +25 more·Jul 21, 2026
The efficient and scalable integration of quantum resources into high-performance computing (HPC) environments requires standardized mechanisms for resource management, scheduling, and workflow orchestration across diverse and heterogeneous infrastru...
Measurement-Selective Dynamical Symmetry Breaking
Polina Kofman, Elvira Bilokon, Valeriia Bilokon +1 more·Jul 21, 2026
Continuous measurement is commonly associated with decoherence and the loss of symmetry. Here, we show that weak continuous measurements can instead act selectively: depending on the measured observable, they may either preserve or remove a dynamical...
Rank-Adaptive Matrix-Free Atomic Quantum State Tomography
Amirhossein Taherpour, Alireza Sadeghi, Georgios B. Giannakis·Jul 21, 2026
Quantum state tomography estimates an unknown density operator from measurement data. Dense reconstruction however, can be impractical for many-qubit systems because the Hilbert-space dimension grows exponentially. This contribution develops a rank-a...
Quantum codes from classical annealing
Michael A. Perlin, Matthew Steinberg, Ben Criger·Jul 21, 2026
We introduce an adaptive simulated annealing algorithm to search for moderately-sized quantum error-correcting codes with high encoding rates and large distances. Our search targets two classes of stabilizer codes: (1) CSS codes, and (2) a subclass o...
Machine-learned syndrome post-selection for reliable quantum error correction
Tobias Haug, Askery Canabarro, Leandro Aolita·Jul 21, 2026
Quantum error correction can be enhanced by post-selecting out runs that are likely to produce a logical failure, but the most accurate measures for that require costly decoder-level information. We introduce a practical, decoder-agnostic post-select...
Simple, accurate lumped-element models of distributed resonators for superconducting quantum circuits
Elizabeth H. Kunz, Eli M. Levenson-Falk·Jul 21, 2026
Superconducting quantum circuit design is reliant on accurately mapping design parameters to a quantum Hamiltonian. Designers typically rely on computationally intensive finite-element electromagnetic simulations. However, effective circuit-level mod...
Synthesizing superoscillations with just two frequencies
Denys I. Bondar, Diyar Talbayev·Jul 21, 2026
Superoscillations, band-limited signals that locally oscillate faster than their highest Fourier component, have recently enabled superspectroscopy and super-sensing. Previous experiments [Phys. Rev. Lett. 131, 153803 (2023), https://doi.org/10.1103/...
High-purity entanglement mediated by magnons despite weak coupling
Sanchar Sharma·Jul 21, 2026
Entangling distant spins via a shared magnonic bus typically faces a tradeoff: stronger spin-magnon coupling increases the entanglement fidelity, but also the spin decay rate. We propose a protocol that breaks this tradeoff. The magnons couple only t...
Hybrid LLM-Guided Search for Quantum Reservoir Architecture Design
Krishna Bhatia, Gautami Sanjay Naik·Jul 21, 2026
Quantum reservoir computing (QRC) uses fixed quantum dynamics as a high-dimensional temporal feature map and trains only a lightweight classical readout. QRC is attractive for near-term quantum machine learning, but its performance depends strongly o...

Hongbin Ni, Ozgur B. Akan·Jul 21, 2026
Organic electrochemical transistor (OECT)-based molecular communication (MC) receivers connect transport and binding to device current, noise, calibration, and detection. We present MC-BRIDGE (Molecular Communication Bioelectronic Receiver-chain Inte...
