A demonstration that classical gravity does not produce entanglement

Mike D. Schneider, Nick Huggett, Niels Linnemann·Nov 24, 2025

Once again, dispute has arisen over the interpretation of proposed quantum information theory experiments to probe the quantum nature of gravity by testing for gravitationally induced entanglement (GIE) between two spatially separated massive particl...

Entropic Dynamics approach to Quantum Electrodynamics

Ariel Caticha·Nov 24, 2025

Entropic dynamics (ED) is a framework that allows one to derive quantum theory as a Hamilton-Killing flow on the cotangent bundle of a statistical manifold. These flows are such that they preserve the symplectic and the (information) metric geometrie...

Synchronized Aharonov-Bohm Motifs via Engineered Dissipation

Christopher W. Wächtler, Gloria Platero·Nov 24, 2025

The interplay between external gauge fields and lattice geometry can induce extreme localization dynamics through complete destructive interference. We show that combining this flux-induced localization with engineered dissipation leads to robust spi...

YBa$_2$Cu$_3$O$_7$ nano-constriction Josephson junctions and SQUIDs fabricated by focused helium-ion-beam irradiation

Christoph Schmid, Christopher Buckreus, David Haas +9 more·Nov 24, 2025

By focused $30\,\mathrm{keV}$ He ion beam irradiation, epitaxially grown YBa$_2$Cu$_3$O$_7$ (YBCO) thin films can be driven from the superconducting to the insulating state with increasing irradiation dose. A properly chosen dose suppresses supercond...

Flexible Genetic Algorithm for Quantum Support Vector Machines

Nguyen Minh Duc, Vu Tuan Hai, Le Bin Ho +1 more·Nov 24, 2025

Quantum Support Vector Machines (QSVM) is one of the most promising frameworks in quantum machine learning, yet their performance depends on the design of the feature map. Conventional approaches rely on fixed quantum circuits, which often fail to ge...

Feature Ranking in Credit-Risk with Qudit-Based Networks

Georgios Maragkopoulos, Lazaros Chavatzoglou, Aikaterini Mandilara +1 more·Nov 24, 2025

In finance, predictive models must balance accuracy and interpretability, particularly in credit risk assessment, where model decisions carry material consequences. We present a quantum neural network (QNN) based on a single qudit, in which both data...

SPARTA: $χ^2$-calibrated, risk-controlled exploration-exploitation for variational quantum algorithms

Mikhail Zubarev·Nov 24, 2025

Variational quantum algorithms face a fundamental trainability crisis: barren plateaus render optimization exponentially difficult as system size grows. While recent Lie algebraic theory precisely characterizes when and why these plateaus occur, no p...

Noisy dynamics of confined quantum walks on a chip

L. Sansoni, E. Stefanutti, C. Benedetti +8 more·Nov 24, 2025

Quantum walks represent an excellent testbed for investigating the interplay between unitary coherent and incoherent dissipative processes. Thanks to photonic quantum interferometers of considerable size, experimental studies could be performed, devo...

Web of Non-invertible Dualities for (2+1) Dimensional Models with Subsystem Symmetries

Avijit Maity, Vikram Tripathi, Andriy H. Nevidomskyy·Nov 24, 2025

We extend non-invertible duality concepts from one-dimensional systems to two spatial dimensions by constructing a web of non-invertible dualities for lattice models with subsystem symmetries. For the $\mathbb{Z}_2 \times \mathbb{Z}_2$ subsystem symm...

HOPPS: Hardware-Aware Optimal Phase Polynomial Synthesis with Blockwise Optimization for Quantum Circuits

Xinpeng Li, Ji Liu, Shuai Xu +2 more·Nov 24, 2025

Blocks composed of {CNOT, Rz} are ubiquitous in modern quantum applications, notably in circuits such as QAOA ansatzes and quantum adders. After compilation, many of them exhibit large CNOT counts or depths, which lowers fidelity. Therefore, we intro...
