A multi-ansatz variational quantum solver for compressible flows
Shaobo Yao, Zhiyu Duan, Ziteng Wang +2 more·Aug 28, 2025
Simulating nonlinear partial differential equations (PDEs) such as the Navier--Stokes (NS) equations remains computationally intensive, especially when implicit time integration is used to capture multiscale flow dynamics. This work introduces a hybr...
Fourier Fingerprints of Ansatzes in Quantum Machine Learning
Melvin Strobl, M. E. Sahin, Lucas van der Horst +4 more·Aug 28, 2025
Typical schemes to encode classical data in variational quantum machine learning (QML) lead to quantum Fourier models with $\mathcal{O}(\exp(n))$ Fourier basis functions in the number of qubits. Despite this, in order for the model to be efficiently ...

Rojan Abolhassani, Lukas Scarfe, Francesco Di Colandrea +3 more·Aug 28, 2025
Quantum key distribution (QKD) allows secure key exchange based on the principles of quantum mechanics, with higher-dimensional photonic states offering enhanced channel capacity and resilience to noise. Free-space QKD is crucial for global networks ...
Introducing the Quantum Economic Advantage Online Calculator
Frederick Mejia, Hans Gundlach, Jayson Lynch +5 more·Aug 28, 2025
Developing a systematic view of where quantum computers will outperform classical ones is important for researchers, policy makers and business leaders. But developing such a view is challenging because quantum advantage analyses depend not only on a...
Quantum Advantage in Computational Chemistry?
Hans Gundlach, K. Sharkey, Jayson Lynch +8 more·Aug 28, 2025
For decades, computational chemistry has been posited as one of the areas in which quantum computing would revolutionize. However, the algorithmic advantages that fault-tolerant quantum computers have for chemistry can be overwhelmed by other disadva...
Quantum algorithms for equational reasoning
Davide Rattacaso, Daniel Jaschke, Marco Ballarin +2 more·Aug 28, 2025
We introduce quantum normal form reduction, a quantum computational framework for analyzing abstract symbolic expressions - such as strings, algebraic formulas, or quantum circuits - that are equivalent under a given set of transformation rules. Thes...
Unitary Synthesis with AlphaZero via Dynamic Circuits
Xavier Valcarce, Bastien Grivet, Nicolas Sangouard·Aug 28, 2025
Unitary synthesis is the process of decomposing a target unitary transformation into a sequence of quantum gates. This is a challenging task, as the number of possible gate combinations grows exponentially with the circuit depth. In this manuscript, ...
Application of Quantum Convolutional Neural Networks for MRI-Based Brain Tumor Detection and Classification
Sugih Pratama Nugraha, Ariiq Islam Alfajri, T. Sumaryada +4 more·Aug 28, 2025
This study explores the application of Quantum Convolutional Neural Networks (QCNNs) for brain tumor classification using MRI images, leveraging quantum computing for enhanced computational efficiency. A dataset of 3,264 MRI images, including glioma,...
Qubit Health Analytics and Clustering for HPC-Integrated Quantum Processors
Xiaolong Deng, L. Schulz, Martin Schulz·Aug 28, 2025
Quantum computing in supercomputing centers requires robust tools to analyze calibration datasets, predict hardware performance, and optimize operational workflows. This paper presents a data-driven framework for processing calibration metrics. Our m...
Louvre: Relaxing Hardware Requirements of Quantum LDPC Codes by Routing with Expanded Quantum Instruction Set
Runshi Zhou, Fang Zhang, Hui-Hai Zhao +3 more·Aug 28, 2025
Generalized bicycle codes (GB codes) represent a promising family of quantum low-density parity-check codes, characterized by high code rates and relatively local qubit connectivity. A subclass of the GB code called bivariate bicycle codes (BB codes)...

Almudena Carrera Vazquez, Aleksandros Sobczyk·Aug 28, 2025
Approximating the $k$-th spectral gap $\Delta_k=|\lambda_k-\lambda_{k+1}|$ and the corresponding midpoint $\mu_k=\frac{\lambda_k+\lambda_{k+1}}{2}$ of an $N\times N$ Hermitian matrix with eigenvalues $\lambda_1\geq\lambda_2\geq\ldots\geq\lambda_N$, i...
Overhead in quantum circuits with time-multiplexed qubit control
M. Richter, Ingrid Strandberg, Simone Gasparinetti +1 more·Aug 28, 2025
When scaling up quantum processors in a cryogenic environment, it is desirable to limit the number of qubit drive lines going into the cryostat, since fewer lines makes cooling of the system more manageable and the need for complicated electronics se...
Quantum-Enhanced Analysis and Grading of Vocal Performance
Rohan Agarwal·Aug 28, 2025
We present QuantumMelody, a hybrid quantum-classical method for objective singing assessment. Grouped vocal features (pitch stability, dynamics, timbre) are encoded into a small simulated quantum circuit; all nine qubits are initialized with a Hadama...
