Progress in the development of quantum algorithms and software
Anastasiia S. Nikolaeva, D. O. Konina, A. Antipov +10 more·May 7, 2025
A quantum processor, like any computing device, requires the development of both hardware and the necessary set of software solutions, starting with quantum algorithms and ending with means of accessing quantum devices. As part of the roadmap for the...
A review of applications of Quantum Energy Teleportation: from experimental tests to thermodynamics and spacetime engineering
Boris Ragula, Eduardo Mart'in-Mart'inez·May 7, 2025
Quantum energy teleportation (QET) exploits the existence of correlations to enable remote energy transfer without the need for physical energy carriers between emitter and receiver. This paper presents a review of the thermodynamic foundations of QE...
Applied Post Quantum Cryptography: A Practical Approach for Generating Certificates in Industrial Environments
Nino Ricchizzi, Christian Schwinne, Jan Pelzl·May 7, 2025
The transition to post-quantum cryptography (PQC) presents significant challenges for certificate-based identity management in industrial environments, where secure onboarding of devices relies on long-lived and interoperable credentials. This work a...
Quantum Artificial Intelligence for Software Engineering: the Road Ahead
Xinyi Wang, Shaukat Ali, Paolo Arcaini·May 7, 2025
In order to handle the increasing complexity of software systems, Artificial Intelligence (AI) has been applied to various areas of software engineering, including requirements engineering, coding, testing, and debugging. This has led to the emergenc...
Adaptive folding and noise filtering for robust quantum error mitigation
Kathrin F. Koenig, Finn Reinecke, Thomas Wellens·May 7, 2025
Coping with noise in quantum computation poses significant challenges due to its unpredictable nature and the complexities of accurate modeling. This paper presents noise-adaptive folding, a technique that enhances zero-noise extrapolation (ZNE) thro...
Approximate quadratization of high-order hamiltonians for combinatorial quantum optimization
Sabina Druagoi, Alberto Baiardi, Daniel J. Egger·May 7, 2025
Combinatorial optimization problems have wide-ranging applications in industry and academia. Quantum computers may help solve them by sampling from carefully prepared Ansatz quantum circuits. However, current quantum computers are limited by their qu...
ARDNS-FN-Quantum: A Quantum-Enhanced Reinforcement Learning Framework with Cognitive-Inspired Adaptive Exploration for Dynamic Environments
Umberto Gonccalves de Sousa·May 7, 2025
Reinforcement learning (RL) has transformed sequential decision making, yet traditional algorithms like Deep Q-Networks (DQNs) and Proximal Policy Optimization (PPO) often struggle with efficient exploration, stability, and adaptability in dynamic en...
Privacy-preserving neutral atom-based quantum classifier towards real healthcare applications
Ettore Canonici, Filippo Caruso·May 7, 2025
Technological advances in Artificial Intelligence (AI) and Machine Learning (ML) for the healthcare domain are rapidly arising, with a growing discussion regarding the ethical management of their development. In general, ML healthcare applications cr...
Scalable Asynchronous Single Flux Quantum Up-Down Counter Using Josephson Trapping Lines and $\alpha$-Cells
M. A. Karamuftuoglu, Beyza Zeynep Ucpinar, S. Razmkhah +1 more·May 7, 2025
We present a scalable, asynchronous up-down counter architecture implemented using single-flux quantum logic to enable efficient state management in superconductor digital systems. The proposed design eliminates the reliance on clocked storage elemen...
A Multi-Scale Quantum Framework for Evaluating Metal-Organic Frameworks in Carbon Capture
Tom W. A. Montgomery, Adrián Varela-Álvarez, Sam Genway +2 more·May 7, 2025
Metal Organic Frameworks (MOFs) are promising materials to help mitigate the effects of global warming by selectively absorbing $\text{CO}_{2}$ for direct capture. Accurate quantum chemistry simulations are a useful tool to help select and design opt...
Impact and mitigation of Hamiltonian characterization errors in digital-analog quantum computation
Mikel Garcia-de-Andoin, Alatz Álvarez-Ahedo, Adrián Franco-Rubio +1 more·May 6, 2025
Digital-analog is a universal quantum computing paradigm which employs the natural entangling Hamiltonian of the system and single-qubit gates as resources. Here, we study the stability of these protocols against Hamiltonian characterization errors. ...
Environmental Quantum States Trigger Emission in Nonlinear Photonics
Jia-Qi Li, Xin Wang·May 6, 2025
Light-matter interactions are traditionally governed by two fundamental paradigms: spontaneous and stimulated radiation. However, in nonlinear multi-photon regimes, these classical mechanisms break down, revealing new possibilities for light emission...
On the non-Markovian quantum stochastic network dynamics
Haijin Ding, Guofeng Zhang·May 6, 2025
In this paper, we investigate non-Markovian quantum dynamics from the perspective of quantum noises in a network of atoms mediated by a waveguide. In such networks, quantum coherent feedback control becomes achievable when coherent fields (or quantum...
Experimental Side-Channel-Secure Quantum Key Distribution over 200 km
Yang Zhou, Jing-Yang Liu, Chun-Hui Zhang +4 more·May 6, 2025
Quantum key distribution (QKD) enables two remote parties to share encryption keys with information-theoretic security guaranteed by physical laws. Side-channel-secure QKD (SCS-QKD) has attracted considerable attention because it simultaneously remov...
