Kavli Affiliate: Eliska Greplova | First 5 Authors: Vinicius Hernandes, Thomas Spriggs, Saqar Khaleefah, Eliska Greplova, | Summary: Neural quantum states (NQS) have emerged as a powerful tool for approximating quantum wavefunctions using deep learning. While these models achieve remarkable accuracy, understanding how they encode physical information remains an open challenge. In this work, we […]

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Yuta Matsumoto, Maxim De Smet, Larysa Tryputen, Sander L. de Snoo, Sergey V. Amitonov | Summary: The scalability and power of quantum computing architectures depend critically on high-fidelity operations and robust and flexible qubit connectivity. In this respect, mobile qubits are particularly attractive as they enable dynamic […]

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Thomas R. Beauchamp, Hana Jirovská, Scarlett Gauthier, Stephanie Wehner, | Summary: We propose an architecture for scheduling network operations enabling the end-to-end generation of entanglement according to user demand. The main challenge solved by this architecture is to allow for the integration of a network schedule with […]

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Sam R. Katiraee-Far, Yuta Matsumoto, Brennan Undseth, Maxim De Smet, Valentina Gualtieri | Summary: Developing optimal strategies to calibrate quantum processors for high-fidelity operation is one of the outstanding challenges in quantum computing today. Here, we demonstrate multiple examples of high-fidelity operations achieved using a unified global […]

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Niels T. Pronk, Bowy M. La Rivière, Natalia Chepiga, , | Summary: We report a phase diagram of the antiferromagnetic spin-1 chain with nearest-neighbor Heisenberg and three-site interactions in the presence of single-ion anisotropy. We show that the Gaussian and Ising transitions that separate the topological Haldane […]

Kavli Affiliate: Simon Groblacher | First 5 Authors: Gaia Da Prato, Yong Yu, Ronald Bode, Simon Gröblacher, | Summary: A tunable magnetic field at low temperatures is essential for numerous applications, including spintronics, magnetic resonance imaging, and condensed matter physics. While commercial superconducting vector magnets are available, they are complex, expensive, and often not adaptable […]

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Greta Segantini, Ludovica Tovaglieri, Chang Jae Roh, Chih-Ying Hsu, Seongwoo Cho | Summary: In this study, we explore the ferroelectric domain structure and mechanical properties of PbTiO$_3$-based membranes, which develops a well-ordered and crystallographic-oriented ripple pattern upon release from their growth substrate. The ferrolectric domain structure […]

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Álvaro G. Iñesta, Bethany Davies, Sounak Kar, Stephanie Wehner, | Summary: Entanglement buffers are systems that maintain high-quality entanglement, ensuring it is readily available for consumption when needed. In this work, we study the performance of a two-node buffer, where each node has one long-lived quantum memory […]

Kavli Affiliate: Michael Wimmer | First 5 Authors: Adam Celarek, George Kopanas, George Drettakis, Michael Wimmer, Bernhard Kerbl | Summary: Since its introduction, 3D Gaussian Splatting (3DGS) has become an important reference method for learning 3D representations of a captured scene, allowing real-time novel-view synthesis with high visual quality and fast training times. Neural Radiance […]

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Bart van der Vecht, Atak Talay Yücel, Hana Jirovská, Stephanie Wehner, | Summary: Recently, a first-of-its-kind operating system for programmable quantum network nodes was developed, called QNodeOS. Here, we present an extension of QNodeOS called Qoala, which introduces (1) a unified program format for hybrid interactive classical-quantum […]
