Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Ulderico Filippozzi, Graham Kimbell, Davide Pizzirani, Siobhan McKeown Walker, Chiara Cocchi | Summary: We study the superconducting critical fields of two-dimensional electron systems at (111)$mathrm{LaAlO_3/KTaO_3}$ interfaces as a function of electrostatic back-gating. Our work reveals inplane critical fields of unprecedented magnitudes at oxide interfaces. By comparing […]

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Jose Soto Garcia, Natalia Chepiga, , , | Summary: Experiments on chains of Rydberg atoms appear as a new playground to study quantum phase transitions in 1D. As a natural extension, we report a quantitative ground-state phase diagram of Rydberg atoms arranged in a two-leg ladder that […]

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Marc Botifoll, Ivan Pinto-Huguet, Enzo Rotunno, Thomas Galvani, Catalina Coll | Summary: This article introduces a groundbreaking analytical workflow designed for the holistic characterisation, modelling and physical simulation of device heterostructures. Our innovative workflow autonomously, comprehensively and locally characterises the crystallographic information and 3D orientation of the […]

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Marc Botifoll, Ivan Pinto-Huguet, Enzo Rotunno, Thomas Galvani, Catalina Coll | Summary: (Scanning) transmission electron microscopy ((S)TEM) has significantly advanced materials science but faces challenges in correlating precise atomic structure information with the functional properties of devices due to its time-intensive nature. To address this, we introduce […]

Kavli Affiliate: Simon Groblacher | First 5 Authors: Liu Chen, Alexander Rolf Korsch, Cauê Moreno Kersul, Rodrigo Benevides, Yong Yu | Summary: Single-photon sources are of fundamental importance to emergent quantum technologies. Nano-structured optomechanical crystals provide an attractive platform for single photon generation due to their unique engineering freedom and compatibility with on-chip silicon fabrication. […]

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Hanseo Sohn, Jaewon Jung, Jaemin Park, Hyeongyu Jang, Lucas E. A. Stehouwer | Summary: As quantum computing advances towards practical applications, reducing errors remains a crucial frontier for developing near-term devices. Errors in the quantum gates and quantum state readout could result in noisy circuits, which would […]
