Trond Hjerpekjøn Haug
Trond received his MSc in Nanotechnology from the Norwegian University of Science and Technology in 2020, where he studied spin waves in 2D antiferromagnetic insulators. Before starting his PhD, Trond worked as an engineer at Sensonor AS developing dry etch processes for MEMS sensors. He joined QPL as a PhD student in the summer of 2022 and focuses on hybrid microwave-optical architectures for quantum technologies enabled by quantum transducers, as well as solutions to heating in optomechanical transducers. In his free time Trond likes hiking, skiing and reading.
David has recieved his BSc, and expects to receive his MSc, in Physics at Chalmers University of Technology. During his master, he specialized in computational physics and quantum information processing. He joined QPL in the spring of 2023 to write his MSc thesis on inverse design of hybrid electro-optomechanical quantum devices, and now continues in the group for his PhD research. In his free time he enjoys hiking, skiing, swimming and climbing, as well as reading fantasy, playing board games, and singing (though mostly to himself).
Raphaël Van Laer
Raphaël leads an interdisciplinary research team in photonics and quantum technologies at Chalmers University of Technology. He explores the flow of and interactions between light, sound, and microwaves for quantum information processing. See here for his short CV.
He received a PhD in silicon photonics at Ghent University-imec (Photonics Research Group), making contributions to integrated nonlinear optics and optomechanics. The results were recognized with an IEEE Graduate Student Scholarship and a VOCATIO award. Afterwards he worked mainly on thin-film lithium niobate, heterogeneous photonic integration, and quantum microwave-to-optics conversion as a Marie Skłodowska-Curie postdoctoral fellow at Stanford University (LINQS). His team is supported by the Wallenberg Centre for Quantum Technology, the Swedish Foundation for Strategic Research with a Future Research Leader Grant, and by the European Research Council with a Starting Grant.
His research revolves around two overarching questions. First, what are the physical limits to information processing in a constrained space? Second, can we realize large-scale coherent communication, sensing, and computation?
