Welcome to the Artificial Quantum Systems (ArQuS) laboratory!

We are an experimental research group at the University of Trieste. Our work centers on the cooling, trapping, and coherent control of two-electron atoms using high-precision optical manipulation and spectroscopic techniques, achieving resolution down to the single atom to engineer scalable quantum platforms. Our research spans a broad range of topics in quantum science and technology, from fundamental studies of many-body physics to quantum optics and metrology and the development of quantum networks and modular quantum computing architectures.

The laboratories are led by Prof. Francesco Scazza and Dr. Matteo Marinelli as a joint effort between University of Trieste, Institute of Optics of the Italian National Research Council (CNR-INO), and Institute Officina dei Materiali of the Italian National Research Council (CNR-IOM). We are financially supported by ERC Starting Grant OrbiDynaMIQs under the European Union’s Horizon 2020 research and innovation programme (Grant Agreement no. 949438), by the Italian Ministry of University and Research (MUR) under the FARE initiative and the PNRR Next-Generation EU National Quantum Science and Technology Institute (NQSTI), and by the autonomous region of Friuli Venezia Giulia (EQUIP-FVG).
