Quantum engineering is a vital breeding ground for future key technologies, from quantum computing and energy-efficient optoelectronics to medical applications. However, the search for suitable material platforms is lagging. Guidelines may be performance-based, e.g., related to the efficiency and reliability of quantum-state preparation, transfer, and read-out. On the other hand, a more widespread deployment of quantum technology may also need to consider aspects such as scalability, tunability, integrability, versatility, or cost-efficiency. In this respect, halide perovskites and other metal halides of various dimensionalities invite the question whether their solution-processability, spectral tunability, strong light-matter interaction, and generally intriguing set of optical and structural properties could indeed represent a suitable material platform for quantum-engineered devices.
PeroQuant25 will provide a forum for discussing the latest scientific discoveries in the field of halide perovskites and perovskitoids with the aim of jointly exploring emerging opportunities in the realm of quantum information science and quantum technology. We invite both experimental and theoretical advances to better create, understand, and utilize metal halides as tunable and scalable materials for quantum-engineered devices.

Grigorios Itskos obtained a B.Sc. in Physics in 1997 from University of Thessaloniki, Greece and carried out his PhD studies at SUNY at Buffalo, USA (Ph.D. in Physics 2003), under the supervision of Prof. Athos Petrou within the newly-born field of semiconductor spintronics. He worked as postdoctoral researcher (Imperial College London, 2003-2007) under the supervision of Profs. Donal Bradely and Ray Murray, focusing on photophysical studies of hybrid organic-inorganic semiconductors. In September 2007 he was hired as a faculty member at the Department of Physics, University of Cyprus (Lecturer 2007-2011, Assistant Professor 2011- 2017, Associate Professor 2017- now). His group research activities focus on optical studies of inorganic, organic and hybrid solution-processed semiconductors, with recent emphasis on the characterization and optoelectronic applications of semiconductor nanocrystals.
Claudine Katan (born Hoerner) received her Ph.D. in physics (nonlinear optics) from the University of Strasbourg (ULP), France in 1992. She subsequently served as a lecturer in physics at the University of Rennes (UR1), France, before being appointed as a CNRS Research Investigator in the Physics Department at Rennes in 1993. Until 2003, her research interests concerned the properties of molecular charge-transfer crystals and the topology of electron densities mainly through approaches based on density functional theory (e.g. the CP-PAW code by P. E. Blöchl, IBM-Zurich). She then joined the Chemistry Department at Rennes and turned her research interests toward the structural, electronic and linear/nonlinear optical properties of molecular and supramolecular chromophores using various theoretical approaches—from modeling to state-of-the-art electronic structure calculations (e.g. CEO methodology by S. Tretiak, LANL) . Since the end of 2010, her research has also been devoted to 3D and 2D crystalline materials of the family of halide perovskites based on solid-state physics concepts. Overall, her theoretical work is closely related to the experimental research developed in-house and through international collaboratorations.
