Interdisciplinary research is a defining feature of modern science, and this trend is especially pronounced in the field of quantum technologies. Physics, chemistry, mathematics, and biology form the core fields of research at the Centre for Quantum Metamaterials of the HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM). Prof. Alexei Vagov, director of the centre, discusses its key activities, which focus on exploring the prospects of creating materials with predefined properties through manipulating their structure at the quantum level.
