Quantum Materials and Devices

Quantum Materials have a strong impact on quantum science and are the key enabling technologies in different fields.

CNR Nano has a leading role in both experimental and theoretical activities on Quantum Materials. State of the art growth and fabrication facilities and large simulation codes are present in the institute, allowing to study and develop materials for the realization of innovative quantum devices employed on two major platforms: photonics and solid state. Advanced nanostructured materials with reduced dimensionality (zero, one, and bidimensional) based on semiconductor heterostructures, hybrids (semi/super), superconductors, and van der Waals layered materials are employed to fabricate quantum devices with large potential impact in different and technologically relevant application fields such as quantum sensing, quantum computing, quantum metrology (quantum Hall resistance standards), and quantum thermodynamics. In particular, a new CNR infrastructure (PASQUA) has been granted in order to realize quantum cascade lasers for the development of quantum coprocessors.

A part of the research activity is focused on the development of quantum thermal machines, i.e. devices that, exploiting the intrinsic quantum coherence of nanostructures as well as a certain degree of external control, allow for an efficient management of energetic resources in terms of production, storage, and transmission. Theoretical analysis of these devices aims at identifying the conditions of best performance, useful for the optimization of experimental implementations, with the perspective for concrete applications and patents. Investments have been made in order to widen the choice of ultra-low refrigerators to study quantum materials and nanodevices at the lowest possible temperatures, where quantum coherence typically emerges.
